A Novel Poly(Ferrocenyl-Schiff Base) and its Charge Transfer Complex with Iodine

A ferrocenyl Schiff base monomer was synthesized through the condensation of ferrocenecarboxaldehyde and phenylenediamine under neutral conditions, and then been used to produce copolymer materials with terephthaloyl chloride monomer by the Friedel-Crafts method. The model compound and copolymer of a novel poly(ferrocene-Schiff base) and their charge transfer complex with iodine was successful obtained, their structures been characterized by 1H-NMR spectra, infrared spectra, and ultraviolet spectra. In addition, the effects of iodine doping degree on its structure was studied, the electrical measurement results showed its conductivity can be increased several orders of magnitude after doping with iodine, the maximum conductivity at room temperature is 3.17×10-4 S•cm-1.
