Dithienocoronenediimide-Based Copolymers as Novel Ambipolar Semiconductors for Organic Thin-Film Transistors

摘要

Solution processible 7r-conjugated polymers are of extensive scientific and technological interest as semiconducting materials in organic electronics. Compared to small molecules, tuned rheo-logical properties of polymeric solutions enable proper ink formulations for high-throughput printing processes on large-area, light-weight, and flexible substrates. Since the demonstration of the first polymeric semiconductor based on a electrochemically grown polythiophene, a number of semiconducting polymers with a wide range of optoelectronic properties have emerged, which has been crucial for developing high-performance organic thin-film transistors (OTFTs), light-emitting transistors (OLETs), and photovoltaic cells (OPVs), as well as to better understanding charge transport mechanisms.
