A ratiometric fluorescence halide sensor based on covalently immobilization of quinine and benzothioxanthene
Abstract
A new fluorescence chemical sensor for the determination of Cl−, Br− and I− has been successfully demonstrated. The membrane contains two fluorophores that display two largely different response spectra. The first fluorophore, N-(2-methacryloxyethyl) benzo[k,l]thioxanthene-3,4-dicarboximide (MBTD, benzothioxanthene derivative), used as reference was halide-insensitive. The second fluorophore, quinine sulphate, used as sensitive carrier was …
