Abstract
Improved methods for making hole transport molecules (HTMs) that are incorporated into imaging members, such as layered photoreceptor devices, to increase the photoreceptor's “hole mobility,” or its ability to move charge, across its charge transport layer (CTL). Embodiments pertain to a continuous process for making N,N-diphenyl-4-biphenylamine and a system for performing the same.
