An organic light-emitting device containing both a compound represented by the following general formula (1) and a compound represented by the following general formula (2) has a high light emission efficiency. The rings a to c each are a benzene ring that can be optionally condensed, R1 and R2 each represent a substituted or unsubstituted aryl group, etc., four of R31 to R35 each are a substituted or unsubstituted carbazol-9-yl group, but all of these four are not the same, and the remaining one is a hydrogen atom, a cyano group, etc.
一种同时含有以下通式(1)和以下通式(2)所代表的化合物的有机发光器件具有很高的发光效率。其中,环 a 至 c 各为可选择缩合的苯环,R1 和 R2 各代表取代或未取代的芳基等,R31 至 R35 中的四个各为取代或未取代的
咔唑-9-基,但这四个不相同,其余一个为氢原子、
氰基等。
