5, 10, 15, 20-Tetrakis (p-4-fluorobenzoyloxy) phenyl Porphyrin and Its Transition Metal Complexes

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(TFBOPPH2) 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, 1H 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.
