摘要： 合成了四萘基四苯并卟啉钴配合物(TNTBPCo).用元素分析、紫外可见光谱、红外光声光谱,核磁共振氢谱、摩尔电导进行了表征。用循环伏安法研究了TNTBPCo的电化学性质。结果表明,钴卟啉配合物中心离子由正三价还原为正二价的半波电位为-0.255V,由正二价还原为正一价的半波电位为-1.175V,卟啉环还原的半波电位为-1.850V,三步电极反应均可逆。

Abstract: The title complex TNTBPCo(Ⅱ) was synthesized and characterized by elemental analysis, UV-vis, spectrum, IR photoacoustic spectrum, H NMR and molar conductance measurements. Its electrochemical behavior has been investigated by cyclic voltammetry in DMSO. The half wave potential of [TNTBPCo(Ⅲ)]+/TNTBPCo(Ⅱ) was -0.255 V and that of TNTBPCo(Ⅱ)/[TNTBPCo(Ⅰ)]-1 was -1.175 V. The half wave potential of redox of porphyrin ring [TNTBPCo(Ⅰ)]-1/[TNTBPCo(Ⅰ)]-2 was -1.850 V.

Key words: tetranaphthyl tetrabenzoporphyrin, colbalt complex, synthesis, characterization, electrochemical behavior
