| Zusammenfassung: | Provided are a hole transport material represented by chemical formula 1, and an organic electroluminescent element and an electronic device including the same. In the chemical formula, R is as defined in the specification. The hole transport material can easily be used to produce a long-term stable OLED element by having excellent external quantum efficiency and excellent light emitting efficiency, brightness, thermal stability, and element lifespan.
하기 화학식 1로 표시되는 정공 수송 물질, 이를 포함하는 유기전기발광소자 및 전자 기기를 제공한다. [화학식 1]상기 식에서 R은 명세서에서 정의한 바와 같다. 상기 정공 수송 물질은 외부 양자 효율이 뛰어나면서도 발광효율, 휘도, 열적 안정성 및 소자 수명이 뛰어나 장기적으로 안정한 OLED 소자를 생산하는데 용이하게 이용될 수 있다. |
