A novel phthalocyanine,2,9(10),16(17),23(24)-tetra(4-benzoyl)phenoxyphthalocyanine,and its complexes with Zn(II),Cu(II),Co(II),and Ni(II) have been synthesized and characterized by a combination of elemental analysis,IR,1 H NMR,UV-vis spectroscopy and mass spectrometry.All of the materials are very soluble in common organic solvents such as dichloromethane,chloroform,tetrahydrofuran,N,N-dimethylformamide and dimethyl sulfoxide.The Q band wavelengths of the complexes decrease in the order:Zn > Cu > Ni > Co.Redox processes were observed at 1.06,0.74,0.51 and 0.98 V for the free phthalocyanine,at 0.72 and 1.04 V for the Co(II) complex,at 1.24,0.77,0.24,0.61 and 0.91 V for the Cu(II) complex,and at 0.74 and 1.20 V for the Ni(II) complex.The cyclic voltammograms of the phthalocyanine ring of the four species are similar,with reduction and oxidation couples each involving a one-electron transfer process.
