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、N_(1s)及金属M_(2p)_(3/2)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Mn_(2p)_(3/2)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.
XPS was used to study the complexes of tetrakis (p-nitro) phenylporphyrin with Mn, Co, Ni and Cu complexes and six manganese porphyrins with different substituents around the porphyrin. , N_ (1s) and M_ (2p) _ (3/2) binding energies prove that these metal complexes are metalloporphyrin complexes formed by metal inlaid in the conjugated system of large π bond system. The binding energy of Mn_ (2p) _ (3/2) decreases with the decrease of the electronegativity of the porphyrin substituent. The XPS data of different porphyrin can be used to deduce the structure of the substituent in the complex.
