[Study on the action force of dimerization of cobalt tetrasulfonate Ph-thalocyanine in aqueous solotion].

The dimerization of cobalt tetrasulfonate phthalocyanine (CoTSPc) was studied in the microemulsion, micelles and aqueous alcoholic solutions. The coordination reaction for the formation of complexes CoTSPc (L), which was formed by cobalt tetrasulfonate phthalocyanine (CoTSPc) plus ligand L(L = NH3, CN-, en), was also studied. The reaction kinetics was discussed and the stability constant K of CoTSPc(L)2 was also calculated from absorbance measurement.
