ABSTRACT:
Charge transport compounds are described that have a multiple number of hydrazone-bridged (N,N-disubstituted)arylamine groups connected by a central bridging group. Examples of charge transport compounds of this invention are those having the following generic formula:in-line-formulae description="In-line Formulae" end="lead"?(R-Q)n-Yin-line-formulae description="In-line Formulae" end="tail"?whereR is an (N,N-disubstituted)arylamine group;Q comprises an aromatic hydrazone linking group;Y comprises a bridging group between R-Q- groups; andn is an integer between 2 and 6.An organic photoreceptor includes (a) that compound and (b) a charge generating compound; and (c) an electrically conductive substrate.
