摘要：
A new 7-nitrobenz-2-oxa-1,3-diazole (NBD)-based fluorescent chiral chemosensor (NBD-1) was prepared and applied to the recognition of the two enantiomers of the tetrabutylammonium salts of N-t-Boc-a-amino acids and chiral carboxylic acids including naproxen. In particular, the chiral recognition by the new fluorescent chiral chemosensor for the two enantiomers of N-t-Boc-threonine (tetrabutylammonium salt) was quite excellent, the Stern-Volmer constant ratio (KD/KL) for the two enantiomers being as high as 4.89.
