Zusammenfassung:A compound represented by the following general formula is an excellent light-emitting material. R1 to R5 each independently represent a hydrogen atom or a substituent, and one of R1 to R5 is a cyano group, one to three of R1 to R5 each are an aryl group Ar optionally substituted with an alkyl group or an aryl group, and one to three of R1 to R5 each are a donor group D (but excepting one that corresponds to Ar).
