Abstract: This article examines nanocomposite organometallic thin films based on copper iodide for their potential use as gas sensor materials. The synthesis of the materials, the thin film production method, and the results of IR spectroscopy and thermogravimetric studies of the compound are described. Using this coordination polymer, resistive thin-film samples were prepared, the resistance dependence on ammonia vapor concentration was measured, and the selectivity for other analytes was assessed.

Keywords: thin-film structures, gas sensors, ammonia sensor, organometallic compounds.
