Solution Phase Measurement of Both Weak σ and C−H···X− Hydrogen Bonding Interactions in Synthetic Anion Receptors
摘要:
A series of tripodal receptors preorganize electron-deficient aromatic rings to bind halides in organic solvents using weak a anion-to-arene interactions or C-H center dot center dot center dot X- hydrogen bonds. H-1 NMR spectroscopy proves to be a powerful technique for quantifying binding in solution and determining the interaction motifs, even in cases of weak binding.
