Insight into High-Performance Conjugated Polymers for Organic Field-Effect Transistors

Abstract

Summary Compared with traditional silicon electronics, electronic devices based on organic field-effect transistors (OFETs) offer unique advantages, including mechanical flexibility, solution processability, and tunable optoelectronic properties. During the past several years, impressive advances have been made in OFETs, particularly in conjugated polymer-based FETs. Numerous FETs based on high-performance polymers have been developed thanks to the efforts of material design and device optimization. A remarkable mobility of more than 10 cm2 V−1 s−1 has been achieved in OFETs, which provides a promising opportunity for applications in flexible displays and wearable devices. This review describes the recent progress of this field from four aspects: basic knowledge, material design strategies, solution-processable techniques, and functional applications of OFETs. In addition, the current challenges and future outlook of this field are briefly discussed.
