Organic semiconductor films are susceptible to noncovalent interactions, trapping and doping, photoexcitation, and dimensional deformation. While these effects can be detrimental to the performance of conventional circuits, they can be harnessed, especially in field-effect architectures, to detect chemical and physical stimuli. This Review summarizes recent advances in the use of organic electronic materials for the detection of environmental chemicals, pressure, and light. The material features that are responsible for the transduction of the input signals to electronic information are discussed in detail.
有机半导体薄膜易受非共价相互作用、捕获和掺杂、光激发以及尺寸变形的影响。虽然这些效应可能会对传统电路的性能产生不利影响，但它们可以被利用，特别是在场效应结构中，以检测化学和物理刺激。本文综述了近年来利用有机电子材料检测环境化学物质、压力和光的最新进展。详细讨论了负责将输入信号转换为电子信息的材料特性。
