Novel Families of Hole-Transporting Monomers and Polymers

The novel families of hole transporting monomers and polymers containing hydrazone moieties are reported. The polymers were prepared in polyaddition reaction of hydrazone-containing diepoxides with 4,4′-thiobisbenzenethiol. The hole drift mobilities in the newly synthesized polymers exceed 10−4 cm2 V−1s−1 and in the compositions of the monomers with polymeric binder exceed 10−6 cm2 V−1s−1 at an electric field of 106 V cm−1 as characterized by the xerographic time of flight technique.
