| 摘 要： | 通过紫外-可见光谱滴定法,对2种羟基锌卟啉配合物与3种咪唑类客体小分子进行轴向配位反应的热力学性质进行了研究.同时,结合荧光光谱法考察了客体浓度对配位反应荧光性质的影响.实验结果表明:(1)咪唑类客体的轴向配位能力按2-MeIm>N-MeIm>Im的顺序依次减弱;(2)咪唑类客体与主体进行轴向配位反应时将产生荧光猝灭效应.

| Abstract: | The thermodynamic properties were studied by means of UV-vis spectra between two kinds of hydroxy Zn porphyrin and imidazoles derivatives.The fluorescence character of axial coordination reaction was investigated from the guest concentration.The results showed:(1) the intensity of axial coordination decreased in sequence of 2-MeIm>N-MeIm>Im;(2) the fluorescence quenching had been exhibited when imidazole derivatives coordinated host. |
