Development of DPP-based semiconducting polymers organic field-effect transistors |
| 초록 |
Organic field-effect transistors (OFETs) based on semiconducting polymers have received much attention owing to several key merits such as solution process-ability and mechanical flexibility of semiconducting polymers. In addition, electrical performances of semiconducting polymers now exceed those of thermally evaporated organic semiconductors such as pentacene. For example, recently developed diketopyrrolopyrrole (DPP)-based donor–acceptor (D–A) polymers exhibited high field-effect mobility of ＞10 cm2 V−1 s−1. In this regard, DPP-based semiconducting polymers are considered as benchmark organic semiconductors ready for commercialization in switching elements in the future display. Recent report of side chain engineering in DPP-based polymers indicates that intermolecular stacking can be finely tuned by changing alkyl side chains. Especially, long-branched side chains are beneficial for optimizing π–π stacking and accelerating the intermolecular charge transport. |
