Synthesis, characterization and photosensitivity of tetrakis--(2-methyl-8-quinolinoxy) metallophthalocyanines

Abstract

Four amphipathic cobalt(II), nickel(II), copper(II), and zinc(II) coordination compounds of tetrakis-?-(2-methyl-8-quinolinoxy)phthalocyanine are synthesized using “DBU catalytic method”. The titled complexes are characterized by elemental analysis, mass spectra, UV-Vis, and IR spectra. In addition, the rates of photogenerated singlet oxygen and the rate constants of photodynamic oxidation of amino-acid substrate by the complexes are measured under the optical excitation at 670 nm, and the relations between their structures and their photosensitivities are discussed.
