A new fluorescent probe 6-(2,4-dinitrophenoxy)-2-naphthonitrile (probe 1) was designed and synthesized for the selective detection of hydrogen sulfide (H2S). The addition of H2S to a solution of probe 1 resulted in a marked fluorescence turn-on alongside a visual color change from colorless to light yellow. Importantly, this distinct color response indicated that probe 1 could be used as a visual sensor for H2S. Moreover, probe 1 was successfully used as a signal tool to determine the H2S levels in beer and red wine.
