Chiral Mono Boronic Acid As Fluorescent Enantioselective Sensor for Mono α-Hydroxyl Carboxylic Acids

New mono boronic acid was found to be an enantioselective fluorescent chemosensor for mono α-hydroxyl carboxylic acids, such as mandelic acid and lactic acid. The chiral sensor shows lower background fluorescence, higher fluorescence enhancement, and enantioselective recognition kinetics toward mandelic acids and lactic acids.
