Two chiral fluorescence receptors 3a and 3b based on calix[4]arenes were synthesized, and their chiral recognition properties for enantiomeric malate were studied by fluorescence and 1 H NMR spectra in CHCl 3 . The addition of either l- or d-malate caused obvious fluorescence quenching of the host solution. Different fluorescent responses demonstrate that the two receptors have good...
Two chiral fluorescence receptors 1 and 2 have been synthesized, and their structures characterized by IR, 1 H NMR, MS spectra and elemental analysis. The chiral recognition of the receptors was studied by 1 H NMR and fluorescence spectra. The results demonstrate that the receptors and tetrabutylammonium mandelate formed a 1:1 complex. Two receptors exhibit good chiral recognition...
