Description

헥사아릴비스이미다졸계 혼합 광개시제 및 응용Hexaarylbisimidazole-based mixed photoinitiator and applications

본 발명은 광경화 기술 분야에 속하는 것으로 상세하게는 헥사아릴비스이미다졸계 혼합 광개시제, 상기 광개시제를 포함하는 감광성 수지 조성물 및 감광성 수지 조성물의 응용에 관한 것이다.The present invention belongs to the field of photocuring technology, and more particularly, to a hexaarylbisimidazole-based mixed photoinitiator, a photosensitive resin composition including the photoinitiator, and applications of the photosensitive resin composition.

인쇄 회로 기판, 집적 회로, 박막 트랜지스터, 반도체 패키징 등의 마이크로 전자 회로의 제조에는 일반적으로 포토 리소그래피 공정(Photolithography)을 이용해 레지스트 패턴을 형성하는 방법이 포함된다. 포토 리소그래피 공정에서는, 기판에 코팅된 감광성 수지 조성물층 또는 적층체에 소정의 패턴을 갖는 마스크를 조합하여 노광을 수행하고, 그 다음 노광부와 비노광부에 대한 용해도가 다른 현상액으로 현상하여 레지스트 패턴을 형성하고, 이어서, 레지스트 패턴을 마스크로 하여 기판에 도금 및/또는 에칭 공정 등을 수행함으로써 원하는 도체 패턴을 기판에 형성한다. Manufacturing of microelectronic circuits such as printed circuit boards, integrated circuits, thin film transistors, and semiconductor packaging generally includes a method of forming a resist pattern using a photolithography process. In the photolithography process, exposure is performed by combining a mask having a predetermined pattern on a photosensitive resin composition layer or laminate coated on a substrate, and then developing with a developing solution having different solubility for the exposed and unexposed areas to form a resist pattern. Then, a desired conductor pattern is formed on the substrate by performing a plating and/or etching process on the substrate using the resist pattern as a mask.

정밀 전자 기기의 인쇄 회로 기판의 미세화와 함께 고감광도, 고분해능 및 해상도를 갖는 감광성 수지 조성물이 연구의 이슈가 되었다. 그중, 감광성 수지 조성물의 핵심 성분 중 하나인 광개시제는 높은 개시 효율, 우수한 시스템 상용성 및 우수한 용해도 등이 요구된다. 헥사아릴비스이미다졸계 화합물 (HABI)은 매우 중요한 자유 라디칼 광개시제로서 자외선의 작용하에서 광분해로 대분자 자유 라디칼을 생성할 수 있으나, HABI 및 그 유도체는 일반적인 상태에서 고체이기에 시스템에서의 용해도가 좋지 않다. 일면 광개시제의 완전한 용해 및 분산은 수지 시스템에서의 개시 효율에 직접 관계된다.Along with miniaturization of printed circuit boards of precision electronic devices, photosensitive resin compositions having high photosensitivity, high resolution and resolution have become issues of research. Among them, the photoinitiator, which is one of the core components of the photosensitive resin composition, requires high initiation efficiency, excellent system compatibility, and excellent solubility. Hexaarylbisimidazole-based compound (HABI) is a very important free radical photoinitiator and can generate large molecular free radicals through photolysis under the action of ultraviolet light. . The complete dissolution and dispersion of the one-sided photoinitiator is directly related to the initiation efficiency in the resin system.

용해도 및 감광도에 대한 필요 외에도, 현재 연구에서는 또한 감광성 조성물이 수상(aqueous phase)에서 현상되거나 처리될 수 있기를 많이 강조한다. 감광성 수지 조성물의 조성성분이 현상액 내 용해도가 낮다면, 현상 공정이 반복될 경우, 현상액에 분산성을 떨어뜨리는 불용성 성분이 크게 증가하여 응집물(슬러지)이 생성되고, 현상 공정이 계속되는 경우, 응집물이 기판에 다시 부착되어 단락이 발생할 수 있고, 현상 탱크의 배관이 막힐 수도 있다. Besides the need for solubility and photosensitivity, current research also places great emphasis on the ability of photosensitive compositions to be developed or processed in an aqueous phase. If the components of the photosensitive resin composition have low solubility in the developing solution, when the developing process is repeated, insoluble components that decrease dispersibility in the developing solution greatly increase to form agglomerates (sludge), and when the developing process continues, the agglomerates It may re-attach to the substrate and cause a short circuit, and the piping of the developing tank may be clogged.

HABI 및 그 유도체를 광개시제로 사용하는 종래의 감광성 수지 조성물은, 레지스트 패턴 형성 시, 고감광도, 고용해도, 적은 현상 슬러지(sludge) 등의 장점을 함께 갖지 못한다는 단점에 대해서, 본 발명의 목적은, 우선 HABI계 혼합 광개시제를 제공하는 것이다. The conventional photosensitive resin composition using HABI and its derivatives as a photoinitiator does not have the advantages of high photosensitivity, solubility in solubility, and low development sludge when forming a resist pattern, and the object of the present invention is to , First of all, to provide a HABI-based mixed photoinitiator.

본 발명의 헥사아릴비스이미다졸계 혼합 광개시제는, 일반식 (I)과 같이 표시되는 구조를 가지며, 여기서, 4개의 연결위치 1'-2, 2-3', 1-2', 2'-3의 비스이미다졸 화합물을 포함하고, 상기 4개의 연결위치의 비스이미다졸 화합물의 혼합 광개시제 내 총 질량 백분율 함량은 92% 이상이다.The hexaarylbisimidazole-based mixed photoinitiator of the present invention has a structure represented by general formula (I), wherein the four linking positions 1'-2, 2-3', 1-2', 2'- Including the biimidazole compound of 3, the total mass percentage content in the mixed photoinitiator of the biimidazole compound at the 4 linking positions is 92% or more.

.

상기 치환된 아릴기는, 일치환 또는 다치환 될 수 있다. The substituted aryl group may be monosubstituted or polysubstituted.

바람직하게는, 아릴기의 치환기는 할로겐, 니트로기, 시아노기, 아미노기, 히드록시기, C1-C20의 알킬기 또는 알케닐기, C1-C8의 알콕시기 일 수 있으며, 여기서, 각각의 독립 변수(즉, 각 치환기) 중 메틸렌기는 산소, 황, 이미노기로 선택적으로 치환될 수 있다.Preferably, the substituent of the aryl group may be a halogen, a nitro group, a cyano group, an amino group, a hydroxy group, a C 1 -C 20 alkyl or alkenyl group, or a C 1 -C 8 alkoxy group, wherein each independent variable (ie, each substituent), the methylene group may be optionally substituted with an oxygen, sulfur, or imino group.

보다 바람직하게는, 아릴기의 치환기는 불소, 염소, 브롬, 니트로기, 시아노기, 아미노기, 히드록시기, C1-C10의 알킬기 또는 알케닐기, C1-C5의 알콕시기 일 수 있으며, 여기서, 각각의 독립 변수 중 메틸렌기는 산소, 황, 이미노기로 선택적으로 치환될 수 있다. More preferably, the substituent of the aryl group may be fluorine, chlorine, bromine, nitro group, cyano group, amino group, hydroxy group, C 1 -C 10 alkyl or alkenyl group, C 1 -C 5 alkoxy group, wherein , The methylene group of each independent variable may be optionally substituted with an oxygen, sulfur, or imino group.

보다 더 바람직하게는, Ar1, Ar2, Ar3, Ar4, Ar5, Ar6 중 적어도 하나 이상은 할로겐 치환기를 포함하는 아릴기이다. 할로겐 치환기는 경화 과정중의 변색 효과를 향상시켜 현상 시 전자 눈(electronic eye)의 인식 능력(비고: 감광성 수지층은 노광을 거친 후 색 변화가 발생해 비노광 영역과의 색 차이가 형성됨으로써 전자 눈에 의해 인식되는데, 본 발명은 색 차이를 더 명확하게 할 수 있다)을 향상시킴으로써 응용 제품의 품질을 향상시킨다. 특히 바람직하게는, 할로겐 치환기는 염소이다. Even more preferably, at least one of Ar 1 , Ar 2 , Ar 3 , Ar 4 , Ar 5 , and Ar 6 is an aryl group containing a halogen substituent. The halogen substituent enhances the discoloration effect during the curing process, and the recognition ability of the electronic eye during development (Note: The photosensitive resin layer undergoes exposure and then changes color, forming a color difference from the unexposed area, thereby perceived by the eye, the present invention can make color differences more distinct), thereby improving the quality of the applied product. Particularly preferably, the halogen substituent is chlorine.

본원에 기술되는 HABI는, 두 트리아릴이미다졸(아릴기의 치환기에 따라 동일하거나 상이할 수 있다)의 커플링에 의해 형성되는 헥사아릴비스이미다졸을 의미한다. 방향족 고리의 치환기의 유도 효과는 방향족 고리의 π전자 구름(electron cloud) 밀도를 감소시키기 때문에, 유도 효과는 방향족 고리의 왜곡을 촉진하고, 이미다졸 고리의 공액 중심의 편이를 유발해, 치환된 아릴을 이미다졸과 상이한 평면에 위치시켜(트리아릴이미다졸이 곡면상태를 형성한다) 최종적으로 두 이미다졸이 커플링하는 경우, N과 C의 연결로 상이한 공간 배열(configuration)이 발현되어 HABI의 성능에 큰 영향을 미치게 된다. HABI as described herein refers to a hexaarylbisimidazole formed by coupling of two triarylimidazoles (which may be the same or different depending on the substituents on the aryl groups). Since the inductive effect of the substituent on the aromatic ring reduces the π electron cloud density of the aromatic ring, the inductive effect promotes the distortion of the aromatic ring and causes the shift of the conjugate center of the imidazole ring, resulting in a substituted aryl When the two imidazoles are finally coupled by placing on a different plane from the imidazole (triarylimidazole forms a curved state), a different spatial configuration is expressed by the connection of N and C, resulting in HABI's It will have a big impact on performance.

본 발명의 감광성 수지 조성물에 있어서, 알칼리 가용성 중합체의 중량 평균 분자량은 특별히 제한되지 않으나, 기계적 강도 및 알칼리 현상성 측면에서 종합적으로 고려하여, 중량 평균 분자량은 바람직하게는, 15000-200000, 보다 바람직하게는, 30000-150000, 특히 바람직하게는, 30000-120000이다. 중량 평균 분자량이 15000을 초과는 경우, 노광 후 내현상액성이 추가로 향상되는 경향이 있으며, 상기 중량 평균 분자량이 200000 미만일 경우, 현상 시간이 더 짧아지는 경향이 있고 광개시제 등의 기타 성분과의 상용성을 유지할 수 있다. 알칼리 가용성 중합체의 중량 평균 분자량은 겔투과크로마토그래피(GPC, Gel Permeation Chromatography)로 측정하고, 표준 폴리스티렌의 표준 곡선(standard curve)을 이용한 환산을 통해 얻는다. In the photosensitive resin composition of the present invention, the weight average molecular weight of the alkali-soluble polymer is not particularly limited, but comprehensively considered in terms of mechanical strength and alkali developability, the weight average molecular weight is preferably 15000-200000, more preferably is 30000-150000, particularly preferably 30000-120000. When the weight average molecular weight is more than 15000, the post-exposure solution resistance tends to be further improved, and when the weight average molecular weight is less than 200000, the developing time tends to be shorter and compatibility with other components such as photoinitiators can keep the castle. The weight average molecular weight of the alkali-soluble polymer is measured by gel permeation chromatography (GPC) and obtained through conversion using a standard polystyrene standard curve.

또한, 우수한 알칼리 현상성 관점에서 고려하여, 알칼리 가용성 중합체의 산가는 바람직하게는, 50-300mgKOH/g, 보다 바람직하게는, 50-250mgKOH/g, 보다 더 바람직하게는, 70-250mgKOH/g, 특히 바람직하게는, 100-250mgKOH/g이다. 알칼리 가용성 수지의 산가가 50mgKOH/g 미만일 경우, 충분한 현상 속도를 확보하기 어렵고, 300mgKOH/g을 초과할 경우, 밀착성이 감소하고 패턴 단락이 발생하기 쉬우며, 조성물의 보관 안정성이 저하되고, 점도가 올라가는 문제가 용이하게 발생한다. Also, from the standpoint of excellent alkali developability, the acid value of the alkali-soluble polymer is preferably 50-300 mgKOH/g, more preferably 50-250 mgKOH/g, still more preferably 70-250 mgKOH/g, Especially preferably, it is 100-250 mgKOH/g. When the acid value of the alkali-soluble resin is less than 50 mgKOH/g, it is difficult to secure a sufficient development rate, and when it exceeds 300 mgKOH/g, adhesion is reduced and pattern short circuits are likely to occur, storage stability of the composition is lowered, and viscosity is reduced. The problem of going up easily arises.

알칼리 가용성 수지의 분자량 분포[중량 평균 분자량(Mw) / 수 평균 분자량(Mn)]는 바람직하게는, 1.5-6.0, 특히 바람직하게는 1.8-3.7이다. 분자량 분포가 상기 범위일 경우, 현상성이 우수한다.The molecular weight distribution [weight average molecular weight (Mw) / number average molecular weight (Mn)] of the alkali-soluble resin is preferably 1.5 to 6.0, particularly preferably 1.8 to 3.7. When the molecular weight distribution is within the above range, developability is excellent.

감광성 수지 조성물의 전체 100 질량부에서, 조성물 중 알칼리 가용성 중합체의 함량은 바람직하게는 20-70 질량부, 보다 바람직하게는 30-60 질량부이다. 알칼리 가용성 중합체의 함량이 20 질량부 이상일 경우, 감광성 수지 조성물의 도금 처리, 에칭 처리 등에 대한 내구성 향상을 확보할 수 있으며, 함량이 70 질량부 이하일 경우, 감광성 수지 조성물의 감도를 높이는데 유리하다.In total 100 parts by mass of the photosensitive resin composition, the content of the alkali-soluble polymer in the composition is preferably 20-70 parts by mass, more preferably 30-60 parts by mass. When the content of the alkali-soluble polymer is 20 parts by mass or more, it is possible to secure improved durability of the photosensitive resin composition for plating and etching, and when the content is 70 parts by mass or less, it is advantageous to increase the sensitivity of the photosensitive resin composition.

1. 헥사아릴비스이미다졸계 혼합 광개시제1. Hexaarylbisimidazole-based mixed photoinitiator

1.1 헥사아릴비스이미다졸계 혼합 광개시제 a1의 제조1.1 Preparation of hexaarylbisimidazole-based mixed photoinitiator a1

질소 분위기하에, 1L의 4구 플라스크에 2-(o-클로로페닐)-4,5-디페닐-이미다졸(M1, 2-(o-Chlorophenyl)-4,5-diphenyl-imidazole) 31.8g, 2,5-비스(o-클로로페닐)-4-(4,5-디메톡시페닐)-이미다졸(M2, 2,5-Bis(o-chlorophenyl)-4-(4,5-dimethoxyphenyl)-imidazole) 51.3g, 30% 액화 가성소다 4.2g, 테트라부틸암모늄 브로마이드(Tetrabutylammonium bromide) 4.0g, 톨루엔 300g을 투입하고, 가열 교반하여 60-65℃일 때 차아염소산나트륨(Sodium hypochlorite, 11%수용액) 85g을 적하하였다. 적하완료 후 보온 반응시키고, 샘플링을 M1과 M2가 모두 1% 미만으로 반응이 완료될 때까지 HPLC을 통해 제어하고, 보온을 종료하였다. Under a nitrogen atmosphere, 31.8 g of 2-(o-chlorophenyl)-4,5-diphenyl-imidazole (M1, 2-(o-Chlorophenyl)-4,5-diphenyl-imidazole) in a 1 L four-necked flask, 2,5-bis (o-chlorophenyl) -4- (4,5-dimethoxyphenyl) -imidazole (M2, 2,5-Bis (o-chlorophenyl) -4- (4,5-dimethoxyphenyl) - imidazole) 51.3g, 30% liquefied caustic soda 4.2g, tetrabutylammonium bromide 4.0g, and toluene 300g were added, heated and stirred to obtain sodium hypochlorite (11% aqueous solution) at 60-65°C. 85 g was added dropwise. After completion of the dropping, the warming reaction was performed, and sampling was controlled through HPLC until the reaction was completed with both M1 and M2 less than 1%, and the warming was terminated.

보온 반응 종료 후, 순수 100g으로 4회 세척하고, 이어서 톨루엔 20g으로 수층을 1회 추출한 다음, 유기층을 감압 증류하였다. 증류로 얻은 물질에 메탄올 70g을 첨가하여 용해액이 맑게 될 때까지 가열 교반하고, 이어서, 용해액을 메탄올 30g과 순수 50g으로 배합된 재결정 용액에 적하하고, 적하완료 후 여과, 린싱, 베이킹 건조하여 생성물 a1 79.1g을 수득하였다.After completion of the warming reaction, the mixture was washed 4 times with 100 g of pure water, then the aqueous layer was extracted once with 20 g of toluene, and the organic layer was distilled under reduced pressure. 70 g of methanol was added to the material obtained by distillation, and the solution was heated and stirred until the solution became clear, and then the solution was added dropwise to the recrystallized solution mixed with 30 g of methanol and 50 g of pure water. 79.1 g of product a1 was obtained.

생성물은 고성능 액체 크로마토그래피(HPLC)을 이용해 분석하였다.The product was analyzed using high performance liquid chromatography (HPLC).

도 1은 생성물 a1의 고성능 액체 크로마토그래피 그래프이다. 분석 결과는 4개의 연결위치 1'-2, 2-3', 1-2', 2'-3의 생성물의 피크 총 함량이 92.5%임을 보여준다. 1 is a high-performance liquid chromatography graph of product a1. The analysis results show that the total peak content of the products of the four linking positions 1'-2, 2-3', 1-2', and 2'-3 is 92.5%.

생성물 a1은 서로 다른 두 모노-이미다졸(즉, M1 및 M2)의 동종의 호모(homo) 커플링 및 크로스(cross) 커플링으로 얻어지는 혼합물로 T1, T2, T3를 포함한다. 생성물의 구조 조성을 정확히 검증하기 위해, 성분 a1-1, a1-2, a1-3에 대해 각각 검증분석을 수행하였다. Product a1 is a mixture obtained by homogeneous homo-coupling and cross-coupling of two different mono-imidazoles (ie, M1 and M2), and includes T1, T2 and T3. In order to accurately verify the structural composition of the product, verification analysis was performed on components a1-1, a1-2, and a1-3, respectively.

모노-이미다졸의 호모 커플링, 컬럼크로마토크래피, 크로마토그래피 분리 등의 방법을 통해 순수한 T1, T2, T3를 각각 수득하고, 구조 확인을 각각 수행하였다. Pure T1, T2, and T3 were respectively obtained through homo-coupling of mono-imidazole, column chromatography, chromatographic separation, and the like, and structural confirmation was performed, respectively.

T1은 도 2를 참조하면 액상 중 피크가 하나만 존재하나, 단결정 회절에 의하면 2개의 피크 형상이 획득된다. 구조적 특성을 결합하면, 두 모노-이미다졸의 커플링에 의한 주요 생성물은, 그 중 한 이미다졸의 수소를 포함하는 N이 또 다른 이미다졸의 2위치의 C와 연결되어 형성되는 혼합물임을 확인할 수 있고, 이에 의해, T1의 구조는 본 발명에 기재된 2개의 연결위치 1-2' 및 2'-3 임을 알 수 있다. Referring to FIG. 2, T1 has only one peak in the liquid phase, but two peak shapes are obtained according to single crystal diffraction. Combining the structural properties, it can be confirmed that the main product of the coupling of two mono-imidazoles is a mixture formed by the N containing hydrogen of one of the imidazoles being linked to the C of the 2-position of the other imidazole. Thereby, it can be seen that the structure of T1 is the two linking positions 1-2' and 2'-3 described in the present invention.

T1을 합성하는 이미다졸인 M1은 대칭형 이미다졸에 속한다. 때문에 커플링으로 얻은 1-2', 2'-3의 극성은 유사하고 액상 분리가 어렵다. M1의 구조 대칭성으로 인해 호모 커플링으로 얻은 생성물의 구조 중 1-2'와 1'-2의 구조는 동일하고, 2'-3, 3-2'의 구조도 동일하다. 때문에 T1의 주요 구조는 두개의 연결위치 1-2'와 3-2'의 생성물로 구조식은 하기와 같이 표시되며, 각각 T1-1: 2,2'-비스(o-클로로페닐)-4,4',5,5'-테트라페닐-1,2'-디이미다졸(2,2'-Bis(o-chlorophenyl)-4,4',5,5'-tetraphenyl-1,2'-diimidazol) 및 T1-2: 2,2'-비스(o-클로로페닐)-4,4',5,5'-테트라페닐-2'-3-디이미다졸(2,2'-Bis(o-chlorophenyl)-4,4',5,5'-tetraphenyl-2'-3-diimidazol)이다. M1, the imidazole that synthesizes T1, belongs to the symmetric imidazole class. Therefore, the polarities of 1-2' and 2'-3 obtained by coupling are similar and liquid phase separation is difficult. Due to the structural symmetry of M1, the structures of 1-2' and 1'-2 of the products obtained by homo-coupling are the same, and the structures of 2'-3 and 3-2' are also the same. Therefore, the main structure of T1 is a product of two linking positions 1-2' and 3-2', and the structural formula is represented as follows, respectively, T1-1: 2,2'-bis (o-chlorophenyl) -4, 4',5,5'-tetraphenyl-1,2'-diimidazol ) And T1-2: 2,2'-bis (o-chlorophenyl) -4,4', 5,5'-tetraphenyl-2'-3-diimidazole (2,2'-Bis (o- chlorophenyl) -4,4',5,5'-tetraphenyl-2'-3-diimidazol).

동일하게, 분리하여 얻은 순수한 T2를 분석하였다. 주요 구조는 4개의 연결위치의 생성물로 LCMS를 수행해 구조를 확인하였다. 849 및 850의 분자 조각 피크(fragment peak)는 질량 분석 보조기에 구비된 소프트웨어를 통해 얻었으며, 생성물의 분자량은 848로 T+1 및 T+2에 부합되었다. 이는 4개의 생성물이 구조가 유사하고, 분자량이 동일함을 증명한다. T2를 합성하는 모노-이미다졸인 M2는 비대칭 모노-이미다졸에 속하며, M2-1 및 M2-2의 두개의 구조가 존재하고, 아래와 같이 표시된다: Similarly, pure T2 obtained by separation was analyzed. The main structure was confirmed by performing LCMS as a product of four linkages. Molecular fragment peaks of 849 and 850 were obtained through the software provided in the mass spectrometer, and the molecular weight of the product was 848, which corresponded to T+1 and T+2. This proves that the four products are similar in structure and identical in molecular weight. M2, the mono-imidazole synthesizing T2, belongs to an asymmetric mono-imidazole, and has two structures, M2-1 and M2-2, and is represented as follows:

Figure 112021087199641-pct00021
Figure 112021087199641-pct00021

T2는 비대칭 모노-이미다졸의 커플링에 의해 합성되고, 이론적으로는 1-2 및 2-3의 연결위치에 연결되는 8개의 주요 구조가 존재하나, 호모 커플링된 모노-이미다졸의 경우는, 구조 중 1-2'와 1'-2의 구조가 동일하고, 2'-3과 3-2'의 구조도 동일하기 때문에 T2는 실제로 1-2 및 2-3의 연결위치에 연결되는 4개의 주요 구조가 존재하고, 그 조성은 각각 다음과 같다: T2 is synthesized by asymmetric mono-imidazole coupling, and theoretically, there are 8 main structures connected to the linking positions of 1-2 and 2-3, but in the case of homo-coupled mono-imidazole , Since the structures of 1-2' and 1'-2 are the same, and the structures of 2'-3 and 3-2' are also the same, T2 is actually connected to the connection position of 1-2 and 2-3. There are two main structures, the composition of which is respectively:

T2-1: 2,2',5,5'-테트라(o-클로로페닐)-4,4'-비스(3,4-디메톡시페닐)-2'-3-디이미다졸(2,2',5,5'-Tetra(o-chlorophenyl)-4,4'-bis(3,4-dimethoxyphenyl)-2',3-diimidazole), T2-2: 2,2',4,5'-테트라(o-클로로페닐)-4',5-비스(3,4-디메톡시페닐)-1-2'-디이미다졸(2,2',4,5'-Tetra(o-chlorophenyl)-4',5-bis(3,4-dimethoxyphenyl)-1-2'-diimidazole), T2-3: 2,2',5,5'-테트라(o-클로로페닐)-4,4'-비스(3,4-디메톡시페닐)-1-2'-디이미다졸(2,2',5,5'-Tetra(o-chlorophenyl)-4,4'-bis(3,4-dimethoxyphenyl)-1-2'-diimidazole), T2-4: 2,2',4,5'-테트라(o-클로로페닐)-4',5-비스(3,4-디메톡시페닐)-2'-3-디이미다졸(2,2',4,5'-Tetra(o-chlorophenyl)-4',5-bis(3,4-dimethoxyphenyl)-2',3-diimidazole), 구조는 아래와 같이 표시된다: T2-1: 2,2',5,5'-tetra (o-chlorophenyl) -4,4'-bis (3,4-dimethoxyphenyl) -2'-3-diimidazole (2,2 ',5,5'-Tetra(o-chlorophenyl)-4,4'-bis(3,4-dimethoxyphenyl)-2',3-diimidazole), T2-2: 2,2',4,5'- Tetra (o-chlorophenyl) -4 ', 5-bis (3,4-dimethoxyphenyl) -1-2'-diimidazole (2,2', 4,5'-Tetra (o-chlorophenyl) - 4',5-bis(3,4-dimethoxyphenyl)-1-2'-diimidazole), T2-3: 2,2',5,5'-tetra(o-chlorophenyl)-4,4'-bis (3,4-dimethoxyphenyl)-1-2'-diimidazole (2,2',5,5'-Tetra(o-chlorophenyl)-4,4'-bis(3,4-dimethoxyphenyl)- 1-2'-diimidazole), T2-4: 2,2',4,5'-tetra(o-chlorophenyl)-4',5-bis(3,4-dimethoxyphenyl)-2'-3 -Diimidazole (2,2',4,5'-Tetra(o-chlorophenyl)-4',5-bis(3,4-dimethoxyphenyl)-2',3-diimidazole), the structure is shown below :

T3는 M1과 M2의 커플링에 의해 형성되고, 분리하여 얻은 순수한 T3의 액상 내 주요 구조는 4개의 연결위치의 생성물로 LCMS를 수행해 4개의 연결위치의 생성물 구조를 확인하였다. 755 및 756의 분자 조각 피크(fragment peak)는 질량 분석 보조기에 구비된 소프트웨어를 통해 얻었으며, 생성물의 분자량은 754로 T+1 및 T+2에 부합되었다. 이는 4개의 생성물이 구조가 유사하고, 분자량이 동일함을 증명한다. T3는 대칭 이미다졸 M1과 비대칭 이미다졸 M2의 커플링에 의해 형성되고, 1-2 및 2-3의 연결위치에 연결되는 4개의 주요 구조가 존재하며, 그 조성은 각각 다음과 같다: T3 was formed by the coupling of M1 and M2, and the main structure in the liquid phase of pure T3 obtained by separation was a product of four linkages, and LCMS was performed to confirm the structure of the product of four linkages. Molecular fragment peaks of 755 and 756 were obtained through the software provided in the mass spectrometer, and the molecular weight of the product was 754, which corresponded to T+1 and T+2. This proves that the four products are similar in structure and identical in molecular weight. T3 is formed by the coupling of symmetric imidazole M1 and asymmetric imidazole M2, and there are four main structures connected to the linking positions of 1-2 and 2-3, the composition of which is as follows, respectively:

상기 표의 용해도 데이터는, 단일 구조의 순수한 HABI(a16 및 a17)는 용해도가 매우 열위하여 기타 HABI와 혼합(a14 및 a15)하더라도 용해도를 향상시킬 수 없고, 본 발명의 상기 HABI계 혼합 광개시제는 반드시 동일한 치환기의 구조로 동시에 4개의 연결위치가 존재해야 본 발명이 제시하는 최적의 용해도에 도달할 수 있음을 추가로 보여준다.The solubility data in the table above shows that single-structured pure HABIs (a16 and a17) have very poor solubility, so that the solubility cannot be improved even when mixed with other HABIs (a14 and a15), and the HABI-based mixed photoinitiator of the present invention is necessarily the same. It is further shown that the optimal solubility proposed by the present invention can be reached only when four linking positions are present at the same time in the structure of the substituent.

질소 분위기하에, 1L의 4구 플라스크에 2-(o-클로로페닐)-4,5-디페닐-이미다졸(M1, 2-(o-Chlorophenyl)-4,5-diphenyl-imidazole) 35g, 2-(2,4-디클로로페닐)-4.5-디페닐-이미다졸(M4, 2-(2,4-dichlorophenyl)-4,5-diphenyl-imidazole) 39g, 30% 액화 가성소다 5.6g, 테트라부틸암모늄 브로마이드 4.0g, 톨루엔 250g을 투입하고, 가열 교반하여 60-65℃일 때 차아염소산나트륨 87g을 적하하였다. 적하완료 후 보온 반응시키고, 샘플링을 M1과 M4가 모두 1% 미만으로 반응이 완료될 때까지 HPLC을 통해 제어하고, 보온을 종료하였다.Under a nitrogen atmosphere, 35 g of 2-(o-chlorophenyl)-4,5-diphenyl-imidazole (M1, 2-(o-Chlorophenyl)-4,5-diphenyl-imidazole) was placed in a 1 L four-necked flask, 2 -(2,4-dichlorophenyl)-4.5-diphenyl-imidazole (M4, 2-(2,4-dichlorophenyl)-4,5-diphenyl-imidazole) 39g, 30% liquefied caustic soda 5.6g, tetrabutyl 4.0 g of ammonium bromide and 250 g of toluene were added, heated and stirred, and 87 g of sodium hypochlorite was added dropwise at 60-65°C. After completion of the dropping, the warming reaction was performed, and sampling was controlled through HPLC until the reaction was completed with both M1 and M4 less than 1%, and the warming was terminated.

보온 반응 종료 후, 순수 100g으로 4회 세척하고, 이어서 톨루엔 20g으로 수층을 1회 추출한 다음, 유기층을 감압 증류하였다. 증류로 얻은 물질에 메탄올 60g을 첨가하여 용해액이 맑게 될 때까지 가열 교반하고, 이어서, 용해액을 메탄올 30g과 순수 50g으로 배합된 재결정 용액에 적하하고, 적하완료 후. 린싱, 건조, 베이킹하여 생성물 a21 66g을 수득하였다.After completion of the warming reaction, the mixture was washed 4 times with 100 g of pure water, then the aqueous layer was extracted once with 20 g of toluene, and the organic layer was distilled under reduced pressure. 60 g of methanol was added to the material obtained by distillation, the solution was heated and stirred until the solution became clear, and then the solution was added dropwise to a recrystallized solution blended with 30 g of methanol and 50 g of pure water, and the addition was completed. Rinsing, drying and baking gave 66 g of product a21.

분석 결과는 4개의 연결위치 1'-2, 2-3', 1-2', 2'-3의 생성물의 피크 총 함량이 92.1%임을 보여준다.The analysis results show that the total peak content of the products at the four linking positions 1'-2, 2-3', 1-2', and 2'-3 is 92.1%.

생성물 a21은 서로 다른 두 대칭형 모노-이미다졸(즉, M1 및 M4)의 동종의 호모(homo) 커플링 및 크로스(cross) 커플링으로 얻어지는 혼합물로 T1, T6, T7을 포함한다. 생성물의 구조 조성을 정확히 검증하기 위해, 성분 T1, T6, T7에 대해 각각 검증분석을 수행하였다.Product a21 is a mixture obtained by homogeneous homo-coupling and cross-coupling of two different symmetrical mono-imidazoles (i.e., M1 and M4), and includes T1, T6, and T7. In order to accurately verify the structural composition of the product, verification analysis was performed on components T1, T6, and T7, respectively.

모노-이미다졸의 호모 커플링, 컬럼크로마토크래피, 크로마토그래피 분리 등의 방법을 통해 T1, T6, T7을 각각 수득하고, 각각 구조 확인을 수행하였다.T1, T6, and T7 were respectively obtained through homo-coupling of mono-imidazole, column chromatography, chromatographic separation, and the like, and structural confirmation was performed.

T1는 화합물 a1과 구조가 일치한다.T1 has the same structure as compound a1.

T6은 2개의 구조를 갖지만 액상 중 피크는 하나만 존재하고, 구조의 조성은 T1과 유사하다. T6은 대칭형 이미다졸의 호모 커플링으로 얻어지기 때문에 커플링으로 얻은 1-2', 2'-3의 극성은 유사하고 액상 분리가 어렵다. 구조식은 하기와 같이 표시되며, 각각 다음과 같다: T6-1: 2,2'-비스(2,4-디클로로페닐)-4,4',5,5'-테트라페닐-1,2'-디이미다졸(2,2'-Bis(2,4-dichlorophenyl)-4,4',5,5'-tetraphenyl-1,2'-diimidazole), T6-2: 2,2'-비스(2,4-디클로로페닐)-4,4',5,5'-테트라페닐-2',3-디이미다졸(2,2'-Bis(2,4-dichlorophenyl)-4,4',5,5'-tetraphenyl-2',3-diimidazole);T6 has two structures, but only one peak exists in the liquid phase, and the composition of the structure is similar to that of T1. Since T6 is obtained by homo-coupling of symmetrical imidazole, polarities of 1-2' and 2'-3 obtained by coupling are similar and liquid phase separation is difficult. The structural formula is shown as follows, respectively: T6-1: 2,2'-bis(2,4-dichlorophenyl)-4,4',5,5'-tetraphenyl-1,2'- Diimidazole (2,2'-Bis(2,4-dichlorophenyl)-4,4',5,5'-tetraphenyl-1,2'-diimidazole), T6-2: 2,2'-bis(2 ,4-dichlorophenyl)-4,4',5,5'-tetraphenyl-2',3-diimidazole (2,2'-Bis(2,4-dichlorophenyl)-4,4',5, 5'-tetraphenyl-2',3-diimidazole);

Molecular fragment peaks of 729 and 730 were obtained through the software provided in the mass spectrometer, and the molecular weight of the product was 728, which corresponded to T+1 and T+2. This proves that the two products have similar peak structures and the same molecular weight.

T7는 대칭 M1와 대칭 M4의 커플링에 의해 형성되고, 1-2 및 2-3의 연결위치에 연결되는 4개의 주요 구조가 존재하며, 그 조성은 각각 다음과 같다:T7 is formed by the coupling of symmetric M1 and symmetric M4, and there are four main structures connected to the connecting positions of 1-2 and 2-3, the composition of which is as follows, respectively:

T7-1: 2-(2,4-디클로로페닐)-2'-(o-클로로페닐)-4,4',5,5'-테트라페닐-2,3'-디이미다졸(2-(2,4-Dichlorophenyl)-2'-(o-chlorophenyl)-4,4',5,5'-tetraphenyl-2,3'-diimidazole), T7-2: 2-(2,4-디클로로페닐)-2'-(o-클로로페닐)-4,4',5,5'-테트라페닐-1',2-디이미다졸(2-(2,4-Dichlorophenyl)-2'-(o-chlorophenyl)-4,4',5,5'-tetraphenyl-1',2-diimidazole), T7-3: 2-(2,4-디클로로페닐)-2'-(o-클로로페닐)-4,4',5,5'-테트라페닐-1,2'-디이미다졸(2-(2,4-Dichlorophenyl)-2'-(o-chlorophenyl)-4,4',5,5'-tetraphenyl-1,2'-diimidazole), T7-4: 2-(2,4-디클로로페닐)-2'-(o-클로로페닐)-4,4',5,5'-테트라페닐-2',3-디이미다졸(2-(2,4-Dichlorophenyl)-2'-(o-chlorophenyl)-4,4',5,5'-tetraphenyl-2',3-diimidazole), 구조식은 아래와 같이 표시된다:T7-1: 2-(2,4-dichlorophenyl)-2'-(o-chlorophenyl)-4,4',5,5'-tetraphenyl-2,3'-diimidazole (2-( 2,4-Dichlorophenyl)-2'-(o-chlorophenyl)-4,4',5,5'-tetraphenyl-2,3'-diimidazole), T7-2: 2-(2,4-dichlorophenyl) -2'-(o-chlorophenyl)-4,4',5,5'-tetraphenyl-1',2-diimidazole (2-(2,4-Dichlorophenyl)-2'-(o-chlorophenyl )-4,4',5,5'-tetraphenyl-1',2-diimidazole), T7-3: 2-(2,4-dichlorophenyl)-2'-(o-chlorophenyl)-4,4 ',5,5'-tetraphenyl-1,2'-diimidazole (2-(2,4-Dichlorophenyl)-2'-(o-chlorophenyl)-4,4',5,5'-tetraphenyl- 1,2'-diimidazole), T7-4: 2-(2,4-dichlorophenyl)-2'-(o-chlorophenyl)-4,4',5,5'-tetraphenyl-2',3 -Diimidazole (2-(2,4-Dichlorophenyl)-2'-(o-chlorophenyl)-4,4',5,5'-tetraphenyl-2',3-diimidazole), the structural formula is shown below :

분리하여 얻은 순수한 T7를 분석하고, LCMS를 수행해 구조를 확인하였다. 695 및 696의 분자 조각 피크(fragment peak)는 질량 분석 보조기에 구비된 소프트웨어를 통해 얻었으며, 생성물의 분자량은 694로 T+1 및 T+2에 부합되었다. 이는 4개의 생성물이 피크 구조가 유사하고, 분자량이 동일함을 증명한다.The isolated pure T7 was analyzed and the structure was confirmed by LCMS. Molecular fragment peaks of 695 and 696 were obtained through the software provided in the mass spectrometer, and the molecular weight of the product was 694, which corresponded to T+1 and T+2. This proves that the four products have similar peak structures and identical molecular weights.

질소 분위기하에, 1L의 4구 플라스크에 2-(o-클로로페닐)-4,5-디페닐-이미다졸(M1, 2-(o-Chlorophenyl)-4,5-diphenyl-imidazole) 35g, 2-(o-클로로 페닐)-4,5-비스(2-나프틸)-이미다졸(M5, 2-(o-chlorophenyl)-4,5-bis(2-naphthyl)-imidazole) 44g, 30%액화 가성소다5.6g, 테트라부틸암모늄 브로마이드 4.0g, 톨루엔 300g을 투입하고, 가열 교반하여 60-65℃일 때 차아염소산나트륨 97g을 적하하였다. 적하완료 후 보온 반응시키고, 샘플링을 M1과 M5가 모두 1% 미만으로 반응이 완료될 때까지 HPLC을 통해 제어하고, 보온을 종료하였다.Under a nitrogen atmosphere, 35 g of 2-(o-chlorophenyl)-4,5-diphenyl-imidazole (M1, 2-(o-Chlorophenyl)-4,5-diphenyl-imidazole) was placed in a 1 L four-necked flask, 2 -(o-chlorophenyl)-4,5-bis(2-naphthyl)-imidazole (M5, 2-(o-chlorophenyl)-4,5-bis(2-naphthyl)-imidazole) 44g, 30% 5.6 g of liquefied caustic soda, 4.0 g of tetrabutylammonium bromide, and 300 g of toluene were added, heated and stirred, and 97 g of sodium hypochlorite was added dropwise at 60-65°C. After completion of the dropping, the warming reaction was performed, and sampling was controlled through HPLC until the reaction was completed with both M1 and M5 less than 1%, and the warming was terminated.

보온 반응 종료 후, 순수 100g으로 4회 세척하고, 이어서 톨루엔 20g으로 수층을 1회 추출한 다음, 유기층을 감압 증류하였다. 증류로 얻은 물질에 메탄올 60g을 첨가하여 용해액이 맑게 될 때까지 가열 교반하고, 이어서, 용해액을 메탄올 30g과 순수 50g으로 배합된 재결정 용액에 적하하고, 적하완료 후. 린싱, 건조, 베이킹하여 생성물 a31 76g을 수득하였다.After completion of the warming reaction, the mixture was washed 4 times with 100 g of pure water, then the aqueous layer was extracted once with 20 g of toluene, and the organic layer was distilled under reduced pressure. 60 g of methanol was added to the material obtained by distillation, the solution was heated and stirred until the solution became clear, and then the solution was added dropwise to a recrystallized solution blended with 30 g of methanol and 50 g of pure water, and the addition was completed. Rinsing, drying and baking gave 76 g of product a31.

분석 결과는 4개의 연결위치 1'-2, 2-3', 1-2', 2'-3의 생성물의 피크 총 함량이 92.7%임을 보여준다.The analysis results show that the total peak content of the products at the four linking positions 1'-2, 2-3', 1-2', and 2'-3 is 92.7%.

생성물 a31은 서로 다른 두 대칭형 모노-이미다졸(즉, M1 및 M5)의 동종의 호모(homo) 커플링 및 크로스(cross) 커플링으로 얻어지는 혼합물로 T1, T8, T9를 포함한다. 생성물의 구조 조성을 정확히 검증하기 위해, 성분 T1, T8, T9에 대해 각각 검증분석을 수행하였다.Product a31 is a mixture obtained by homogeneous homo-coupling and cross-coupling of two different symmetrical mono-imidazoles (i.e., M1 and M5), and includes T1, T8, and T9. In order to accurately verify the structural composition of the product, verification analysis was performed on components T1, T8, and T9, respectively.

모노-이미다졸의 호모 커플링, 컬럼크로마토크래피, 크로마토그래피 분리 등의 방법을 통해 T1, T8, T9를 각각 수득하고, 각각 구조 확인을 수행하였다.T1, T8, and T9 were respectively obtained through homo-coupling of mono-imidazole, column chromatography, chromatographic separation, and the like, and structural confirmation was performed.

T1는 화합물 a1과 구조가 일치한다. T1 has the same structure as compound a1.

T8은 2개의 구조를 갖지만 액상 중 피크는 하나만 존재하고, 구조의 조성은 T1과 유사하다. T8은 대칭형 이미다졸(M5)의 호모 커플링으로 얻어지기 때문에 커플링으로 얻은 1-2', 2'-3의 극성은 유사하고 액상 분리가 어렵다. 구조식은 하기와 같이 표시되고, 각각 다음과 같다: T8-1: 2,2'-비스(o-클로로페닐)-4,4',5,5'-테트라(2-나프틸)-1,2'-디이미다졸(2,2'-Bis(o-chlorophenyl)-4,4',5,5'-tetra(2-naphthyl)-1,2'-diimidazole), T8-2: 2,2'-비스(o-클로로페닐)-4,4',5,5'-테트라(2-나프틸)-2',3- 디이미다졸(2,2'-Bis(o-chlorophenyl)-4,4',5,5'-tetra(2-naphthyl)-2',3-diimidazole);T8 has two structures, but only one peak exists in the liquid phase, and the composition of the structure is similar to that of T1. Since T8 is obtained by homo-coupling of symmetrical imidazole (M5), polarities of 1-2' and 2'-3 obtained by coupling are similar and liquid phase separation is difficult. The structural formula is shown as follows, respectively: T8-1: 2,2'-bis(o-chlorophenyl)-4,4',5,5'-tetra(2-naphthyl)-1, 2'-diimidazole (2,2'-Bis (o-chlorophenyl) -4,4', 5,5'-tetra (2-naphthyl) -1,2'-diimidazole), T8-2: 2, 2'-bis (o-chlorophenyl) -4,4', 5,5'-tetra (2-naphthyl) -2', 3-diimidazole (2,2'-Bis (o-chlorophenyl) - 4,4',5,5'-tetra(2-naphthyl)-2',3-diimidazole);
