제목 Highly Sensitive and Selective OFET-Based Liquid-Phase Sensors Based on Cross-linked Polymer Semiconductors
초록 An organic field-effect transistor (OFET)-based sensors have been demonstrated for sensing various types of analytes including chemicals, biological species, light, and pressure. In general, however, conjugated polymers suffer from poor chemical resistance toward liquid-phase organic solvents, which limits their practical applications to commercial electronic devices. Herein, we demonstrate solvent-resistant OFET-based sensors using cross-linkable organic semiconductor. Calixarene derivatives have been adopted to increase the sensitivity and selectivity of the OFET-based sensors. Various liquid-phase organic solvents have been tested successfully, and reliable sensing responses have been obtained. Our findings demonstrate a novel methodology for the fabrication of high-performance organic sensors and extend the practical applications of OFET-based sensors.
