采用螺旋选择性聚合法合成了一种带有N-（2-羟乙基）氨甲基配体的手性螺旋聚苯乙炔。在所得的聚合物膜中，配体可以与Cu ~（2+）络合。在外消旋苯丙氨酸水溶液的渗透中，Cu ~（2+）络合膜的对映选择性比原膜提高了3倍左右。
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.
