Spectroscopic and kinetic studies of β-cyclodextrin-linked L- and D-phenylalanine cyanoethyl esters in aqueous solution reveal an unusual intramolecular complexation mode where the hydrophobic portion of the amino acid resides outside the host cavity; L- and D-derivatives show different binding geometries and energies.
