Description
본 발명은 유기 복수 종의 호스트 재료, 유기 전계 발광 화합물, 및 이를 포함하는 유기 전계 발광 소자에 관한 것이다.The present invention relates to multiple types of organic host materials, organic electroluminescent compounds, and organic electroluminescent devices containing the same.
이스트만 코닥 사의 Tang 등이 1987년에 발광층과 전하 전달층으로 이루어진 TPD/Alq3 이중층 저분자 녹색 유기 전계 발광 소자(OLED)를 처음으로 개발한 이후, 유기 전계 발광 소자에 대한 연구가 급속도로 빠르게 이루어져 현재 상용화에 이르렀다. 현재, 유기 전계 발광 소자는 패널 구현에 있어 발광 효율이 뛰어난 인광 물질을 주로 사용하고 있다. TV, 조명과 같은 많은 응용 분야에서, OLED 수명이 불충분하다는 문제점에 직면하고 있으며, OLED의 고효율이 여전히 요구된다. 일반적으로 OLED의 휘도가 높을수록, OLED의 수명은 단축된다. 따라서, 디스플레이의 장시간 사용과 높은 해상도를 위해서 높은 발광 효율 및/또는 장 수명을 갖는 OLED가 요구되고 있다. 발광 효율, 구동 전압 및/또는 수명을 개선시키기 위하여 유기 전계 발광 소자의 유기층에 여러 재료들 또는 컨셉들이 제안되어 왔으나, 현실적으로 사용하기에는 만족스럽지 못하였다.Since Eastman Kodak's Tang et al. first developed a TPD/Alq3 double-layer small molecule green organic electroluminescent device (OLED) consisting of a light-emitting layer and a charge transport layer in 1987, research on organic electroluminescent devices has progressed rapidly and is now commercialized. reached. Currently, organic electroluminescent devices mainly use phosphorescent materials with excellent luminous efficiency in panel implementation. In many application fields such as TV and lighting, the problem of insufficient OLED lifespan is faced, and high efficiency of OLED is still required. In general, the higher the luminance of an OLED, the shorter the lifespan of the OLED. Therefore, OLEDs with high luminous efficiency and/or long lifespan are required for long-term use and high resolution of displays. Various materials or concepts have been proposed for the organic layer of organic electroluminescent devices to improve luminous efficiency, driving voltage, and/or lifespan, but have not been satisfactory for practical use.

Additionally, there is a need to develop materials with improved performance, such as low driving voltage and/or high luminous efficiency characteristics, compared to the compounds disclosed in the patent document.
본원의 목적은, 구동 전압 및/또는 발광 효율이 개선된 유기 전계 발광 소자를 제공할 수 있는 개선된 복수 종의 호스트 재료를 제공하는 것이다. 본원의 다른 목적은, 유기 전계 발광 소자에 적용하기에 적합한 새로운 구조의 유기 전계 발광 화합물을 제공하는 것이다. 본원의 또 다른 목적은, 본원의 화합물 또는 특정 조합의 화합물을 포함함으로써, 구동 전압 및/또는 발광 효율이 개선된 유기 전계 발광 소자를 제공하는 것이다.The purpose of the present application is to provide a plurality of improved host materials that can provide an organic electroluminescent device with improved driving voltage and/or luminous efficiency. Another object of the present application is to provide an organic electroluminescent compound with a new structure suitable for application to organic electroluminescent devices.

또한, "오르토(ortho; o-)", "메타(meta; m-)", 및 "파라(para; p-)"는 각각 치환기의 상대적인 위치를 나타내는 접두어이다. 오르토(ortho)는 2개의 치환기가 서로 이웃하는 것을 나타내고, 일 예로 벤젠 치환체에서 치환기가 1, 2 위치에 있을 때, 오르토 위치라고 한다. 메타(meta)는 2개의 치환기가 1, 3 위치에 있는 것을 나타내며, 일 예로 벤젠 치환체에서 치환기가 1, 3 위치에 있을 때 메타 위치라고 한다. 파라(para)는 2개의 치환기가 1, 4 위치에 있는 것을 나타내며, 일 예로 벤젠 치환체에서 치환기가 1, 4 위치에 있을 때 파라 위치라고 한다.Additionally, “ortho (o-)”, “meta (m-)”, and “para (p-)” are prefixes that indicate the relative positions of substituents, respectively. Ortho indicates that two substituents are adjacent to each other. For example, when the substituents are in the 1st and 2nd positions in a benzene substituent, it is called the ortho position. Meta indicates that two substituents are at the 1st and 3rd positions. For example, in a benzene substituent, when the substituents are at the 1st and 3rd positions, it is called a meta position. Para indicates that two substituents are at the 1 and 4 positions. For example, in a benzene substituent, when the substituents are at the 1 and 4 positions, it is called the para position.
