摘要：

Interaction between the anilinium cation and copper tetrasulfophthalocyanine anion (CuTSPc) was studied in an aqueous sulfuric acid solution using electronic absorption spectra. It was shown that up to 0.15 M aniline could be introduced into the solution at the dye concentration of 10(-3) M, after which a solid deposit of a complex (salt) between the anilinium cation and copper tetrasulfophthalocyanine anion started precipitating rapidly. The effect of the dye on the kinetics of aniline polymerization on conducting glasses and on the properties of the polymer obtained was studied. It was found that phthalocyanine accelerates electropolymerization of aniline and is immobilized within the polymer matrix. It was shown that the self-catalytic synthesis mechanism characteristic of polyaniline is also preserved in the case of the composite of polyaniline-copper tetrasulfophthalocyanine.
