通过锂基聚砜与手性萜烯类化合物桃金娘烯醛的反应，得到了具有手性环境的新型聚合物材料。由此产生的聚合物提供了自立耐用的膜。在膜制备过程中，通过印迹分子的存在，以新型含桃金娘烯醛的聚砜为原料制备了分子印迹膜。D-异构体印迹膜表现出对d-异构体的吸附和扩散选择性，反之亦然。结果是，d-异构体印迹膜优先运输d-异构体，反之亦然。对照非印迹膜对外消旋谷氨酸混合物也表现出渗透选择性。由于吸附和扩散的选择性，分子印迹膜的渗透选择性表现为协同作用。
Novel polymeric materials, having a chiral environment, were obtained by the reaction of lithiated polysulfone with chiral terpenoid myrtenal. The resulting polymers gave self-standing durable membranes. Molecularly imprinted membranes were prepared from the novel myrtenal-containing polysulfones by the presence of print molecules during the membrane preparation process. The d-isomer imprinted membrane showed d-isomer adsorption and diffusivity selectivity, and vice versa. As a result, the d-isomer imprinted membrane transported the d-isomer in preference to the l-isomer, and vice versa. The control non-imprinted membrane also showed permselectivity toward racemic glutamic acid mixtures. The expression of permselectivity for the molecularly imprinted membranes was synergistically due to adsorption and diffusivity selectivity.
