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

Light-emitting material, compound, long-persistent phosphor and light-emitting element

An organic light emitting element produced by using a light emitting composition that contains both a first compound having a PBHT value more than 0.730 and a second compound having Elower than that of the first compound and ΔEless than 0.20 eV is excellent in durability. Eis the lowest excited singlet energy level, ΔEis the difference between the lowest excited singlet energy level and the lowest excited triplet energy level.
