Neutral classes of amide-based macrocycle have been synthesized and the anionbinding abilities are assessed by UV-vis titration and 1H nmr experiments. Results indicate that higher anionbinding abilities are observed for H2PO4−, F− and AcO−, but almost no affinity for Cl−, Br−, I− and OH−. The 1H nmr spectra shows that the interactions between the receptors and fluoride anion depend on two factors
