Stibonium ions for the fluorescence turn-on sensing of F- in drinking water at parts per million concentrations.
Additional Document Info
The 9-anthryltriphenylstibonium cation, (+), has been synthesized and used as a sensor for the toxic fluoride anion in water. This stibonium cation complexes fluoride ions to afford the corresponding fluorostiborane 1-F. This reaction, which occurs at fluoride concentrations in the parts per million range, is accompanied by a drastic fluorescence turn-on response. It is also highly selective and can be used in plain tap water or bottled water to test fluoridation levels.
