We synthesized two kinds of poly(1,3-phenyleneethynylenes), one has (+)-menthoxycarbonyl groups at all repeating units and the other has (+)-menthoxycarbonyl groups and n-dodecyloxy groups alternately. Self-supporting membranes could be obtained easily by solvent casting. Enantioselective permeations of the polymers were investigated by pervaporation of 2-butanol. Enantioselective permeabilities of the membrane consisting of one-handed helical foldamer and unfoldamer were clarified.
我们合成了两种聚(1,3-
苯乙炔),一种在所有重复单元上都有(+)-门冬羰基,另一种交替有(+)-门冬羰基和正
十二烷氧基。自支撑膜可通过溶剂浇铸法轻松获得。通过对
2-丁醇的渗透研究了聚合物的对映选择渗透性。澄清了由单手螺旋折叠聚合体和展开聚合体组成的膜的对映体选择渗透性。
