[산업상 이용분야][Industrial use]
본 발명은 높은 융점을 나타내며, 형광성을 갖는 신규의 유기금속착물과 이를 이용한 유기발광소자에 관한 것이다.The present invention relates to a novel organometallic complex having a high melting point and having fluorescence and an organic light emitting device using the same.
[종래 기술][Prior art]
유기발광소자(organic electroluminescent device)는 대표적으로 양극층(anode), 정공이송층(hole transporting layer), 유기발광층(organic electrouminescent layer), 전자이송층(electron transporting layer), 음극층(cathode)로 구성되어 있다.An organic electroluminescent device is typically composed of an anode, a hole transporting layer, an organic electrouminescent layer, an electron transporting layer, and a cathode layer. It is.
초기의 유기발광소자는 전자이송, 유기발광 및 정공이송 기능을 갖는 유기물질로 구성된 단층(single layer) 유기발광 구조를 갖고 있어서 효율이 낮고, 구동전압이 높은 단점이 있었다.Early organic light emitting devices have a single layer organic light emitting structure composed of organic materials having electron transport, organic light emission, and hole transport functions, and thus have low efficiency and high driving voltage.
상기 단점을 보완하여 미국특허 제4,359,507호 등에서는 음극과 양극 사이에 전자이송층과 정공이송층을 갖는 2층 구조를 사용하여 발광효율을 높이고 구동전압을 낮출 수 있었다. 상기 유기 발광소자는 트리페닐아민 유도체(triphenyl amine derivative) 물질을 정공이송물질로 사용하고, 8-히드록시퀴놀린 알루미늄 착물(8-hydroxyquinoline aluminium complex)을 전자이송과 동시에 발광을 하는 물질로 사용한 것이다.In order to compensate for the above disadvantages, U.S. Patent No. 4,359,507 et al. Used a two-layer structure having an electron transport layer and a hole transport layer between the cathode and the anode to increase the luminous efficiency and lower the driving voltage. The organic light emitting device uses a triphenyl amine derivative as a hole transporting material, and uses an 8-hydroxyquinoline aluminum complex as a material to emit light simultaneously with electron transport.
미국특허 제4,539,507호 등에서는 양극과 정공이송 물질 간에 프탈로시아닌계 금속 착물(phthalocyanine metal complex)을 사용한 정공주입 물질을 도입하여 유기발광소자 수명과 구동 효율을 높였다.US Patent No. 4,539,507 and the like introduced a hole injection material using a phthalocyanine metal complex (phthalocyanine metal complex) between the positive electrode and the hole transport material to increase the lifetime and driving efficiency of the organic light emitting device.
유기 발광소자의 구동 중에서 나타나는 열적파괴(thermal breakdown) 현상은 유기 발광소자 성능에 있어서 중요한 문제점을 발생시키므로 열적으로 보다 더 안정한 재료가 요구된다.The thermal breakdown phenomenon during driving of the organic light emitting device generates an important problem in the performance of the organic light emitting device, and therefore, a more thermally stable material is required.
이러한 관점에서 융점이 높은 동시에 정공에 대하여 안정하며, 정공의 이동성(mobility)이 상대적으로 높은 트리페닐아민 유도체가 정공이송물질로 사용되었으며, 그예는 미국특허 제5,554,450호에 제안된 4,4'-비스[N-(1-나프틸-아미노]비페닐(4,4'-bis[N-(1-naphthyl)-N-phenyl-amino]biphenyl(α-NPD) 구조가 대표적이다.In view of this, triphenylamine derivatives having high melting point and stable hole and relatively high hole mobility were used as hole transporting materials, for example, 4,4'- proposed in US Pat. No. 5,554,450. A bis [N- (1-naphthyl-amino] biphenyl (4,4'-bis [N- (1-naphthyl) -N-phenyl-amino] biphenyl (α-NPD) structure is representative.
또한 일본 공개 특허 공보 평1-77252호에는 열적 안정성을 향상시킨 새로운 트리페닐아민 유도체가 정공이송 물질로 사용된 것이 기재되어 있다.In addition, Japanese Laid-Open Patent Publication No. Hei 1-77252 discloses that a new triphenylamine derivative having improved thermal stability is used as a hole transport material.
따라서 본 발명에서는 청색에 해당하는 대역 간극(band gap)을 갖고, 융점이 높아서 발광소자에 적용시 열적 안정성을 향상시킬 수 있는 신규의 착화합물과 그의 제조 방법을 제공하고자 하는 것이 목적이다.Accordingly, an object of the present invention is to provide a novel complex compound having a band gap corresponding to blue and a high melting point, which can improve thermal stability when applied to a light emitting device, and a method of manufacturing the same.
또 하나의 목적은 상기 신규의 착화합물을 적용한 유기 발광소자 및 그의 제조 방법을 제공하는 것이다.Another object is to provide an organic light emitting device to which the novel complex compound is applied and a method of manufacturing the same.

투명전극 위에 프탈로시아닌구리착물(copperphthalocyanine)을 200 Å의 두께로 열증착한 다음, 정공이송물질로서 실시예 4의 화학식 1b로 표시되는 화합물을200 Å의 두께로 증착하고, 그 위에 5 % 농도의 루브렌(rubrene)을 화학식 1b로 표시되는 화합물과 동시에 증착하여 200 Å 두께의 정공이송 및 발광을 동시에 하는 층을 형성시켰다. 그 위에 전자를 이송시키는 8-히드로시퀴놀린알루미늄착물(8-hydroxyquinoline aluminum complex)을 전자 이송층으로 500 Å의 두께로 증착시켰다.Phthalocyanine complex (copperphthalocyanine) on the transparent electrode was thermally evaporated to a thickness of 200 kPa, and then a compound represented by the formula (1b) of Example 4 as a hole transporting material was deposited to a thickness of 200 kPa, thereon 5% concentration of rubrene (rubrene) was deposited at the same time with the compound represented by the formula (1b) to form a layer to simultaneously perform hole transport and light emission of 200 Å thickness. The 8-hydroxyquinoline aluminum complex (8-hydroxyquinoline aluminum complex) for transporting electrons was deposited on the electron transport layer to a thickness of 500 kPa.
상기 전자이송층 위에 0.5 ㎚ 두께의 리튬플루오라이드(LiF)와 130 ㎚ 두께의 알루미늄을 순차적으로 증착하여 음극층을 형성시켰다.0.5 nm thick lithium fluoride (LiF) and 130 nm thick aluminum were sequentially deposited on the electron transport layer to form a cathode layer.
이렇게 제조된 발광소자는 7.2 V의 순 방향 전계를 가하였을 때 577 ㏅/㎡의 정공 이송층에 소량 도핑된 루브렌(rubrene)에서 기인하는 노란색 발광을 나타내었다.The light emitting device thus produced exhibited yellow light emission due to rubrene doped in a small amount of 577 ㏅ / m 2 when the forward electric field of 7.2 V was applied thereto.
본 실시예에 의하여 상기 화학식 1에서 선택되는 화합물이 정공이송과 동시에 발광층으로서의 역할을 할 수 있음을 알 수 있다.By the present embodiment it can be seen that the compound selected from Formula 1 can play a role as a light emitting layer at the same time as the hole transport.
본 발명의 신규한 유기 금속 착물은 융점이 높아서 정공이송층 또는 발광과 동시에 정공을 이송하는 층에 이 착물을 적용하여 제조된 유기 발광소자는 열적 안정성이 우수하다.The novel organometallic complex of the present invention has a high melting point, and thus an organic light emitting device manufactured by applying the complex to a hole transport layer or a layer for transporting holes simultaneously with light emission has excellent thermal stability.
