我们研究了２，９，１６，２３－四羧基酞菁钴（Ⅱ）与硫醇（２－巯基乙醇）、硫酚（苯硫酚）轴向配位反应的热力学性质，发现了配位过程中中心离子钴由二价变为一价的现象。用紫外－可见分光光度法和Ｍｉｌｌｅｒ－Ｄｏｒｏｕｇｈ 数据处理方法，确定了体系的配位数和平衡常数；利用温度系数法求得了体系的ΔｒＨｍ ， ΔｒＳｍ 。探讨了温度对反应的影响 We studied the thermodynamic properties of the axial coordination of cobalt (II) 2,9,16,23-tetracarboxyphthalocyanine with thiol (2-mercaptoethanol) and thiophenol (thiophenol) In the center of the ion cobalt from two into a monovalent phenomenon. The coordination number and equilibrium constant of the system were determined by UV-Vis spectrophotometry and Miller-Dorough data processing. The ΔrHm and ΔrSm of the system were calculated by the temperature coefficient method. The effect of temperature on the reaction was discussed
