A fluorescence probe based on naphthalimide-functionalized triarylboron for fluoride ion detection

Fluoride ions (F - ) play a significant role in life science and clinical medicine science. A fluorescence probe ( TN-F ) for detecting fluoride ions was synthesized using naphthalimide as the fluorophore and triarylboron as the recognition group. The selectivity and sensitivity to fluoride ions were determined by UV–visible absorption and fluorescence spectroscopy, which can meet the need for rapid detection (90 s) of F - in organic solution. Moreover, this probe exhibited high anti-interference capability and sensitivity with a detection limit of 0.63 μM, achieving efficient and rapid detection of fluoride ions.
