Thiazole‐Based Organic Semiconductors for Organic Electronics

Over the past two decades, organic semiconductors have been the subject of intensive academic and commercial interests. Thiazole is a common electron‐accepting heterocycle due to electron‐withdrawing nitrogen of imine (C=N), several moieties based on thiazole have been widely introduced into organic semiconductors, and yielded high performance in organic electronic devices. This article reviews recent developments in the area of thiazole‐based organic semiconductors, particularly thiazole, bithiazole, thiazolothiazole and benzobisthiazole‐based small molecules and polymers, for applications in organic field‐effect transistors, solar cells and light‐emitting diodes. The remaining problems and challenges, and the key research direction in near future are discussed.
