摘要
This work presents an experimental and theoretical investigation about the influence of the dopant in the electropolymerization of alpha-tetrathiophene. Adherent, insoluble, and black polymeric films were obtained in the presence of LiClO4, while no evidence about the formation of polymer was detected with LiCl and LiBr electrolytes. On the other hand, quantum mechanical calculations based on the density functional theory were performed on 1 : 1 charge-transfer complexes formed by alpha-tetrathiophene and X = ClO4, Cl or Br. The consistency between experimental and theoretical results is discussed. (c) 2005 Elsevier B.V.. All rights reserved.
