A copolymer comprising 1,4-diketopyrrolo3,4-cpyrrole (DPP) and thieno3,2-bthiophene 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.
