Abstract
The binding feature of bipyrrole-strapped calix[4]pyrrole 1 for the fluoride anion was examined by a combination of 1H and 19F NMR spectroscopy in DMSO-d6 . Receptor 1 was found to bind the fluoride anion with high affinity via two step-process. Fluoride binding to receptor 1 was proved to facilitate deuterium exchange of the pyrrolic protons in the nominally aprotic deuterated solvent of DMSO-d6.
