Synthesis and Chiral Recognition Properties of Novel Fluorescent Chemosensors for Amino Acid

The charge neutral chiral optical sensors 1a ∼ d containing thiourea and amide groups were synthesized by simple steps in good yields and their structures were characterized by IR, 1 H NMR, 13 C NMR, MS spectra and elemental analysis. The enantioselective recognition for α-phenylglycine and phenylgl...

Description
Summary:The charge neutral chiral optical sensors 1a ∼ d containing thiourea and amide groups were synthesized by simple steps in good yields and their structures were characterized by IR, 1 H NMR, 13 C NMR, MS spectra and elemental analysis. The enantioselective recognition for α-phenylglycine and phenylglycinol was examined by fluorescence emission and UV-vis spectra. The fluorescence and UV-vis spectra changes of 1a were obvious when the enantiomers of α-phenylglycine anion were added, which exhibited that 1a has good enantioselective recognition ability towards α-phenylglycine.
