Chiral fluorescence receptors 1 and 2 were synthesized and their structures characterized by IR, 1H NMR, 13C NMR, MS spectra, and elemental analysis. The chiral recognition abilities of 1 and 2 were studied by 1H NMR and fluorescence spectra. The results demonstrate that receptors 1 and 2 with bis(tetrabutylammonium) dibenzoyl tartrate formed a 1:1 complex. Receptor 2 exhibits an excellent enantioselective recognition ability toward the enantiomers of bis(tetrabutylammonium) dibenzoyl tartrate.
