Enantioselective permeability through membranes from a poly(substituted phenylacetylene) having a chiral helical backbone and achiral bidentate ligands as pendant groups
A chiral helical poly(phenylacetylene) bearing N-(2-hydoroxyethyl)aminomethyl groups as ligand sites was synthesized by helix-sense-selective polymerization. In the obtained polymeric membrane, the ligands could complex with Cu2+. In permeation of aqueous solution of racemic phenylalanine, enantioselectivity in permeation through the Cu2+ complexing membrane was about 3 times higher than that of the original membrane.
