摘要： 合成了硫代烃基四氮杂卟啉2,3,7,8,12,13-六(甲硫基)-17,18-一(二噻英)四氮杂卟啉[H2Pz(dtn)(mt)6]及其过渡金属配合物MPz(dtn)(mt)6,由元素分析、质谱、1HNMR、UV-Vis和IR光谱对其组成和结构进行了表征,通过循环伏安测试结果讨论了H2Pz(dtn)(mt)6的电化学性质,证明H2Pz(dtn)(mt)6的还原过程为单电子连续传输过程,属于CE机理.研究了H2Pz(dtn)(mt)6对正极材料MnO2在锂离子电池中的修饰作用.结果表明,H2Pz(dtn)(mt)6对改善锂离子电池的初始充放电容量和循环次数都有明显的增加.

Abstract: A lower symmetrical alkylthioporphyrazine, 2,3,7,8,12,13-hexakis(methylthio)-17,18-mono(dithiin)porphyrazine, [H2Pz(dtn)(mt)6] , and their derivatives MPz(dtn)(mt)6 [M=Cu, Zn, Co] were prepared and characterized by the methods of elemental analysis, mass spectra, 1H NMR, IR and UV-Vis spectra. The electrochemical behavior of H2Pz(dtn)(mt)6 was studied in DMF solution with the method of CV. The results show that the electron transfer is quasi-one-electron chemical-electronic transfer process. The modification on the cathode materials MnO2 in lithium ion battery was studied. The results shows that the initial charging and discharging capacity as well as the cyclic number are all increased.

Key words: Porphyrazine, Metallic complex, Electronic spectra, Electrochemical property, Lithium ion battery
