  • Electrophotographic organophotoreceptors with novel charge transport compounds
    Publication number: 20030219662
    Abstract: Charge transport compounds are described that have a multiple number of hydrazone-bridged heterocyclic groups (especially julolidine groups, carbazole groups, triarylamine groups and (N,N-disubstituted)arylamine groups such as dialkarylamine groups (e.g. dimethylphenylamine; methylethylphenylamine, dipropylphenylamine, ethylepropylphenylamine, ethylbutylnaphthylamine, etc.), alkyldiarylamine groups (e.g. methyldiphenylamino, ethyldiphenylamino, etc), and triarylamino groups (e.g., triphenyl amino, trinaphthylamino, etc)) connected by a central bridging group.
