摘要: 用XPS研究了四-(对-硝基)苯基卟啉及其Mn、Co、Ni、Cu配合物和卟啉周边带有不同取代基的6种锰卟啉配合物.π→π跃迁能、N1s及金属M2p3/2结合能的位移证明,这些金属配合物是金属镶嵌在大π键体系共轭环中形成的金属卟啉配合物.不同锰卟啉中Mn2p3/2结合能随卟啉取代基团电负性的降低而下降,不同锰卟啉的XPS数据可用于推断配合物中取代基的结构.

Abstract: The tetra-(p-nitrophenyl) porphyrin and its Mn(Ⅲ), Co(Ⅱ), Ni(Ⅱ) and Cu(Ⅱ) complexes and six manganese porphyrin complexes were investigated by XPS.π→π transition energy and shift of binding energies of N1s and Mn2p3/2 show that these metallic compounds are porphyrin metal complexes formed by the mosaic of metal atom into the π-electron system of the macrocycle structure of the prophyrins.The experimental results show that the binding energies of Mn2p3/2 of different kinds of manganese porphyrin complexes descend as the electronegativity of substituents on porphyrin ring decreases.The XPSdata of different manganese porphyrin complexes may be used to infer the structures of the substituents of the complexes.

Key words: Porpllyrin metal complexes, XPS, Electronegativity
