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 Z1 and Z2 comprise, each independently, a bond, a vinyl group, a - CR1=N-NR2- group, or a -CR3=N-N=CR4- group; Y1 and Y2 comprise, each independently, an aromatic group; X1 and X2 are, each independently, a linking group; W1 and W2 are, each independently, a -(CH2)n- group or a -(CH2)n-1-C(=O)-group, where n is an integer between 1 and 10, inclusive; Q1 and Q2 are, each independently, O, S, or NR; and R1, R2, R3, R4, R, R', and R" comprise, each independently, H, an alkyl group, an alkenyl group, an alkynyl group, an acyl group, a heterocyclic group, or an aromatic group; and (b) a charge generating compound. <??>Corresponding electrophotographic apparatuses and imaging methods are described, as are charge transport materials and methods of preparing a bridged charge transport material.
