Abstract

Self-association processes of sulfonated cobalt phthalocyanine derivatives were studied. The effects of the size of peripheral substituent and the solvation properties of the solvent on the formation of H- and J-aggregates of metal phthalocyanines were demonstrated. The possibility to control the associative equilibrium of metal phthalocyanines via coordination to DABCO was established. The introduction of DABCO was found to induce dissociation of H- and J-aggregates followed by the formation of sandwich type dimers.
