ABSTRACT:
A quinoxaline derivative expressed by the general formula (1) is provided. (Each of R1to R12represents one of a hydrogen atom, a halogen atom, an alkyl group, an alkoxyl group, an acyl group, a dialkyl amino group, a diarylamino group, a substituted or unsubstituted vinyl group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heterocycle group. Ar1represents one of a substituted or unsubstituted biphenyl group and a substituted or unsubstituted terphenyl group, and Ar2represents one of a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted terphenyl group, and a substituted or unsubstituted monocyclic heterocycle group.)
