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<SUP>−4</SUP> cm<SUP>2</SUP> V<SUP>−1</SUP>s<SUP>−1</SUP> and in the compositions of the monomers with polymeric binder exceed 10<SUP>−6</SUP> cm<SUP>2</SUP> V<SUP>−1</SUP>s<SUP>−1</SUP> at an electric field of 10<SUP>6</SUP> V cm<SUP>−1</SUP> as characterized by the xerographic time of flight technique.
