Ditopic ion pair receptors, bearing bezocrown moiety as cation binding site and calix[4]pyrrole as anion-binding sites, have been synthesized and fully characterized. Binding studies confirmed that the synthesized receptors form stable complex with various anions in organic media. The cation binding site, on the other hand, showed selectivity for cesium ion. When the fluoride-bound host was treated with alkaline metal ions, distinctive ion-pair formation with cesium ion was observed. When the fluoride-bound host was treated with Li+ or Na+ ion, decomplexation of the bound fluoride was observed. On the contrary, the fluoride complex of simple oligoether-strapped calix[4]pyrrole was treated with Cs+, the cation bound to the cup of the calix[4]pyrrole to form receptor-shared ion-pair complex. The chloride-bound host displayed different complexation behavior. Namely, the Li+ ion bound to the crown moiety to form the contact ion-pair complex. The supramolecular binding properties of the anion-bound hosts will be presented in detail.
