Аннотация
The problem about the role of the coordinated exobidentate ligand in the formation of dimeric structures of sulfonated cobalt phthalocyanine derivatives is considered. The size of the peripheral substituent of the macrocycle and remoteness of the ionogenic group from the macrocycle play the key role in the formation of dimers of a specified type. As the extension of the peripheral substituent of the macrocycle increases, the stability of dimeric associates of the Н-type decreases and that of the associates formed due to the donor—acceptor interaction (J- and Т-aggregates) increases. The latter can be stabilized by hydrogen bonds at the periphery of the macromolecule. A series of catalytic activity of the macrocycles under study is inverted compared to the series of stability of the H-dimers.
