Many diketopyrrolopyrrole-based (DPP) polymers have shown remarkable transport properties and to fabricate cost efficient materials, the new direct (hetero) arylation polymerization (DHAP) could become a valuable tool. Although the DHAP offers great promise for more efficient, atom-economic and cheaper aromatic C-C bond formations, this method seems to involve a lack of selectivity. Herein, we report an alternating DPP-based copolymer prepared by DHAP that shows a well-defined structure. A rational side-chain design of the comonomers led to a polymer that exhibits a high molecular weight along with excellent charge transport properties (p-type mobility up to 1.17 cm(2) V-1 s(-1)).
