pH-Controlled recognition of amino acids by urea derivatives of β-cyclodextrin

Water soluble amphiphilic urea-substituted β-cyclodextrins were synthesized and applied as amino acid receptors. A great affinity towards nonpolar amino acids was observed, ranging from 2300 M −1 for alanine to 54 800 M −1 for tryptophan in a highly competitive environment (pH 8 phosphate-buffered w...
