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, 1H 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.
一种新型的酞菁,2,9(10),16(17),23(24)-四(4-苯甲酰)酚氧酞菁及其与Zn(II)、Cu(II)、Co(II)和Ni(II)的配合物已经合成并通过元素分析、红外光谱(IR)、1H NMR、紫外-可见光谱和质谱进行了表征。所有材料在常见有机溶剂中(如二氯甲烷、氯仿、四氢呋喃、N,N-二甲基甲酰胺和二甲基亚砜)具有很好的溶解度。配合物的Q带波长按以下顺序减小:Zn > Cu > Ni > Co。观察到游离酞菁在−1.06 V、−0.74 V、0.51 V和0.98 V处的氧还原过程,Co(II)配合物在−0.72 V和1.04 V处,Cu(II)配合物在−1.24 V、−0.77 V、−0.24 V、0.61 V和0.91 V处,Ni(II)配合物在−0.74 V和1.20 V处。四个物种的酞菁环的循环伏安图相似,均涉及一个电子转移过程的还原和氧化偶。
