A fluorescent anion receptor (3) based on amide macrocycle was synthesized and the recognition ability for F, Cl, Br, I, H2PO4 and AcO was investigated by fluorescence, UV-vis and 1H NMR spectra. The results indicate that receptor 3 has a good selective recognition property for F and formed a 1∶2 complex. The association con-stant of complex between 3 and F was calculated from the changes in fluorescence intensity.

Key words: azacrown, anion receptor, fluorescence, anion recognition
