摘要：
A compound having a structure represented by the following general formula emits delayed fluorescent light, and is useful as a light-emitting material. One or more of R1, R2, R3, R4, and R5 represent a 9-carbazolyl group having a substituent at at least one of 1-position and 8-position, or a 10-phenoxazyl group or 10-phenothiazyl group having a substituent at at least one of 1-position and 9-position. The balance thereof represents a hydrogen atom or a substituent.
