Abstract

Fluorescence quenching of benzopurpurin (BP) by HCl in methanol is investigated. The observed extremely efficient quenching is attributed to the formation of a nonfluorescent exciplex between BP and HCl. Other pollutant gases, such as H2S and NH3, were found not to effect the fluorescence of BP. Possibilities of using this finding to develop a fiber optic HCl sensor are discussed.
