摘要

(Figure Presented) The binding affinities of a cholic-acid-based fluorescent neutral receptor toward dicarboxylate anions and amino acids have been investigated in a CH₃OH/H₂O system (1:1, 0.01 M HEPES buffer, pH = 7.4) by fluorescence titration experiments. The synthetic host bearing four convergent functionalities strongly binds glutamate via multiple hydrogen bonds with a binding constant of (5.57 ± 0.88) × 10 ⁶.
