Abstract

A molecular organization of N-dansyl-L-leucine-appended and N-dansyl-D-leucine-appended beta-cyclodextrins (CDs) was analyzed by nuclear magnetic resonance spectroscopy. NMR analysis of the CDs indicated the presence of a dansyl moiety in N-dansyl-D-leucine-appended beta-CD that was located in cavity with a deeper inclusion depth compared to the moiety of N-dansyl-L-leucine-appended. The presence of a deeper dansyl moiety in the beta-CD was caused by differences in enantiomeric configuration.

Abstract

The synthesis and characterization of fluorophore-amino acid-cyclodextrin (CD) triads as molecular sensors were carried out. The fluorescent CDs, which displayed variable fluorescence and absorption intensities upon addition of a guest molecule, were N-dansyl-L-leucine-modified and N-dansyl-D-leucine-modified beta-CD, and N-dansyl-L-leucine-modified and N-dansyl-D-leucine-modified gamma-CD.
