用电子光谱法研究了一种由六个碳原子的脂肪二酰胺链连接两个四苯基卟啉的双核钴 (Ⅱ )配合物 (Co2 PP4 )在DMF溶液中与双氧的可逆结合作用 ,测定了反应的Hill系数n =1.84,ΔG0 ( 2 98K) =- 12 .3kJ·mol-1,P1/2 =6.8kPa ,热力学数据表明Co2 PP4 分子内两个金属卟啉环之间存在着强的协同作用 .由双卟啉双钴 (Ⅱ )配合物与双氧作用形成的配合物经ESR证实为超氧金属配合物 ,结合方式属于Co -O-2 超氧类型 Electron spectroscopy was used to study the reversible binding of dinuclear cobalt (Ⅱ) complex (Co2 PP4) with two carbon atoms linked by aliphatic diamides to two tetraphenylporphyrins in DMF solution. The Hill coefficients n = 1.84, ΔG0 (2 98K) = - 12.3 kJ · mol-1, and P1 / 2 = 6.8 kPa were determined. The thermodynamic data showed that there existed strong interchain between the two metalloporphyrin rings in Co2 PP4 The complex formed by the bis-porphyrin bis-cobalt (II) complex with dioxygen was confirmed to be a superoxide metal complex by ESR and the binding mode belongs to Co-O-2 superoxide type
