Abstract:

The anion binding properties of 2,2-dihydroxyl-1,1-binaphtalene (BINOL) derivatives were studied by 1H NMR spectroscopy. BINOL derivatives formed the complex with anions through hydrogen bonding using hydroxyl groups and showed a binding preference to dihydrogen phosphate (H2PO4 -) and acetate (CH3CO2-) in comparison with other anions (Cl-, Br-, I-, NO3-, and HSO4-) tested.
