“…[30,102] The applicability of OFETs for chemical sensing has been revealed by the uniform and reproducible switching profiles for reliable analyte detection, and robustness in both the DC bias stress and the cycle tests. [125] Meanwhile, the employment of printing fabrication methods such as ink-jet [43,126] and gravure printing [127] instead of drop-casting methods in device manufacturing processes could further improve the transistor characteristics for chemical sensing. [125] In addition, the necessity of a reference electrode in the extended-gate-type OFETs could be a bottleneck in on-site analysis.…”

An organic field‐effect transistor (OFET) is the representative amplification device showing a switching profile by applying a gate voltage, which indicates the potential as a chemical sensor device in combination with appropriate molecular recognition materials. On the other hand, the realization of OFET‐based chemical sensors for real‐sample analysis has been limited owing to the instability of organic semiconductive materials under ambient conditions and the difficulty of the designs of molecular recognition materials. Herein, this Review describes methodologies and actual approaches to maximize the potential of the OFETs as chemical sensor platforms based on fusion technologies between organic electronics and molecular recognition chemistry.This article is protected by copyright.
