Abstract:
The quenching of the fluorescence of thionine by hydrogen sulphide is reported. The extremely efficient quenching process is attributed to reversible reduction of the thionine dye both in the ground and the excited state leading to the formation of a non-fluorescent semi/leuko thionine. Other toxic gases, namely SO2, HCl, and NH3, were found to have no effect on thionine. Potential analytical applications of this discovery, including development of a fiberoptic H2 sensor, are discussed.
