Sensors based on organic field‐effect transistors (OFETs) must overcome challenges in reproducibility, sensitivity, and selectivity. Here we describe an approach to increase the sensitivity and induce selectivity within an existing (OFET) through the incorporation of an evaporated sensor layer based on a calix[n]arene molecule. The mild method does not influence device properties, and is amendable to incorporation into reproducible, commercial transistors.
