Abstract
A compound having a structure, represented by the following general formula is useful as a light emitting material. At least one of R1 to R9 is a substituent; Y1 to Y3 each are a methylene group, a carbonyl group, a thiocarbonyl group, an imino group, an oxygen atom, a sulfur atom or a sulfonyl group; Z is a nitrogen atom, a boron atom or a phosphine oxide group.

A compound having a structure represented by the following general formula (1):
- wherein R1 to R9 each independently represent a hydrogen atom or a substituent, and at least one of R1 to R9 is a substituent;
- Y1 to Y3 each independently represent a substituted or unsubstituted methylene group (C(R10)(R11) where R10 and R11 each independently represent a hydrogen atom or a substituent), a carbonyl group (C═O), a thiocarbonyl group (C═S), a substituted or unsubstituted imino group (N(R12) where R12 represents a hydrogen atom or a substituent), an oxygen atom, a sulfur atom, or a sulfonyl group (SO2);
- Z represents a nitrogen atom, a boron atom, or a phosphine oxide group (P═O).
An organic light-emitting device containing a compound having a structure represented by the following general formula (1):
- wherein R1 to R9 each independently represent a hydrogen atom or a substituent, and at least one of R1 to R9 is a substituent;
- Y1 to Y3 each independently represent a substituted or unsubstituted methylene group (C(R10)(R11) where R10 and R11 each independently represent a hydrogen atom or a substituent), a carbonyl group (C═O), a thiocarbonyl group (C═S), a substituted or unsubstituted imino group (N(R12) where R12 represents a hydrogen atom or a substituent), an oxygen atom, a sulfur atom, or a sulfonyl group (SO2);
- Z represents a nitrogen atom, a boron atom, or a phosphine oxide group (P═O).
