Abstract
A novel organic compound is provided. In addition, a novel organic compound with high heat resistance is provided. In the organic compound, a dibenzoquinoxaline skeleton and a 4,4-bidibenzofuran skeleton or a 4,4′-bidibezothiophene skeleton are connected to each other through an arylene group.
Claims21
An organic compound represented by General Formula (G1):
- wherein A represents a substituted or unsubstituted dibenzoquinoxaline skeleton,
- wherein B represents a substituted or unsubstituted 4,4′-bidibenzofuran skeleton or 4,4′-bidibenzothiophene skeleton,
- wherein Ar represents an arylene group having 6 to 13 carbon atoms,
- wherein n is an integer of 0 to 2,
- wherein the substituted or unsubstituted dibenzoquinoxaline skeleton is bonded to the arylene group having 6 to 13 carbon atoms at 2 position, and
- wherein the substituted or unsubstituted 4,4′-bidibenzofuran skeleton or 4,4′-bidibenzothiophene skeleton is bonded to the arylene group having 6 to 13 carbon atoms at 6 position.
