Abstract
AbstractThree title compounds have been designed and synthesized in high yields as novel anion receptors, which show a higher selectivity for F− than other halide ions. The binding properties for fluoride ions of the receptors have been examined by UV‐Vis and 1H NMR spectroscopy, indicating that a 1:1 stoichiometry complex is formed between the receptors and fluoride ions through hydrogen bonding interactions in DMSO solution. In addition, because these receptors have more binding points, they have better binding properties for anions than the molecular tweezer receptors based on thiourea we reported last time.
