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"?where R is an (N,N-disubstituted)arylamine group;Q comprises an aliphatic or aromatic hydrazone linking group;n is 2; andY comprises a bridging group comprising an aryl group having the formula —Ar1-G-Ar2— where Ar1and Ar2are, each independently, an arylene group and G comprises a bond, O, S, —SO2—, an imine group, an alkylene group, or an aromatic group.
