We have designed and synthesized a new fluorescent probe, 2-(3-(2-((tert-butyldiphenylsilyl)oxy)phenyl)-5-(4-methoxyphenyl)-4,5-dihydro-1H-pyrazol-1-yl)benzo[d]thiazole (probe 1), to detect fluoride ion with high selectivity and sensitivity in aqueous media. Upon mixing with NaF, desilylation reaction of probe 1 can be induced to the fluorescence quenching with the detection limit of F⁻ 0.74 μM. Moreover, the probe can be used to detect fluoride ion on real life samples.
