Synthesis and Properties of Sulfophenyl-Substituted Metal Phthalocyanine Complexes

摘要

Sulfonation of 4-phenylphthalic acid gave 4-(p-sulfophenyl)phthalic acid triammoniurn salt which was used in the synthesis of tetra[4-(p-sulfophenyl)]phthalocyanine copper and cobalt complexes by the urea method.The products were characterized by elemental analyses and ~(13)C NMR,IR,and electronic spectra.Some specific features of the electronic spectra of sulfophenyl-substituted metal phthalocyanines were revealed,depending on the central metal atom,solvent nature,and concentration.
