摘要：

采用“自下而上”策略，成功合成了2种含薄荷酯的手性共轭微孔聚合物（CCMP）。以CCMP为分散相，醋酸纤维素（CA）、乙基纤维素（EC）为基质，采用相转换法，制备了3种混合基质膜。扫描电子显微镜显示，CCMP在基质中分散均匀。在氨基酸外消旋体的对映体分离时，当分散相CDCMP-1质量分数为4％，混合基质膜对(D,L)-苯丙氨酸的透过率为7.75×10-9 m2/h，对映体过量为60.6％ee，表现出较高的对映体分离性能。

In this paper, two kinds of chiral conjugated microporous polymers (CCMP) containing menthol esters were successfully synthesized by the "bottom-up" strategy. Using CCMP as dispersed-phase, cellulose acetate (CA) and ethyl cellulose (EC) as substrates, three mixed-matrix membranes were prepared by phase conversion method.Scanning electron microscopy showed that CCMP was evenly dispersed in the matrix.When the mass fraction of CDCMP-1 was 4%, the permeability of (D,L) -phenylalanine was 7.75×10-9 m2/h, and the excess of enantiomer was 60.6% ee, showing high enantiomer separation performance.
