Description

유기 화합물 및 이를 포함하는 유기 전계 발광 소자Organic compound and organic electroluminescent device comprising the same
본 발명은 신규한 유기 화합물 및 이를 포함한 유기 전계 발광 소자에 관한 것이다.The present invention relates to a novel organic compound and an organic electroluminescent device comprising the same.
유기 전계 발광 소자는 두 전극 사이에 전압을 걸어 주면 양극에서는 정공이, 음극에서는 전자가 유기물층으로 주입된다. 주입된 정공과 전자가 만났을 때 엑시톤(exciton)이 형성되며, 이 엑시톤이 바닥상태로 떨어질 때 빛이 나게 된다. 상기 유기물층으로 사용되는 물질은 그 기능에 따라, 발광 물질, 정공 주입 물질, 정공 수송 물질, 전자 수송 물질, 전자 주입 물질 등으로 분류될 수 있다.In the organic electroluminescent device, when a voltage is applied between two electrodes, holes are injected into the organic material layer from the anode and electrons from the cathode. When the injected holes and electrons meet, excitons are formed, and when the excitons fall to the ground, they shine. The material used as the organic material layer may be classified into a light emitting material, a hole injection material, a hole transport material, an electron transport material, an electron injection material and the like according to its function.
현재까지 정공 주입 물질, 정공 수송 물질. 정공 차단 물질, 전자 수송 물질로는 NPB, BCP, Alq3 등이 알려져 있고, 발광 물질로는 안트라센 유도체와, Firpic, Ir(ppy)3, (acac)Ir(btp)2 등과 같은 Ir을 포함하는 금속 착체 화합물 등이 알려져 있다.To date hole injection materials, hole transport materials. NPB, BCP, Alq 3 and the like are known as hole blocking materials and electron transport materials, and light emitting materials include anthracene derivatives and Ir such as Firpic, Ir (ppy) 3 and (acac) Ir (btp) 2 . Metal complex compounds and the like are known.
그러나 이러한 물질들은 유리전이온도가 낮고 열적 안정성이 좋지 않아 유기 전계 발광 소자의 수명 측면에서 만족할만한 수준이 되지 못하고 있다.However, these materials do not have a satisfactory level in terms of lifespan of the organic EL device because of low glass transition temperature and poor thermal stability.
본 발명은 유기 전계 발광 소자의 발광능을 높일 수 있는 신규 유기 화합물을 제공하는 것을 목적으로 한다.An object of the present invention is to provide a novel organic compound capable of increasing the light emitting ability of the organic electroluminescent device.
또한 본 발명은 상기 신규 유기 화합물을 포함하는 유기 전계 발광 소자를 제공하는 것도 목적으로 한다.Another object of the present invention is to provide an organic electroluminescent device comprising the novel organic compound.
상기 목적을 달성하기 위하여 본 발명은 하기 화학식 1로 표시되는 화합물을 제공한다.The present invention to achieve the above object provides a compound represented by the following formula (1).
