Azine-based charge transport materials

摘要

The present invention provides organophotoreceptors comprising an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising: (a) a charge transport material having the formula <CHEM> where X comprises a linking group; R1 and R1' comprise, each independently, H, an alkyl group, an alkenyl group, an alkynyl group, an aromatic group, or a heterocyclic group; and R2, R3, R2', and R3' comprise, each independently, an arylamine group; and (b) a charge generating compound. <??>Corresponding electrophotographic apparatuses, imaging methods (processes), and methods of forming the charge transport material are described, as are charge transport materials.
