Abstract
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).
Claims25
A compound represented by the following general formula (1):
- wherein R1 to R5 each independently represent a hydrogen atom, a deuterium atom, or a substituent other than a cyano group, provided that at least one of R1 to R5 is a substituted or unsubstituted aryl group or a substituted or unsubstituted pyridyl group, at least two of R1 to R5 are donor groups, and at least one of the two or more donor groups is a substituted ring-fused indol-1-yl group in which the number of rings constituting the fused ring is 4 or more, and R1 and R2, R2 and R3, R3 and R4, or R4 and R5 may be bonded to each other to form a cyclic structure.
