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C_(D)CMP-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) m^(2)/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 C_(D)CMP-1 was 4%, the permeability of(D,L)-phenylalanine was 7.75×10^(-9) m^(2)/h, and the excess of enantiomer was 60.6% ee, showing high enantiomer separation performance.
