测量了新近合成的配合物[M(S-S)(N-N)]在溶剂吡啶、乙醇和氯仿中的电子吸收光谱,比较了二亚胺上不同取代基形成的镍配合物在DMSO和DMF中的电子吸收光谱.并从分子轨道理论角度探讨了这类配合物电子吸收光谱中主要谱带的电子跃迁特性.着重研究了标题配合物分子内配体间荷移跃迁吸收带(LL’CT)与配合物构型、中心离子、配体取代基电子效应和溶剂极性之间的内在本质关系.
The electron absorption spectra of the newly synthesized complexes [M (SS) (NN)] in solvents pyridine, ethanol and chloroform were measured. The electronic structures of the nickel complexes with different substituents on the diimines in DMSO and DMF were compared Absorption spectrum and the electronic transition characteristics of the main bands in the electron absorption spectra of these complexes were discussed from the molecular orbital theory point of view. The study focused on the interaction between the charge-transfer transition (LL’CT) The intrinsic relationship between the configuration of the material, the center ion, the electron effect of the ligand substituent and the polarity of the solvent.
