Abstract
Poly(dithienopyrrole-dithienothiophene) copolymers can be obtained as good conducting electrode films by electrolytic oxidation of acetonitr ile solutions of monomer mixtures (electrolyte: tetrabutylammonium per chlorate). They show good electrochromic characteristics. Films of pol y(dithienopyrrole-thionaphtheneindole) and poly(dithienothiophene-thio naphtheneindole) copolymers can be obtained in the same way as the pre vious ones. They are adherent to the electrodes but are insulating and non-electrochromic; the reason for this behaviour is proposed to be t he break of conjugation in the polymeric chain due to the thionaphthen eindole moiety.
