摘要：

In this paper, a convenient oxidants free acid polymerization method is developed to synthesize poly(3,4-ethylenedioxythiophene) (PEDOT). p-Toluenesulfonic acid (p-TsOH) is served as catalyst to direct polymerization of EDOT. The electron spin resonance spectra revealed that EDOT was protonated into radical species under p-TsOH. As-obtained PEDOT has a highest average degree of polymerization of 11.3 and the structure details are characterized by H-1 NMR, GPC and FTIR. An acid promoted EDOT protonation polymerization mechanism is proposed and clarified. (C) 2018 Elsevier B.V. All rights reserved.
