A new 2,3,4,5-tetrafluorophenyl substituted tripodal amide-based receptor L1 and its pentafluorophenyl substituted analogue L2 were explored for halide binding studies in their solution and solid states. Comparative solution state binding studies of halides with L1 and L2 were carried out by 1H-NMR titration in CDCl3. Detailed solution state 1H-NMR studies show that halides bind with L1 and L2 with

Extraction of KF/KCl from aqueous solution by distinct cationic and anionic receptors is demonstrated. Structural studies of the extracted complexes showed 1D-polymers of the receptors containing respective ions in their cavities.
