  • A calix[4]pyrrole (1) bearing a quaternary ammonium pendant via its meso phenoxy linker has been synthesized as the bromide salt form. It was revealed by 1H NMR spectroscopic analyses performed in DMSO-d6 that receptor 1 binds F- with high affinity and selectivity over other halide anions. The binding of receptor 1•Br- with F- and Cltakes place by anion metathesis with the anions including F- and Cl-.
