Abstract:
The present invention provides a quinoxaline derivative represented by a general formula (G1). In the formula, α1 and α2 each 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; R1 and R6 each 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 R2 to R5 and R7 to R10 each 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.
