Abstract

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.

    In addition to the original electropolymerization of monomeric DTPs to generate homopolymeric materials, the electropolymerization of mixed solutions of DTP and other building blocks were reported as early as 1994, resulting in the production of random copolymer 41 (Fig. 24) [70]. A following report expanded the study to also include the random copolymer 42 [71]. For copolymer 41, films containing less than 70% DTP were neither conducting nor electrochromic and it was concluded that the DTP segments were largely responsible for the polymer properties.

    The electron donor and acceptor capability to participate in electron conjugation serves electron or hole injection and transport property to the heteroatom. In addition to this, use of copolymer may serve as a source of conductivity [12], film forming ability [13,14], processability [15–19], stability and better morphology [20]. There are many examples in literature investigating the match of different acceptor and donor units referring to the effects to improve aforementioned properties.
