1. An organophotoreceptor 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
![]() where Y1 and Y2 are, each independently, an arylamine group;
R1 and R2 comprise, each independently, H, an alkyl group, an alkenyl group, a heterocyclic group, or an aromatic group;
X1 and X2, each independently, are bridging groups;
E1 and E2 are, each independently, an epoxy group; and
Z is a linking group comprising an alkyl group, an alkenyl group, a heterocyclic group, or an aromatic group; and
(b) a charge generating compound.
