Quinomethane compounds having a structure represented by the general formula (1):wherein R<1 >to R<4 >and R<9 >to R<12 >are the same or different and each represents a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, a cyclic alkyl group, an aryl group, or an alkoxy group having 1 to 6 carbon atoms; R<5 >and R<6 >are the same or different and each represents an alkyl group having 1 to 12 carbon atoms, an aryl group, or a heterocyclic group; R<7 >and R<8 >each represents a hydrogen atom; and optional substituents are each a halogen atom, an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, an aryl group, or a heterocyclic group. Since these compounds transport electrons efficiently, they are useful in electrophotographic photoreceptors and/or organic electroluminescence applications.
