Chiral binaphthyl receptors bearing imidazolium or urea groups for the recognition of anions

Two new binaphthyl derivatives 1 and 2 bearing two imidazolium, or bisurea groups were investigated as fluorescent chemosensors for the chiral anion recognition. Receptors 1 and 2 displayed a better selectivity for ( S )-2-phenylbutylate over ( R )-2-phenylbutylate. Isothermal titration calorimeter...

Description
Summary:Two new binaphthyl derivatives 1 and 2 bearing two imidazolium, or bisurea groups were investigated as fluorescent chemosensors for the chiral anion recognition. Receptors 1 and 2 displayed a better selectivity for ( S )-2-phenylbutylate over ( R )-2-phenylbutylate. Isothermal titration calorimeter methods, fluorescence as well as theoretical calculations are utilized to explain chiral selectivity. Graphical Abstract
