摘要： Derivatives of diiminoquinilidines are useful as electron transport agents in electrophotography. The diiminoquinilidine derivatives are inexpensive materials, requiring only two steps to synthesize, have excellent solubility and compatibility with most binders due to the presence of long alkyl chains, and evidence high electron mobility.

摘要： An inverse dual-layer organic photoconductor comprising a charge generation layer (CGL) formed on top of a charge transport layer (CTL), in turn formed on a substrate such as a web (drum) or subbing layer, is disclosed, in which the CGL includes a flexible polymer having a glass transition temperature (T.sub.g) of less than about 120.degree. C. as the binder for a charge generation species and in which the CTL includes a rigid polymer having a T.sub.g of greater than about 120.degree. C. as the binder for a charge transport species. The CTL is coated onto the substrate, using a non-chlorinated solvent. The CGL is coated onto the CTL, also using a non-chlorinated solvent, under conditions so as to form a diffused region at the boundary of the CGL and CTL. This type of photoconductor yields extremely low noise, exceptionally high-speed and excellent stable charging/discharging performance in the xerography process at room temperature and elevated temperature.
