Abstract: An aromatic silicon-containing compound has the formula: Ar-[X-L-SiR n(OR')3-n]m where Ar represents an aromatic group, X represents a divalent or trivalent group; L represents a divalent linking group; R represents a hydrogen atom, an alkyl group or an aryl group; R' represents an alkyl group having 1 to 5 carbon atoms; n is an integer of from 0 to 2; and m is an integer of from 1 to 5. The aromatic silicon- containing compound can be used in electrophotographic photoreceptors, particularly in outmost protective layers of such electrophotographic photoreceptors.

Abstract: Novel asymmetric arylamine compounds useful as hole transport molecules (HTMs) incorporated into imaging members, such as layered photoreceptor devices, and improved chemical processes for making the same. The arylamine compounds increase the charge mobility through the photoreceptor to effectuate an increase in machine speed. The chemical processes utilize a tandem Ullmann-Buchwald reaction sequence.
