LIGHT-EMITTING MATERIAL, ORGANIC LIGHT-EMITTING DEVICE, AND COMPOUND

摘要

A compound represented by the following general formula (1) is useful as a light-emitting material. Y1 and Y2 each independently represent N or C(R7); and R1 to R7 each independently represent a hydrogen atom or a substituent, provided that at least one of R1 and R2, and at least one of R5 and R6 represent a group represented by the following general formula (2). Z represent a divalent linking group having a linking chain length of 1 atom; L1 represents a single bond or a substituted or unsubstituted arylene group; and R11 to R18 each independently represent a hydrogen atom or a substituent.;

1. A method for using a compound represented by the following general formula (1) as a light-emitting material:wherein in the general formula (1), Y1 and Y2 each independently represent N or C(R7); and R1 to R7 each independently represent a hydrogen atom or a substituent, provided that at least one of R1 and R2, and at least one of R5 and R6 each independently represent a group represented by the following general formula (2):wherein in the general formula (2), Z represent a divalent linking group having a linking chain length of 1 atom; L1 represents a single bond or a substituted or unsubstituted arylene group; * represents a position bonded to the heterocyclic ring in the general formula (1); and R11 to R18 each independently represent a hydrogen atom or a substituent, provided that R11 and R12, R12 and R13, R13 and R14, R15 and R16, R16 and R17, and R17 and R18 each may be bonded to each other to form a cyclic structure.
