| Abstract |
A new heterotritopic ion pair receptor was synthesized. The receptor was comprised of two calix[4]pyrrole units as an anion binding motif and the bisazacrown-6 for cation recognition. 1H NMR spectroscopic analysis revealed that the crown ether moiety forms strong intramolecular hydrogen bonds with the calix[4]pyrroles inhibiting the ability of the calix[4]pyrroles to bind anions. On the contrary, when the receptor was exposed to the calcium cation, the cation was bound to the bisazacrown ether destroying the intramolecular hydrogen bonds between the crown ether and calix[4]pyrroles. As a result, the calix[4]pyrrole units recovered their anion binding ability eventually to form ion pair complexes with CaX2. |
