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.
