摘要：

Poly(dithienopyrrole-dithienothiophene) copolymers can be obtained as good conducting electrode films by electrolytic oxidation of acetonitrile solutions of monomer mixtures (electrolyte: tetrabutylammonium perchlorate). They show good electrochromic characteristics. Films of poly(dithienopyrrole-thionaphtheneindole) and poly(dithienothiophene-thionaphtheneindole) copolymers can be obtained in the same way as the previous ones. They are adherent to the electrodes but are insulating and non-electrochromic; the reason for this behaviour is proposed to be the break of conjugation in the polymeric chain due to the thionaphtheneindole moiety.
