Abstract:
A colorimetric and turn-on fluorescent probe for fluoride ions, tert-butyldimethylsilane 6-acetyl-2-naphtholate, was readily synthesized from 6-acetyl-2-naphthol and tert-butyldimethylchlorosilane (TBSCl). The probe exhibits high sensitivity and good selectivity for fluoride ions in acetonitrile. The inherent mechanism involves the cleavage of the Si-O bond in the probe, which induced yellow color formation and prominent fluorescence enhancement.
