Abstract

See full text

Gas sensors are provided. The gas sensors comprise: a substrate; a plurality of electrodes on the substrate; and a polymeric sensing layer on the substrate for adsorbing a gas-phase analyte. The adsorption of the analyte is effective to change a property of the gas sensor that results in a change in an output signal from the gas sensor. The polymeric sensing layer comprises a polymer chosen from substituted or unsubstituted polyarylenes comprising the reaction product of monomers comprising a first monomer comprising an aromatic acetylene group and a second monomer comprising two or more cyclopentadienone groups, or a cured product of the reaction product. The gas sensors and methods of using such sensors find particular applicability in the sensing of gas-phase organic analytes.
