The compounds were characterized by UV, IR, luminescence spectra and 1 H NMR. The energy levels of the π-molecular orbital for the conjugated sys-tem were calculated by the methods of both HMO and Group Theory. The calculated spectral bands of π-π transition were consistent with the observedspectra. The results indicate that three free base porphyrins have D 2h sym-metry and main ligands of five coordination compounds be long to group C 4v .The electron spectra of coordination compounds originated from the conjugated system of macrocyclic ligand. 四苯基卟啉衍生物 过渡金属配合物 HMO法 tetraphenylporphyrine derivative transition metal coordination compound Hückcl Molecular Orbital method 中国科学院科学基金 1988-03-01 2021-04-01 3
