由1，4-二酮并[3，4-c]吡咯和硫代[3，2-b]噻吩基组成的共聚物PdBT-co-TT在有机薄膜晶体管中表现出高达0.94 cm(2)V-1 S(-1)的高空穴迁移率。由pi-pi堆积和给体-受体相互作用产生的强分子间相互作用导致了具有有序片层结构的互联聚合物网络的形成，这为电荷载流子的传输建立了高效的途径。
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 cm(2) V-1 s(-1) in organic thin-film transistors. The strong intermolecular interactions originated from pi-pi 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.
