Furan semiconductors and their application in organic field-effect transistors

A furan ring is frequently integrated into n-conjugated molecules either by fusion with a carbon n- system or as a n-spacer, which significantly alters the photophysical, electrochemical, and charge transport properties of n-conjugated molecules. As an emerging class of organic semiconductors, furan semiconductors have attracted widespread interest owing to their intriguing properties, such as high solubility, photoluminescent quantum efficiency, and carrier mobility. Impressively, both p-and n-type furan semiconductors exhibit great potential for applications in organic field-effect transistors (OFETs), the highest mobility of 7.7 cm2/Vs for a quinoidal oligofuran has been achieved. In this review, we summarize the development of furan semiconductors and their applications in OFETs and provide a perspective on these materials. (c) 2022 Elsevier Ltd. All rights reserved.
