Spectroscopic and electrochemical study of the redox process of poly(2,2'-dithiodianiline)
Cotarelo Méndez, María de los Ángeles - Huerta Arráez, Francisco - Quijada Tomás, César - Pérez Martínez, José María - Valle de la Cortina, María Angélica del - Vázquez Picó, José Luis

Formato:	info:eu-repo/semantics/article
Enlaces:	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…
