Polymers having a fluorene derivative, a homopolymer of 4-vinylbenzyl-9-dicyanomethylenefluorene-4-carboxylate and its copolymer with butyl acrylate or butyl methacrylate, were prepared as charge transport materials for electrophotography, and their electrical properties were measured. A monomer was prepared from 9-dicyanomethylenefluorene-4-carboxylic acid and 4-chloromethylstyrene. Polymerization was carried out using a radical initiator in a nitrogen atmosphere. These polymers were soluble in organic solvents such as THF, methylene chloride, chloroform, and DMF. All of the polymers showed two reversible redox potentials around −0.59 to −0.61 and −1.15 to −1.17 V versus Ag/AgCl electrode. The copolymers had high light sensitivities with a half-decay exposure of about 0.4 lux-s and a high electron drift mobility of 3.46 × 10⁻⁶ cm² Vs at the electric field of 4.27 × 10⁵ V/cm.
