Nusrallah Jubran, Zbigniew Tokarski, Kam Law, Vytautas Getautis, Jonas Sidaravicius, Osvaldas Paliulis, Valentas Gaidelis, Vygintas Jankauskas: Electrophotographic organophotoreceptors with novel charge transport compounds. Samsung Electronics, Patterson Thuente Skaar & Christensen P A, June 15, 2004: US06749978 (14 worldwide citation)

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, ...
