摘要： A compound represented by the following general formula is an excellent light emitting material. R1 to R5 each represent a hydrogen atom, a deuterium atom, or a substituent other than a cyano group, but one or more of R1 to R5 is an aryl group or a pyridyl group, two or more of R1 to R5 are donor groups, and one or more of them are a substituted ring-fused indol-1-yl group (the number of rings constituting the fused ring is 4 or more).
