The fluorescent responses of 3, 3′-di (trifluoroacetyl)-1, 1′-bi-2-naphthol toward a variety of amines have been studied. It was found that the aliphatic primary 1, 2-and 1, 5-diamines can greatly enhance the fluorescence of this compound, but under the same conditions, primary, secondary, and tertiary monoamines cannot turn on the fluorescence of this compound. In addition, this compound was shown to be an enantioselective and ...
