초록

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. <
