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.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.
