Abstract
Detection of volatile acids (VA), such as HCl, TFA, etc., in industrial processes and biological reactions is an actual problem. Pyridinium luminophores is a new class of materials with tunable chemical struc-ture and optical properties. Sensor properties of these materials have not been explored yet. This study presents fabrication of pyridinium luminophores and characterization by XRD, FTIR and photolumines-cence (PL) spectroscopy. The material, tested PL spectroscopy at room temperature, exhibited out-standing sensitivity towards VA, attributed to its chemical structure. These findings underscore the po-tential of pyridinium luminophores for effective detection of VA in hazardous environments.
