摘要

A material for a light-emitting element is represented by a general formula (G1). In the general formula (G1), Ar1 represents a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, Ar2, Ar3, and Ar4 each independently represent a substituted or unsubstituted arylene group having 6 to 13 carbon atoms, R1 to R8 independently represent hydrogen or an alkyl group having 1 to 4 carbon atoms, R11 represents an alkyl group having 1 to 4 carbon atoms or a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, and R12 represents an alkyl group having 1 to 4 carbon atoms or a substituted or unsubstituted aryl group having 6 to 13 carbon atoms.
