US 5,475,137 A · M-phenylenediamine derivatives

Abstract

An electrophotographic photoconductor is composed of an electroconductive substrate and a photoconductive layer formed thereon including a m-phenylenediamine derivative of formula (I): ##STR1## wherein Ar represents a non-condensed polycyclic hydrocarbon group other than a phenyl group, or a condensed polycyclic hydrocarbon group having not more than 18 carbon atoms; and R.sup.1, R.sup.2, R.sup.3 and R.sup.4 each represent hydrogen, a halogen atom, a cyano group, a nitro group, an alkyl group, an alkoxyl group, an aryl group, an aryloxy group, an alkylmercapto group, a group represented by ##STR2## in which R.sup.6 and R.sup.7 each represent hydrogen, an alkyl group, or an aryl group, an alkylenedioxy group or an alkylenedithio group. Novel m-phenylenediamine derivatives for use in the electrophotoconductor and intermediates for producing the m-phenylenediamine derivatives, and methods of those derivatives are disclosed.

An N-phenyl-N-(3-diphenylaminophenyl)-1-pyrenyl-amine derivative of formula (II):

##STR53## wherein R.sup.8 and R.sup.9 each represent hydrogen, an alkyl group having 1 to 12 carbon atoms which is optionally substituted by a substituent selected from the group consisting of a phenyl group, a halogen atom, an alkoxyl group and an aryloxy group, an alkoxyl group having 1 to 12 carbon atoms which is optionally substituted by a substituent selected from the group consisting of a phenyl group, a halogen atom, an alkoxyl group and an aryloxy group, or a phenyl group which is optionally substituted by a substituent selected from the group consisting of an alkyl group having 1 to 8 carbon atoms, an alkoxyl group having 1 to 8 carbon atoms and a halogen atom.
