A bilayer organic field effect transistor (OFET) sensor utilizing a phenol functionalized molecule as a receptor layer, designed to enhance interaction with a target vapor dimethyl methylphosphonate (DMMP) is presented. The presence of this receptor layer is shown to enhance the sensing properties of the device, supporting the hypothesis that the phenolic receptor material is hydrogen bonding to the DMMP vapor molecules.
