A series of bis(pyridine)cobalt corroles with one or three nitrophenyl groups on the meso positions of the corrole macrocycle were synthesized and characterized as to their electrochemical and spectroscopic properties in dichloromethane, benzonitrile, and pyridine. The potentials for each electrode reaction were measured by cyclic voltammetry and the electron-transfer mechanisms evaluated by analysis of the electrochemical data combined with UV–visible spectra of the neutral, electroreduced, and electroxidized forms of the corroles. The proposed electronic configurations of the initial compounds and the prevailing redox reactions involving the electroactive central cobalt ion, the electroactive conjugated macrocycle, and the electroactive meso-nitrophenyl groups are all discussed in terms of solvent binding and the number of the nitrophenyl groups and other substituents on the meso-nitrophenyl rings of the compounds.

非水介质中双（吡啶）钴（硝基苯基）环的电化学

合成了一系列在大分子环的内消旋位置上带有一个或三个硝基苯基的双（吡啶）钴，并对其在二氯甲烷，苄腈和吡啶中的电化学和光谱性质进行了表征。通过循环伏安法测量每个电极反应的电势，并通过分析电化学数据以及中性，电还原和电氧化形式的环氧乙烷的紫外-可见光谱，评估电子转移机理。拟议的初始化合物的电子构型以及涉及电活性中心钴离子，电活性共轭大环化合物和电活性内消旋体的普遍氧化还原反应关于-硝基苯基，均以溶剂结合以及化合物的内消旋-硝基苯基环上的硝基苯基和其他取代基的数目为基础进行讨论。
