제목 A Thienoisoindigo-Naphthalene Polymer with Ultrahigh Mobility That Substantially Exceeds Benchmark Values for Amorphous Silicon Semiconductors
초록 Polymer-based electronic devices will soon enter our daily lives as indispensable elements in a myriad of flexible and low-cost flat panel displays. Despite more than a decade of research focused on designing and synthesizing state-of-the-art polymer semiconductors for improving charge transport characteristics, the current mobility values are still not sufficient for many practical applications. The confident mobility in excess of ~10 cm2/Vs is the most important requirement for enabling the realization of the aforementioned near-future products. We report on an easily attainable donor–acceptor polymer semiconductor: poly(thienoisoindigo-alt-naphthalene) (PTIIG-Np). An unprecedented mobility, of 14.4 cm2/Vs, by using PTIIG-Np with a high-k gate dielectric P(VDF-TrFE) is achieved from a coating processing, which is of a magnitude that is very difficult to obtain with TFTs by means of molecular engineering. Therefore, represents a major step towards truly viable plastic electronics.
