Interaction of Сationic Porphyrin with Cobalt Tetracarboxyphthalocyaninate in a Solution

The preparation of a heterocomplex based on 5,10,15,20-tetrakis(1-hexylpyridinium-4-yl)porphine tetrabromide and cobalt tetracarboxyphthalocyaninate is described in the work.The porphyrin-phthalocyanine complex has been obtained by homogeneous and heterogeneous methods.The donor-acceptor nature of the interaction between macroheterocycles has been confirmed by electron spectroscopy and fluorescence.Carrying out a catalytic experiment in the oxidation reaction of 4-tert-butylpyrocatechol with atmospheric oxygen confirms the occurrence of the charge transfer process.The resulting complex is characterized by inhibition of the redox activity of cobalt phthalocyaninate in its composition.The acceptor nature of cobalt tetra-carboxyphthalocyaninate in relation to the cationic porphyrin in the heterocomplex is shown by quantum chemical modeling.
