Abstract Efficient gas sensors have been designed using a versatile platform based on organic field-effect transistors incorporating a monomolecular film of receptor compounds at the interface between the semiconductor and dielectric layers. Using a substituted porphyrin as a receptor component allowed us to increase substantially sensitivity of the sensors and induce group selectivity with respect to ammonia and substituted amines. Designed devices demonstrated good operational stability and might be used for food quality control and have also a potential in medical diagnostics in the context of analysis of exhailed air components.

基于具有卟啉单层受体的有机场效应晶体管的胺选择性气体传感器

摘要 使用基于有机场效应晶体管的多功能平台设计了高效的气体传感器，在半导体和介电层之间的界面处结合了受体化合物的单分子膜。使用取代的卟啉作为受体组分使我们能够显着提高传感器的灵敏度并诱导对氨和取代胺的基团选择性。设计的设备表现出良好的操作稳定性，可用于食品质量控制，并且在分析呼出空气成分的背景下也具有医疗诊断的潜力。
