Zusammenfassung:The organic light-emitting element using the compound of the following general formula has excellent characteristics. Each of R1-R4 represents a hydrogen atom, a deuterium atom, an alkyl group, an aryl group or a donor group; two or more of R1-R4 represent a donor group and at least one of the R1-R4 represents a substituted ring-fused carbazol-9-yl group; x1 to X3 represent N or C (R); r represents a hydrogen atom, a deuterium atom or a substituent; each of Ar1 and Ar2 represents an aryl group; and L1 represents a single bond or a linking group. # imgabs0 # 使用了下述通式的化合物的有机发光元件的特性优异。R1～R4表示氢原子、氘原子、烷基、芳基或供体基团；R1～R4中的两个以上表示供体基团且其至少一个表示经取代的环稠合咔唑-9-基；X1～X3表示N或C(R)；R表示氢原子、氘原子或取代基；Ar1及Ar2表示芳基；L1表示单键或连接基团。#imgabs0#
