The selectivity of \u003cb\u003eNBT\u003c/b\u003e has been explored based on combination of desilylation reaction and modulation of the excited-state intramolecular proton transfer (ESIPT) from the desilylation product to F\u003csup\u003e−\u003c/sup\u003e. The method exhibited a high selectivity and a great sensitivity toward fluoride anions through ‘turn-on’ chromogenic activity and sensitivity. The structure of HNBT has been established by single-crystal XRD. Density functional theory and TDDFT calculations were performed in order to demonstrate the electronic properties of HNBT, \u003cb\u003eNBT\u003c/b\u003e and their anion. Upon treatment with fluoride in aqueous CH\u003csub\u003e3\u003c/sub\u003eCN solution, the TBS protective group of probe \u003cb\u003eNBT\u003c/b\u003e was removed readily and ESIPT of the probe was switched on, which resulted in a decrease of the emission band at 415 nm and an increase in a new fluorescence peak around 586 nm. An easy-to-prepare test paper, obtained by dipping the paper into the solution of \u003cb\u003eNBT\u003c/b\u003e, was able to detect fluoride ions in practical samples. The detection limit of the probe in the determination of fluoride ions was 10.18
