Polymeric charge transport materials having repeating units comprising an aromatic group and a -S- linkage

摘要

Improved organophotoreceptor comprises an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising: (a) a polymeric charge transport material having the formula where n is a distribution of integers between 1 and 100,000 with an average value of greater than one; Y comprises an aromatic group; X₁ and X₂, each independently, is a bond or a linking group; Q₁ and Q₂ are, each independently, O, S, or NR; and R, R₁, and R₂ 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, imaging methods, and methods of preparing the polymeric charge transport material are described.
