  • Patent number: 7291431
    Abstract: This invention relates to a novel organophotoreceptor that comprises an electrically conductive substrate and photoconductive element on the electrically conductive substrate, the photoconductive element having a) a novel charge transport compound having the formula where X is a divalent hydrocarbon group of 1 to 30 carbon atoms, or a divalent hydrocarbon group of 1 to 30 carbon atoms where there is at least one substitution of a carbon atom by a heteroatom provided that no two heteroatoms may be adjacent within the backbone of an aliphatic divalent hydrocarbon radical, R1 is an aryl group or a heterocyclic group, R2 is a (N,N-disubstituted)arylamine group, and R3 is an epoxy group; and (b) a charge generating compound. The epoxy group can be reacted with a functional group within the polymer to form a polymeric charge transport compound either directly or through a crosslinking agent.

  • Patent number: 6899984
    Abstract: This invention relates to a novel organophotoreceptor that includes: (a) a charge transport compound having the formula where n is an integer from 0 to 1 inclusive; X is an (N,N-disubstituted)arylamine, such as a carbazole group, a julolidine group, or a p-(N,N-disubstituted)arylamine group (which can be a triarylamine, an alkyldiarylamine or a dialkylarylamine); Ar is an aryl group or a heterocyclic group; A is a linking group having the formula —S—(CH2)m—S— where m is an integer from 1 to 15 inclusive and; B is a second linking group with the formula —(CH2)p— which can be branched or linear, where p is an integer from 3 and 20 inclusive and where one or more methylene groups can be optionally replaced by O, S, a carbonyl group, urethane, urea, an ester group, a —NR21 group, a CHR22 group, or a CR23R24 group where R21, R22, R23 and R24 are, independently, H, hydroxyl, thiol, an amine group, an alkyl group, an alkaryl group, an aryl group, or part of a ring; (b) a charge generating compound; and (c)
