Description

트리페닐렌계 화합물 및 이를 포함하는 유기 전계 발광 소자 {TRIPHENYLENE-BASED COMPOUNDS AND ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING SAME}Triphenylene-based compound and organic electroluminescent device including the same {TRIPHENYLENE-BASED COMPOUNDS AND ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING SAME}

본 발명은 전자 수송능, 정공 주입 및/또는 수송능, 및/또는 발광능이 우수한 신규의 트리페닐렌계 화합물 및 이를 하나 이상의 유기층에 포함함으로써 발광효율, 휘도, 열적 안정성, 구동 전압, 수명 등의 특성이 향상된 유기 전계 발광 소자에 관한 것이다.The present invention includes a novel triphenylene compound having excellent electron transporting ability, hole injection and / or transporting ability, and / or luminous ability, and including the same in at least one organic layer, such as luminous efficiency, luminance, thermal stability, driving voltage, and lifetime. This is an improved organic electroluminescent device.

유기 전계 발광(electroluminescent, EL) 소자(이하, 간단히 '유기 EL 소자'로 칭함)는 자발광 표시 소자이므로 명암비가 우수하고 시야각이 넓으며 응답시간이 빨라 고성능 디스플레이에 적합하다. Organic electroluminescent (EL) devices (hereinafter, simply referred to as 'organic EL devices') are self-luminous display devices, and thus have excellent contrast ratio, wide viewing angle, and fast response time, which are suitable for high performance displays.

1950년대 Bernanose의 유기 박막 발광 관측을 시점으로 1965년 안트라센 단결정을 이용한 청색 전기발광으로 이어진 유기 EL 소자에 대한 연구는 1987년 탕(Tang)에 의하여 정공층과 발광층의 기능층으로 나눈 적층구조의 유기 EL 소자가 제시 되었고, 고효율, 고수명의 유기 EL 소자를 만들기 위하여 소자 내 각각의 특징적인 유기물 층을 도입하는 형태로 발전하여 왔으며, 이에 사용되는 특화된 물질의 개발로 이어졌다. From the observation of organic thin-film emission by Bernanose in the 1950s, the study on organic EL devices that led to blue electroluminescence using anthracene single crystals in 1965 was carried out by Tang in 1987. The EL device has been proposed, and has been developed in the form of introducing each characteristic organic material layer in the device to make a high efficiency, high life organic EL device, and led to the development of specialized materials used therein.

유기 EL 소자를 효율적으로 만들기 위한 일 방법으로서 소자내의 유기층을 단층 대신 다층 구조로 제조하는 연구가 진행되어 왔다. As one method for making an organic EL device efficiently, research has been conducted to manufacture an organic layer in the device into a multilayer structure instead of a single layer.

일반적으로 유기 EL 소자는 기판 상부에 양극(anode)이 형성되어 있고 양극 상부에 순차적으로 정공 주입층, 정공 수송층, 발광층, 전자 수송층, 전자 주입층 및 음극(cathode)이 형성되어 있는 박막 다층 구조로 되어 있다. In general, an organic EL device has a thin film multilayer structure in which an anode is formed on a substrate and a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, and a cathode are sequentially formed on the anode. It is.

현재 사용되는 대부분의 유기 EL 소자는 기판, 양극, 양극으로 정공을 받아들이는 정공 주입층, 정공을 전달하는 정공 전달층, 정공과 전자가 재결합하여 빛을 내는 발광층, 전자를 전달하는 전자 전달층, 음극으로부터 전자를 받아들이는 전자 주입층 및 음극으로 이루어져 있다. 이렇게 유기 EL 소자를 다층으로 제작하는 이유는 정공과 전자의 이동속도가 상이하며, 따라서 적절한 정공 주입층 및 전달층, 전자 전달층 및 전자 주입층을 만들어 주면 정공과 전자가 효과적으로 전달 될 수 있으며, 소자 내 정공과 전자의 균형이 이루어져 발광 효율을 높일 수 있기 때문이다. Most organic EL devices currently used include a hole injection layer that receives holes into a substrate, an anode, and an anode, a hole transport layer that transfers holes, a light emitting layer that recombines holes and electrons to emit light, an electron transport layer that transfers electrons, It consists of an electron injection layer and a cathode which receive an electron from a cathode. The reason why the organic EL device is manufactured in multiple layers is that the movement speeds of the holes and the electrons are different. Therefore, the holes and the electrons can be effectively transferred by making the appropriate hole injection layer, the transfer layer, the electron transfer layer, and the electron injection layer. This is because the light emission efficiency can be improved by balancing holes and electrons in the device.

전자 주입층에서 주입된 전자와 정공 주입층에서 전달된 정공은 발광층에서 재결합하여 엑시톤을 형성하게 되며 일중항 여기상태에서 기저 상태로 떨어지며 발광 하는 것을 형광이라고 하고, 삼중항 여기상태에서 기저 상태로 떨어지는 발광을 인광이라고 한다. 이론적으로 캐리어가 발광층에서 재결합하여 엑시톤이 발생될 때 일중항과 삼중항 여기자의 비율이 1:3의 비율로 발생되게 되며, 인광을 이용할 경우 내부 양자 효율이 100%에 이를 수 있다. Electrons injected from the electron injection layer and holes transferred from the hole injection layer recombine in the light emitting layer to form excitons, and fall from the singlet excited state to the ground state and are called fluorescence, and fall from the triplet excited state to the ground state. Luminescence is called phosphorescence. Theoretically, when the exciton is generated when the carrier is recombined in the emission layer, the ratio of singlet and triplet excitons is generated at a ratio of 1: 3, and when phosphorescence is used, the internal quantum efficiency may be 100%.

일반적으로 인광 호스트 재료로는 CBP(4,4-dicarbazolybiphenyl)등의 카바졸 고리 화합물(KR 20077015570 등)이 사용되며, 인광 게스트 재료로는 Ir, Pt 등의 중원자(heavy atom)가 포함된 금속 착체 화합물(US 6830828 등)이 널리 보고되고 있다. In general, a carbazole ring compound such as CBP (4,4-dicarbazolybiphenyl) (KR 20077015570, etc.) is used as a phosphorescent host material, and a metal containing heavy atoms such as Ir and Pt as a phosphorescent guest material Complex compounds (US 6830828, etc.) have been widely reported.

하지만 현재 사용되고 있는 인광 호스트 재료인 CBP의 경우 유리전이온도(Tg)가 110℃ 정도로 낮으며, 소자 내의 결정화가 쉽게 일어나 유기 EL 소자의 수명이 150 시간 정도로 매우 짧은 문제점이 있다.However, CBP, which is currently used phosphorescent host material, has a low glass transition temperature (Tg) of about 110 ° C., and crystallization within the device is easy, resulting in a very short lifespan of about 150 hours.

따라서, 본 발명의 목적은 우수한 전자 수송능, 정공 주입 및/또는 수송능 및/또는 발광능(형광 또는 인광)을 가진 트리페닐렌계 화합물 및 이를 하나 이상의 유기층에 포함함으로써 발광효율, 휘도, 열적 안정성, 구동 전압, 수명 등의 특성이 향상된 유기 EL 소자를 제공하는 것이다.Accordingly, an object of the present invention is to provide a triphenylene-based compound having excellent electron transporting ability, hole injection and / or transporting ability, and / or light emitting ability (fluorescence or phosphorescence) and light emission efficiency, brightness, and thermal stability by including the same in at least one organic layer. To provide an organic EL device having improved characteristics such as driving voltage and lifetime.
