摘要: 用XPS研究了四苯基(2-硝基)卟啉及其过渡金属化合物。由π→π*跃迁能、跃迁几率及N1S和金属M2p3/2结合能的位移证明,这些化合物是金属镶嵌在大π体系共轭环中而成的金属配合物。其中,-NO2是连在卟啉环上。引入-NO2后,金属结合能升高,Lewis酸性增强,因而与轴向配位体的加合能力增强。

Abstract: The metal Complexes coordinated with tetrapbenyl porphyrin and tetraphenyl-2-nitroporphyrin were investigated by XPS. These metal complexes in which ions were mosaiced into big π system of conjugated ring structrue were demonstrated by π→π* transition energy, transition probability and N1tshift of binding energy. Furthermore, it was proved that -NO3group is in conjunction with a pyrrole ring and this leads to an increase of Lewis acidity.
