ABSTRACT:
Charge transporting materials having general formula (I): ##STR1## wherein R.sup.1 represents hydrogen; an unsubstituted or substituted alkyl group; an alkoxyl group having 1 to 4 carbon atoms; a thioalkoxyl group having 1 to 4 carbon atoms; an aryloxy group; an aralkyl group; a nitro group; an unsubstituted or substituted aryl group; a halogen; an amino group; an unsubstituted or substituted dialkylamino group; R.sup.2 represents hydrogen; an unsubstituted or substituted alkyl group; an alkoxyl group having 1 to 4 carbon atoms; or a halogen; R.sup.3 represents hydrogen; an alkyl group having 1 to 4 carbon atoms; an alkoxyl group having 1 to 4 carbon atoms; a halogen; a dialkylamino group; an amino group; a thioalkoxyl group having 1 to 4 carbon atoms; an aryloxy group; a methylenedioxy group; an aralkyl group; or an unsubstituted or substituted aryl group; R.sup.4 represents hydrogen; an alkoxyl group; or a halogen; Ar represents an unsubstituted or substituted monocyclic hydrocarbon group, non-condensed polycyclic hydrocarbon group or heterocyclic group; k is an integer of 0 to 5, l is an integer of 0 to 4, and (p+m) is 0 to 5, provided that when Ar is an unsubstituted phenyl group, R.sup.1, R.sup.2, R.sup.3, and R.sup.4 cannot be hydrogen at the same time.
