Abstract: Phenyl/amino-capped tetraaniline was prepared by chemical oxidation coupling and electrochemical cyclic voltammetry methods. The MacDiarmids method of oxidation coupling was improved. The aqueous HCl was replaced with a mixture solution of HCl and acetone and (NH4)2S2O8 was used as oxidant instead of FeCl3. 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 dipheny-lamine was proposed. The product was characterized by MALDI-TOF MSand FTIR.

Key words: Phenyl/amino-capped tetraaniline, Chemical oxidation coupling, Electrochemical cyclic voltammtry method
