Poly(azine)-based charge transport materials

摘要

An improved organophotoreceptor comprises 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 X₁ and X₂ are, each independently, a linking group; Ar comprises an aromatic group; R₁, R₂, and R₃ comprise, each independently, H, an alkyl group, an alkenyl group, an alkynyl group, an aromatic group, or a heterocyclic group; and n is a distribution of integers between 1 and 100,000 with an average value of greater than one; and (b) a charge generating compound. Corresponding electrophotographic apparatuses, imaging methods, and methods of forming the charge transport material are described.
