ABSTRACT:
A novel charge transport compound, a novel process using that novel compound and an organophotoreceptor includes:(a) a novel charge transport compound having the formulawhere R1and R2are selected so that R1and R2form, with the included nitrogen atom, a group selected from the group consisting of heterocyclic rings, aromatic rings, and dinaphthylamine; or R1comprises an aryl group and R2comprises a group selected from the group consisting of sulfolanyl, pyrrolyl, pyrazolyl, benzotriazolyl, stilbenyl, tetrazolyl, and group A, wherein group A is represented by the structureor R1comprises hydrogen, alkyl group, aryl group and R2comprises sulfonylphenyl.R3is hydrogen, alkyl group, aryl group, a heterocyclic group or a hydrocarbon group; andQ is a 3-carbazole group;(b) a charge generating compound; and(c) an electrically conductive substrate.
