Turn Off-On Fluorescent CO₂ Gas Detection Based on Amine-Functionalized Imidazole-Based Poly(ionic liquid).

ABSTRACT: Poly(ionic liquids) (PILs) have been widely used for CO₂ capture because their characteristics resemble those of an ionic liquid, yet they have properties typically associated with polymers. We studied the application of the amine-functionalized poly(vinylimidazole)-based PIL (PVIm-NH₂) as a chemosensor. The PVIm-NH₂ was successfully prepared by a facile and low-cost method and was characterized by several analytical techniques: proton nuclear magnetic resonance (¹H NMR), Fourier transform infrared (FT-IR) spectroscopy, gel permeation chromatography (GPC), and spectrofluorometry. The ability of PVIm-NH₂ to detect CO₂ gas was evaluated in the presence of triethylamine (TEA). Under optimized conditions, the detection limit was
