Four amphipathic cobalt(Ⅱ),nickel(Ⅱ),copper (Ⅱ),and zinc(Ⅱ) coordination compounds of tetrakis,α,(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.
