The properties of porphyrins can be changed through the choice of peripheral substituents and inserted metal ions . To obtain porphyrin complexes with novel structures, 5,10,15,20-tetrakis(p-4-fluorobenzoyloxy) phenyl porphyrin(TFBOPPH_ 2 ) and its transition metal complexes {TFBOPPM [M=Mn(Ⅲ), Fe(Ⅲ), Co(Ⅱ), Ni(Ⅱ), Cu(Ⅱ) and Zn(Ⅱ)]} were synthesized and characterized by means of UV-Vis, IR photoacoustic spectrometry, ~ 1 H NMR, elemental analyses, molar conductance, and XPS methods. A structure is proposed, in which one porphyrin molecule is coordinated with a transition metal ion in a tetradentate fashion, while the chlorine ion is the balanceable anion in Fe(Ⅲ) and Mn(Ⅲ) complexes.
