More Information
Summary:Cobalt, zinc, hydroxoaluminum, and iron complexes of N,N',N",N"'-tetrakis(beta-diethylaminoethyl)phthalocyanine-2,3:9,10:16,17:23,24-tetrakis(dicarboxamide) were synthesized and were converted into the corresponding water-soluble quaternary salts by treatment with methyl iodide, methyl p-toluenesulfonate, diethyl and dimethyl sulfates, and trimethyl phosphate. The electronic absorption spectra of the quaternary salts indicated their considerable aggregation in aqueous solution; the degree of aggregation decreases in going to solutions in ethanol and disappears in DMSO.
