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