| 摘要: 通过紫外-可见光谱滴定法和圆二色光谱法，对手性锌卟啉化合物(ZnP)与4种咪唑类小分子的轴向配位反应的热力学性质进行了研究。测定的热力学数据和圆二色光谱的实验结果显示，配位常数按K(2-MeIm)>K(Im)>K(N-MeIm)>K(2-Et-4-MeIm)的顺序依次减弱，咪唑类配体的轴向配位能力按2-Et-4-MeIm<N-MeIm |

| Abstract: The thermodynamic properties of chiral zinc prophyrin (ZnP) coordinating with imidazole derivatives were studied by means of UV-Vis and circular dichroism spectra. The binding constants decreased in the order of K(2-MeIm)>K(Im)>K(N-MeIm)>K(2-Et-4-MeIm) for imidazole derivatives. The results show that the capability of axial coordination increases in the sequence of 2-Et-4-MeIm<N-MeIm |
