| Abstract |
Small molecular cages based on 1,3,5-trisubstituted benzene skeleton were synthesized as anion receptors for the selective recognition of the fluoride anion. The cages are comprised of three imines or amines as hydrogen bond acceptors and three pyrroles as hydrogen bond donors. 1H NMR spectroscopic analysis showed that the cages were able to bind only the fluoride anions in the organic media even in the presence of various test anions such as halides, the hydrogen sulfate, the sulfate, the hydrogen phosphate, the pyrophosphate, the bicarbonate anions. This high selectivity for the fluoride anion is ascribable to the small size and the rigidity of the cavity formed by three imino-pyrrole groups. Further details on the synthesis and binding properties of the receptors will be presented. |
