A light-emitting material containing a compound represented by the general formula (1) is capable of achieving an excellent external quantum efficiency on using in an organic light-emitting device. Rto Rrepresent a hydrogen atom or a substituent, provided that at least one of Rto Rrepresents a substituted or unsubstituted carbazolyl group; and Arto Arrepresent a substituted or unsubstituted aromatic ring or heteroaromatic ring. 

Light-emitting material, and delayed fluorescent emitter and organic light-emitting device using same

A compound represented by the general formula (1) is useful as a light-emitting material. R, R, and Reach represent a cyano group, or R, R, R, and Reach represent a cyano group; and the others of Rto Reach represent a group represented by any one of the following general formula (4), etc. 

Light-emitting material, organic light-emitting device, and compound

A compound represented by the general formula (1) is useful as a light-emitting material. In the general formula (1), Arto Areach represent a substituted or unsubstituted aryl group, provided that at least one of Arto Areach represent a carbazolyl group having an N-position substituted with a group containing an electron withdrawing group.
