A pair of chiral fluorescent sensors for enantioselective recognition of mandelate in water
摘要:
A pair of chiral compounds S-1 and R-1 derived from (1S, 2S) or (1R, 2R)-1, 2-diphenylethane-1, 2-diamine were designed and synthesized, the interactions of S-1 and R-1 with mandelate were studied in H2O (0.01 M HEPES buffer, pH = 7.4) by fluorescence titration experiments. The sensors S-1 and R-1 were found to present enantioselective fluorescent sensing ability to mandelate. The results indicated that the sensors S-1 and R-1 were very promising to be used as fluorescent sensors in determining the enantiomeric composition of mandelate in H2O. (C) 2013 Elsevier B.V.
