University of Alicante assisted in meeting the publication costs of thisarticle.The redox process undergone by the electrochemically synthesized poly(2,2-dithiodianiline), poly(DTDA), has been examined inacetonitrile-water mixtures by electrochemical and spectroscopic techniques. The spectroscopic properties of this material are equivalent to those exhibited by the chemically synthesized one. The polymeric structure displays a ladder structure, with S-S bonds serving as interconnections between two adjacent polyaniline chains. The kinetic reversibility of the RS–SR <=> 2RS−reaction is very poor for the DTDA monomer species, and this irreversibility is retained in the polymeric material. According tothe results presented, the hypothesis that poly(DTDA) could display a high energy density due to the simultaneity of theleucoemeraldine <=> emeraldine and dithiolate <=> disulfide electrochemical transformations does not seem justified.Ministerio de Ciencia y Tecnología (MAT2004-1479); Generalitat Valenciana (GV06-106)
