Abstract
A compound represented by the general formula (1) is useful as a light-emitting material. In the general formula (1), from 0 to 1 of R3 to R5 represents a cyano group, from 1 to 5 of R1 to R5 represent a group represented by the general formula (2) etc., and the balance of R1 to R6 represent a hydrogen atom or a substituent other than above. R11 to R20 represent a hydrogen atom or a substituent, L12 represents a substituted or unsubstituted arylene group or a substituted or unsubstituted heteroarylene group.

A light-emitting material containing a compound represented by the following general formula (1):
- wherein in the general formula (1), from 0 to 1 of R1 to R5 represents a cyano group, from 2 to 5 of R1 to R5 each represent a group represented by the following general formula (2) or the following general formula (7), and the balance of R1 to R5 each represent a hydrogen atom or a substituent other than above, provided that when R1 is a group represented by the following general formula (2), then R5 is a hydrogen atom or a cyano group and that when R15 and R16 in the following general formula (2) are bonded to each other to form a single bond, one of R1 to R5 is a cyano group:
- wherein in the general formula (2), R11 to R20 each independently represent a hydrogen atom or a substituent, provided that R11 and R12, R12 and R13, R13 and R14, R14 and R15, R15 and R16, R16 and R17, R17 and R18, R18 and R19, and R19 and R20 each may be bonded to each other to form a cyclic structure;
- and L12 represents a substituted or unsubstituted arylene group or a substituted or unsubstituted heteroarylene group, provided that when R15 and R16 are not taken together to form a cyclic structure or R15 and R16 are taken together with an oxy group (—O—) to form a cyclic structure, then L12 is a monocyclic arylene or monocyclic heteroarylene group,
- wherein in the general formula (7), R71 to R79 each independently represent a hydrogen atom or a substituent, provided that R71 and R72, R72 and R73, R73 and R74, R74 and R75, R76 and R77, R77 and R78, R78 and R79 each may be bonded to each other to form a cyclic structure;
- and L17 represents a substituted or unsubstituted arylene group or a substituted or unsubstituted heteroarylene group.
