Abstract: First synthesis of an alkynylated dithieno[3,2-b:2′,3′-d]pyrrole (DTP) monomer was developed, which allows electrochemical polymerization on platinum and indium tin oxide (ITO) electrodes. The obtained DTP-based polymer (pDTP) was successfully post-modified with redox active and biological… read more here.

Abstract: Two kinds of donor–acceptor π-conjugated copolymer based on poly{[N-hexyl-dithieno(3,2-b:2′,3′-d)pyrrole-2,6-diyl]alt-[isoindigo]} (PDTP-IID) and poly{[N-hexyl-dithieno(3,2-b:2′,3′-d)pyrrole-2,6-diyl]alt-[thiazol-2,5-diyl]} (PDTP-Thz) were investigated. These copolymers were synthesized via a Stille coupling reaction. The results showed the structure–property relationships of different donor–acceptor (D–A) combinations.… read more here.

DOI: 10.1039/d2ra03265a
Abstract: A new N-alkynylated dithieno[3,2-b:2′,3′-d]pyrrole (DTP) monomer was synthesized using a Buchwald–Hartwig amination of 3,3′-dibromo-2,2′-bithiophene with pent-4-yn-1-amine. The obtained monomer was investigated for the possibility of a pre-polymerization modification via Huisgen 1,3-dipolar cycloaddition (“click”) reaction with… read more here.
