ABSTRACT:
The present invention provides a quinoxaline derivative represented by a general formula (G1). In the formula, α1and α2each independently represent an arylene group which has 13 or less carbon atoms forming a ring; Ar represents an aryl group which has 13 or less carbon atoms forming a ring; R1and R6each independently represent any of a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or an aryl group which has 13 or less carbon atoms forming a ring; and R2to R5and R7to R10each independently represent any of a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, or a substituted or unsubstituted biphenyl group.
