A fluorescent sensor is discovered to exhibit high sensitivity at one emission wavelength and high enantioselectivity at another when treated with a chiral diamine. By using this fluorescent sensor, it is demonstrated for the first time that both the concentration and enantiomeric composition of a chiral substrate can be determined simultaneously with one fluorescence measurement.

for chiral diamines. UV absorption and NMR spectroscopic methods have been used to study the interaction of the sensor with amines. These studies have demonstrated that the intramolecular OH···O═C hydrogen bonding of the sensor is important for both the reactivity of its trifluoroacetyl group with the amines and its fluorescent responses. The interaction of both of the two amine groups of a diamine molecule
