Enantioselective Permeability through Membranes from a Poly(substituted phenylacetylene) Having a Chiral Helical Backbone and Achiral Bidentate Ligands as Pendant Groups

摘要

A chiral helical poly(phenylacetylene) bearing N-(2-hydor-oxyethyl)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.
