Abstract This paper designed a simple and quick analysis detection experiment, employing the mechanism of Si-O cleavage via fluorinion in organic synthesis field to research detection of trace F- in solution by fluorescenece dye BODIPY-PhOSi as fluorescence probe.The intensity of fluorescenece has changed when BODIPY-PhO- was preduced by the reaction of BODIPY-PhOSi and fluorinion. Fluorescence probe BODIPY-PhOSi was synthesized by organic synthesis reaction. Trace F- was detected by titration in low concentration probe solution by spectrofluorometer, the fluorescence spectrum was depicted in all kind of concentration of F-. Spectrogram displaed that the response of fluorinion was ratiometric and colorimetric by the fluorescence probe BODIPY-PhOSi. The minimum detection limit was confirmed by calculating spectrogram data. The selectivity of F- in comparison experiments of counter ion showed excellent.
