An improved organophotoreceptor comprises an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising:n (a) a charge transport material having the formula nn n n n n n n n n n n n where X and X′ are, each independently, a linking group; n Ar comprises an aromatic group; n R 1 , R 2 , and R 3 comprise, each independently, H, an alkyl group, an alkenyl group, an alkynyl group, an aromatic group, or a heterocyclic group; and n E 1 and E 2 are, each independently, a reactive ring group; and n (b) a charge generating compound. n n n n n Corresponding electrophotographic apparatuses, imaging methods, and a polymeric charge transport material prepared from the charge transport material above are described. |
