Abstract
Chemical gas sensors have important applications in the fields of environmental supervision, chemical pharmaceuticals, disease diagnosis and so on. With the rapid development of organic materials and device fabrication methods, research in organic thin film transistor (OTFT) based gas sensors has made significant progress and excellent sensing performances have been achieved. This review highlights recent progress in OTFT based gas sensors in the past several years, including the advances in typical sensing materials, interfacial engineering, and microstructure regulation. Furthermore, other developments in gas sensors such as application of new materials and integration of sensor arrays are also discussed in detail. This review aims at providing a comprehensive and fundamental understanding of OTFT based gas sensors, in terms of selection of sensing materials, functional thin film formation, the influence of interfacial properties and gas sensing mechanisms. And it is hoped that this will contribute to the fabrication of high-performance gas sensors and the development of related industries.
