The following general formulas (A) to (D); [Wherein, RA 1 and RA 2 are amino groups, RA 3 and RA 4 are lower alkyl groups, RA 5 and RA 6 are lower alkyl groups, and RA 7 and RA 8 are lower groups. In the alkyl group and the like, m and n each represent an integer of 0 to 6. ], [Wherein, RB 1 and RB 2 represent a lower alkyl group, RB 3 and RB 5 represent a halogen atom, and RB 4 represents a lower alkyl group, etc. ], [Wherein, RC 1 represents an electron-withdrawing group such as a halogen-substituted lower alkyl group, and RC 2 represents an electron-donating group such as an amino group which may have a lower alkyl group. ], [Wherein, RD 1 , RD 2 , RD 3 and RD 4 represent a hydrogen atom or a halogen atom, and RD 5 represents a hydrogen atom or an alkyl group. ], And a benzene compound that emits light efficiently in a solid state. |
