A High Mobility P‐Type DPP‐Thieno[3,2‐
Abstract:A copolymer comprising 1,4‐diketopyrrolo[3,4‐c]pyrrole (DPP) and thieno[3,2‐b]thiophene moieties, PDBT‐co‐TT, shows high hole mobility of up to 0.94 cm2 V−1 s−1 in organic thin‐film transistors. The strong intermolecular interactions originated from π‐π stacking and donor‐acceptor interaction lead to the formation of interconnected polymer networks having an ordered lamellar structure, which have established highly efficient pathways for charge carrier transport.
