Abstract
AbstractBased on the reaction between the azido group and hydrogen sulfide (H2S), BTN, an off‐on fluorescent sensor was synthesized, which exhibited a 20‐fold fluorescence enhancement upon addition of H2S, and a 5.6 × 10−8 mol/L detection limit can be reached in 10 min. To check its applicability, an easy prepared test paper strip of BTN was made for rapid and selective detection of hydrogen sulfide in red‐wine samples, the detection limit is as low as 1 µmol/L.
