Abstract Two chiral fluorescence receptors ( 1 , 2 ) were synthesized, and their structures were characterized by IR, 1 H NMR, 13 C NMR, mass spectra and elemental analysis. The chiral recognition of receptors was studied by 1 H NMR and fluorescence spectra. The results demonstrate that receptors and dibenzoyl tartrate anion formed a 1:1 complex. The receptor 1 exhibited a good enantioselective recognition ability toward the enantiomers of dibenzoyl tartrate anion.
