Excellent mercury(II) ion selectivefluoroionophore based on a 3,6,12,15-tetrathia-9-azaheptadecane derivativebearing a nitrobenzoxadiazolyl moiety

Selective and drastic fluorescence enhancement for mercury ion was observed in 1,4-dioxane–water (60/40) using a fluoroionophore bearing a nitrobenzoxadiazolyl group linked to a 3,6,12,15-tetrathia-9-azaheptadecane moiety.
