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

The present disclosure relates to compounds capable of emitting delayed fluorescence, and uses of the compounds in organic light-emitting diodes.

Composition of matter for use in organic light-emitting diodes

Using a compound represented by a general formula (A)m-L-(D)n, a light-emitting device having a high emission efficiency can be provided. L is an (m+n)-valent aromatic linking group; A is a group having a positive Hammett's σvalue; D is a group having a negative Hammett's σvalue; m is an integer of 1 or more; n is an integer of 2 or more. Two of plural D's differ in point of the substituent condition at specific aromatic rings.
