Donor–Acceptor‐Conjugated Polymer for High‐Performance Organic Field‐Effect Transistors: A Progress Report

Abstract

Polymeric semiconductors have demonstrated great potential in the mass production of low-cost, lightweight, flexible, and stretchable electronic devices, making them very attractive for commercial applications. Over the past three decades, remarkable progress has been made in donor-acceptor (D-A) polymer-based field-effect transistors, with their charge-carrier mobility exceeding 10 cm 2 V −1 s −1 . Numerous molecular designs of D-A polymers have emerged and evolved along with progress in understanding the charge transport physics behind their high mobility. In this review, the current understanding of charge transport in polymeric semiconductors is covered along with significant features observed in high-mobility D-A polymers, with a particular focus on polymeric microstructures. Subsequently, emerging molecular designs with further prospective improvements in charge-carrier mobility are described. Moreover, the current issues and outlook for future generations of polymeric semiconductors are discussed.

Tuning Interfacial Properties by Spontaneously Generated Organic Interlayers in Top‐Contact‐Structured Organic Transistors

“…Organic field‐effect transistors (OFETs) have the advantages of low‐cost, large‐area, or mass‐production processing, and are used for a variety of potential applications. [ 1–4 ] Therefore, many efforts have been made to improve their electrical performance over the past decades. Impressively, some recent studies have shown that the field‐effect mobility ( µ FET ) has been increased to more than 10 cm 2 V −1 s −1 by synthesizing structurally optimized organic semiconducting materials or by applying appropriate processing techniques (chemical doping, aligned crystal structure, etc.)…”

Synthesis and Properties of Thiophene and Aniline Copolymer Using Atmospheric Pressure Plasma Jets Copolymerization Technique

“…In recent, donor–acceptor (D–A) conjugated copolymers (CCPs) have been widely investigated on the band gap engineering in the industrial and academic areas for flexible organic field-effect transistors, photocatalysts, polymer solar cells, and electrochromic applications [ 1 , 2 , 3 , 4 ]. Among of D–A CCPs, the copolymer of aniline with thiophene is known to increase the conductivity of polyaniline (PANI) and thiophene-based polymeric materials have great electrochromic properties suitable for displays such as high contrast, fast switching times, and stabilities [ 5 , 6 , 7 ].…”

Versatile nature of anthanthrone based polymers as active multifunctional semiconductors for various organic electronic devices

“…10 Therefore, extensive efforts have continuously been made to improve the device performance, particularly for OFETs and solar cells (OPVs & PSCs). [11][12][13][14] Among all these efforts, it is apparent that development of organic semiconductors (OSCs), which provide the core functionality of the devices, have played a significant role in advancing this field.…”
