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.

Disclosed is a bis-imide compound comprising two or more aryl moieties substituted with ethynyl moieties and the two or more aryl moieties each having one or more polar substituents. Further disclosed is a polymer composition comprising a copolymer polymerized from a monomer mixture of (a) one or more first monomers comprising a bis-imide compound comprising two or more aryl moieties substituted with ethynyl moieties and the two or more aryl moieties each having one or more polar substituents; and (b) one or more second monomers comprising two or more cyclopentadienone moieties. The polymer compositions exhibit favorable properties for use in electronics and displays applications.

Polyimide-polyarylene polymers

Disclosed is a coating comprising a polymeric layer, wherein the polymeric layer comprises a reaction product of a first monomer comprising two or more aromatic acetylene groups and a second monomer comprising two or more cyclopentadienone groups, or a cured product of the reaction product. The coating may or may not additionally contain a crosslinker and/or a thermal acid generator. Optical thin films made from the coatings exhibit refractive indices that make them useful as interlayers for matching refractive indices between adjacent layers of display devices; thereby improving device output efficiency.
