| Abstract |
Calix[4]arene-calix[4]pyrrole hybrids connected via triazole units were synthesized and their binding properties for cations and anions as well as ion pairs were investigated in solution and in the solid state. It was revealed by 1H NMR spectroscopic analyses that the ion pair receptors were able to bind specific ion pairs such as LiCl and CsCl with high affinity and selectivity over other alkaline metal chloride salts. It was also proved that the receptors formed complexes with LiCl and CsCl in two different binding modes. For instance, in the case of LiCl, the Li+ cation was bound to the calix[4]arene moiety with the aid of the triazole groups with the Cl- anion being bound to the calix[4]pyrrole unit. By contrast, the Cs+ cation was bound to the bowl-shaped calix[4]pyrrole cavity formed as a result of the chloride binding to the calix[4]pyrrole unit. |
