文摘

Novel semiconducting polymers consisting of thiophene and anthracene units without alkyl groups were successfully synthesized through soluble precursor polymers and applied to the organic thin-film transistors (OTFTs). Thermal elimination of leaving groups from the precursor polymers by retro Diels鈥揂lder reaction was proved by thermogravimetric analysis (TGA), FT-IR, and UV鈥搗is spectroscopy. The resulting films of the semiconducting polymers showed good surface morphologies even after thermal elimination, resulting in good semiconducting behavior with mobility of 0.015 cm² V^鈥? s^鈥? in the typical top-contact OTFT. In addition, the devices based on these polymers are stable under ambient conditions and maintained good transistor performance even after being stored in air for 2 months.
