| 摘要 |
The present invention provides organophotoreceptors having an electrically conductive substrate and photoconductive element on the electrically conductive substrate, the photoconductive element having a) a polymeric charge transport composition with the formula €ƒ€ƒ€ƒ
where Y 1 and Y 2 are, each independently, a bond, a -CR 1 =N-NR 2 - group, or a -CR 3 =N-N=CR 4 - group;
R, R', R", R 1 , R 2 , R 3 , and R 4 comprise, each independently, H, an alkyl group, an alkenyl group, a heterocyclic group, an aromatic group, or a part of a ring group;
X 1 and X 2 are, each independently, a linking group;
T 2 comprises a thiiranyl group, H, an alkyl group, an alkenyl group, or an aromatic group;
Ar comprises an aromatic group;
Z is a bridging group; and
n is a distribution of integers between 1 and 100,000 with an average value at least 2; and (b) a charge generating compound. Corresponding electrophotographic apparatuses and imaging processes are also described, as are polymeric charge transport compositions.
