Description
Summary:The synthesis and polymerization of fused‐ring 1,7‐didodecyl‐1,7‐dihydrothieno[3,2‐b:4,5‐b′]dipyrrole monomer are reported. The FeCl3‐mediated oxidative polymerization and Stille coupling polymerization of the thienodipyrrole monomer were employed to generate homopolymers and an alternating copolymer with thiophene. The synthesized polymers have molecular weights ranging from 1600 to 6500 g mol−1 and display the absorption maxima at ≈355 nm. The synthesis of 1,7‐didodecyl‐1,7‐dihydrothieno[3,2‐b:4,5‐b′]dipyrrole monomer and its polymerization are reported for the first time. The FeCl3‐mediated oxidative polymerization and Stille coupling polymerization of the thienodipyrrole monomer are employed to generate homopolymers and an alternating copolymer with thiophene.
