Abstract：A fluorescent probe (L) with near－infrared (NIR) emission was designed and synthesized , and its structure was characterized.In DMF/H2 O (1/1, v/v, PBS 20 mM, pH＝9.7) solution, probe L exhibits high selectivity to fluoride ion (F －) with high sensitivity and good anti －interference ability over other anions. The recognition mechanism of probe L for F －was confirmed by 1 H NMR comparison experiments , indicating that F－triggered the cleavage of Si －O bond in the probe, releasing the corresponding NIR －emitting fluorophore.In addition, probe L can be used for fluorescence imaging of F －in living MCF－7 cells.
