大环配体过渡金属配合物——Ⅴ.四苯基卟啉衍生物及其金属配合物的电子吸收光谱

TRANSITION METAL COORDINATION COMPOUNDS OF MACROCYCLIC LIGAND V.The Electronic Absorptive Spectra of Tetraphenylporphyrine Deravatives and Their Metal Coordination Compounds

测定了四个四苯基卟啉衍生物及其六个金属配合物的电子吸收光谱,用群论和HMO 法计算了四苯基卟啉共轭体系的π分子轨道能级和相应的对称性。基于八分子轨道模和对组态相互作用的估计,讨论单电子π-π~*跃迁。由此对四苯基卟啉衍生物及其金属配合物的电子吸收光谱各谱带给予指认。

In the paper electronic absorption spectra of four tetraphenylporphyrine deravatives and their six metal coordination compounds have measured.The π molecular orbital energy levels and symmetry of tetraphenylporphyrine conju- gate system was calculated by means of both Group Theory and HMO method. The π—π transitions of one electron was discussed by Eight Molecular Orbi- tal model and estimation for configuration interaction.Rest on these the bands of electronic absorptive spectra for tetraphenylporphyrine deravatives and their metal coordination compounds have identified respectively.
