New high effective catalysts of oxidation on the basis of the charged forms phthalocyanines


The influence of a charge sign of the substituents in phthalocyanines with the common formula R+8PcM and R-8PcM on their catalytic activity in ascorbic acid oxidation by dioxygen was investigated. On the example of complexes Fe and Co it was shown that the change of the charge sign of the substituents from negative to positive one results in increase of phthalocyanines catalytic activity on the order of magnitude. Opposite charged complexes form in solutions the stable associates. Composition and structure of the associates are determined by a nature of metal and the catalytic activity of some of them essentially higher than sum of activity for initial complexes.
