摘要：

Thin films of polypyrrole (PPy) containing tetrasulfonated metallophthalocyanine anions (MTsPc4-, M = Cu, Ni and Co) were prepared electrochemically from aqueous solution in a single-compartment cell. The films were deposited on a platinum anode and had thicknesses in the range 20-100-mu-m. Their room temperature electrical conductivities were of the order 1-10 S cm-1 and were compatible with a variable range hopping model of interchain charge transport between 77 and 300 K. The conductivities fell by approximately 50% when the films were exposed to laboratory air for one week; this reduction appears to be due to irreversible oxygen attack. ESR measurements suggested intercalation of the MTsPc anions between the PPy chains, while X-ray diffraction data indicated a level of structural order comparable with that of PPy-para-toluenesulfonate (PPyPTS).
