Synthesis and photoconductivity study of phthalocyanine polymers. VI. Ethylenediamine bridged polymeric MnPc

A novel polymer with quasi-one-dimensional structure of ethylenediamine bridged polymeric manganese phthalocyanine [PcMn(eda)]n was synthesized by complexing of manganese phthalocyanine (MnPc) and ethylenediamine (eda). The structure of the polymer was identified by infrared, ultraviolet–visible, and differential scanning calorimetric analysis. It was found that the polymer [PcMn(eda)]n showed much better photoconductive property than MnPc monomer when [PcMn(eda)]n or MnPc was used as the charge-generation material (CGM)-matched hydrazone charge-transportation material (CTM). Furthermore, the photoconductivities of [PcMn(eda)]n and MnPc were improved if the charge-generation layers (CGLs) were made by electric field poling. All these observations are ascribed to the effects of the one-dimensional molecular structure and the ordered material structure, respectively. © 1998 John Wiley & Sons, Inc. J. Appl. Polym.
