<p>Naphthyl crown ether ligand molecules containing at least two naphthyl groups that are covalently bonded to suitable solid supports and coated by hydrophobic organic solvents are disclosed. These compositions and associated methods are characterized by selectivity of desired amine or amino acid enantiomers over their counter-enantiomers and derivatives. The composition preferably has an α-value greater than or equal to 4. This allows for the separation of such enantiomers with nonchromatographic resin bed separations of three separation stages or less.</p> |
