摘　　要：文章以L-苯丙氨酸甲酯和萘-1,5-二磺酰氯为起始原料,合成一种C 2对称性的手性桥联配体L-H 2;继而与锌离子通过溶剂热技术制备一种荧光性的多孔手性配合物1,其晶体结构通过单晶X-射线衍射(X-ray diffraction,XRD)、傅里叶变换红外光谱仪(Fouier transform infrared spectrometer,FTIR)和荧光光谱等技术进行表征。手性吸附实验证明,手性配合物1能够有效地拆分外消旋的氧化苯乙烯,获得对映体过量值为66%的氧化苯乙烯;荧光传感实验结果表明,手性配合物1能够有效区分氧化苯乙烯的2种异构体,其荧光更容易被R构型的氧化苯乙烯对映异构体所淬灭,被淬灭程度达到60%。In this study,a chiral bridging ligand L-H 2 with C 2 symmetry was firstly synthesized using L-phenylalanine methyl ester and naphthalene-1,5-disulfonyl chloride as the starting reactants.A luminescent chiral porous complex 1 was then prepared through the solvothermal reaction with the obtained chiral ligand and zinc ions.Its crystal structure was characterized by single-crystal X-ray diffraction(XRD),Fourier transform infrared spectrometer(FTIR),and fluorescence spectroscopy.Enantiosorption experiment revealed that chiral complex 1 can effectively resolve racemic styrene oxide,yielding chiral styrene oxide with a value of 66%.Fluorescence sensing experiment proved that chiral complex 1 can effectively distinguish the two enantiomers of styrene oxide,which is evident by the fact that its fluorescence was quenched by 60%with R-configuration enantiomer of styrene oxide.
