An ethylenediamine (eda)‐bridged iron phthalocyanine (FePc) polymer [PcFe(eda)] n was synthesized by the complexing of ethylenediamine and FePc. Through electric field poling, a novel low‐dimensional [PcFe(eda)] n ‐PVDF film was obtained. The characterization of the film by DSC, angle‐dependents XPS, FT‐IR Reflection Absorption Spectroscopy (FTIR‐RAS) revealed that the planes of phthalocyanine rings were parallel to the film surface. The photoconductivities of the photoreceptors (P/Rs) made from polarized or unpolarized [PcFe(eda)] n ‐PVDF film and different charge transfer materials were measued. It was found that the photoconductivities of P/Rs from [PcFe(eda)] n were much better than those of P/Rs from FePc, and after the orientation of electric field, the photoconductivities of P/Rs from [PcFe(eda)] n increased greatly. These changes were ascribed to the effects of the low dimension of the molecular and material structure. In ESR spectra, both the complexation of FePc and ethylenediamine and the polarization of electric field raised the charge carrier density, which suggesting that in low‐dimensional materials the intramolecular and intermolecular charge transfer interactions may increase significantly, resulting in the improvement of photoconductivities. © 1997 John Wiley & Sons, Inc.
