Liquid‐phase sensing of various organic solvents is performed for the first time, using a solvent‐resistant organic‐transistor platform. Sensors composed of a cross‐linked poly(3‐hexylthiophene) (P3HT)–azide co‐polymer and a calixarene derivative exhibit highly sensitive and selective sensing behavior, owing to the selective binding effects of the liquid analytes with the calixarene‐functionalized P3HT–azide, extending the range of their use in practical applications.
