Here, we investigate the interactions between five representative gaseous analytes and two poly(ionic liquids) (PILs) based on sulfopropyl acrylate polyanion in combination with alkylphosphonium cations, P4,4,4,4 P4,4,4,8, their nanocomposites fullerenes (C60, C70) to reveal potential of PILs as sensitive layers for gas sensors. The were chosen molecular size (all them containing carbon atoms) variation functional groups: alcohol (ethanol), nitrile (acetonitrile), aldehyde (acetaldehyde), halogenated alkane (bromoethane), carboxylic acid (acetic acid). six variations PILs─P4,4,4,4SPA (1), P4,4,4,4SPA + C60 (1 C60), C70 C70), P4,4,4,8SPA (2), (2 C70)─were characterized by UV–vis Raman spectroscopy, each analyte studied using electrochemical impedance spectroscopy. Exposure all PIL samples acetaldehyde, bromoethane, ethanol leads a decrease diffusion coefficient, while exposure acetic reveals an increase. Fullerene-doping significantly enhances response analyte. Semiempirical quantum mechanical xTB-GFN2 calculations revealed that hydrogen bonding proton transfer events play important role during detection process.
