| Abstract: | Calix4]arene-based receptors linked to amide and pyridine moieties have been synthesised in four steps from calix4]arene, and characterised by 1H and 13C NMR spectroscopy. The recognition properties of these receptors towards different anions were evaluated using 1H NMR and computational studies. The receptors show modest selectivities towards dihydrogen phosphate versus carboxylates. |
