    Abstract: A silicone overcoat (SOC) layer having a crosslinked polysiloxane composition comprising a perfluoropolyether segment are disclosed. The polysiloxane composition is the product of the hydrolysis and condensation of a SOC formulation comprising a perfluoropolyether compound, an aromatic silicon-containing compound, and a silicon-containing hole transport compound. An electrophotographic imaging member having such a SOC layer has improved properties.

    Abstract: Photoconductive imaging members comprise a symmetrical dimeric perylene as a charge generator, where the perylene is of formula (I): R = H, (cyclo)alkyl, oxa-alkyl, substituted alkyl, (substituted) aryl, or (substituted) aralkyl; and X = symmetrical bridging moiety, N-N when n is 0, (substituted) alkylene, cycloalkylene, (substituted) arylene or (substituted) aralkylene. Also claimed are: (i) a photoconductive imaging member (A); (ii) an imaging method comprising the formation of a latent image on the photoconductive imaging member; (iii) an imaging method comprising the formation of a latent image on the photoconductive imaging member (A); (iv) symmetrical perylenes (I); and (v) a process for the preparation of dimeric perylenes comprising reacting a perylene mono-imido anhydride with a symmetrical diamine.
