摘要
利用改进了的 Mac Diarmid氧化偶联方法合成了苯 /胺封端的苯胺四聚体 .通过对循环伏安曲线的分析 ,给出二聚体经由电化学氧化 -化学偶联成为四聚体的机理 .
Phenyl/amino\|capped tetraaniline was prepared by chemical oxidation coupling and electrochemical cyclic voltammetry methods. The MacDiarmids method of oxidation coupling was improved. The aqueous HCl was replaced with a mixture solution of HCl and acetone and (NH\-4)\-2S\-2O\-8 was used as oxidant instead of FeCl\-3. The reaction displays a higher yield and the product tetraaniline has a higher purity owing to the improvement. In the mixture solution system, tetraaniline can be synthesized by electrochemical cyclic voltammetry method. The mechanism by which tetraaniline was prepared from \{\%p\%\|amino\} diphenylamine was proposed. The product was characterized by MALDI\|TOF MS and FTIR.
