摘要：
A hemicyanine dye with imidazole as the acceptor was designed and prepared as a chemosensor for fluoride anions. The experimental results demonstrated that it is a fluorometric probe for fluoride anion with good sensitivity and high selectivity. This probe showed obvious changes in UV–Vis absorption and fluorescence spectra in the presence of fluoride anions, which are attributed to the deprotonation of N–H on the imidazole moiety with fluoride anions.
