| Abstract |
New ion pair receptors having deep cavities were prepared based on calix[4]pyrroles doubly strapped with crown ethers having various ring sizes. It was revealed by 1H NMR spectroscopic analysis that the receptors were able to bind CsF highly selectively over other akali metal halide salts. In this case, the cesium cation was bound to the crown ether moieties with the fluoride anion being hydrogen bonded to the calix[4]pyrrole NHs. 1H NMR spectroscopic analysis also provided an evidence that the calix[4]pyrrole biscrowns form complexes with a specific cation such as the sodium in the absence of anions bound to calix[4]pyrroles. |
