研究了二氯甲烷溶液中二乙胺(L)与氯合(meso-四-间甲基苯基卟啉)铁(Ⅲ)的轴向配位反应.用光谱法测得不同温度下反应的平衡常数,求得(m-CH_3)TPPFe(Ⅲ)Cl+L=(m-CH_3)TPPFe(Ⅲ)Cl·L反应的标准摩尔焓和摩尔熵.同时,对反应的动力学与反应机理进行了研究.也研究了反应物和产物的紫外可见光谱,并讨论了取代基及轴向配体对铁卟啉紫外可见光谱的影响。
The axial coordination reaction between diethylamine (L) and chloro (meso-tetra-m-methylphenylporphyrin) iron (Ⅲ) in dichloromethane solution was studied.The content of (M-CH_3) TPPFe (Ⅲ) Cl + L = (m-CH_3) TPPFe (Ⅲ) Cl·L reaction was investigated by using the equilibrium constant and the equilibrium constants, and the kinetics and reaction mechanism of the reaction The UV-vis spectra of reactants and products were also studied, and the influence of substituents and axial ligands on UV-Vis spectra of ferroporphyrins was also discussed.
