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 4,4ʹ-thiobisbenzenethiol. The hole drift mobilities in the newly synthesized polymers exceed 10^-4 cm^2 V^-1s^-1 and in the compositions of the monomers with polymeric binder exceed 10^-6 cm^2 V^-1s^-1 at an electric field of 10^6 V cm^-1 as characterized by the xerographic time of flight technique.
