该文采用溶剂热法合成了一种共价有机框架材料(COFs)TpBD-(NO,2,),2,,将TpBD-(NO,2,),2,还原为TpBD-(NH,2,),2,后用,D,-(-)-,α,-苯甘氨酸对其进行手性修饰得到手性COFs材料TpBD-(NH,2,),2,-,D,-(-)-,α,-苯甘氨酸。对TpBD-(NO,2,),2,、TpBD-(NH,2,),2,及TpBD-(NH,2,),2,-,D,-(-)-,α,-苯甘氨酸3种COFs材料进行表征,并采用“网包法”制备了TpBD-(NH,2,),2,-,D,-(-)-,α,-苯甘氨酸手性固定相。为考察该固定相的分离性能,将其用于制备高效液相色谱(HPLC)手性柱,并使用正己烷-异丙醇(体积比9∶1)和甲醇-水(体积比9∶1)为流动相,实现了13种手性化合物和5种苯系位置异构体的分离。且该色谱柱具有较好的重现性。实验表明TpBD-(NH,2,),2,-,D,-(-)-,α,-苯甘氨酸用作HPLC固定相用于手性物质和苯系位置异构体分离具有良好的研究意义。
In this work,a covalent organic framework(COF) material TpBD-(NO,2,),2, was firstly synthesized by solvothermal method,which was then reduced to TpBD-(NH,2,),2,,and finally,a chiral COF material TpBD-(NH,2,),2,-,D,-(-)-,α,-phenylglycine was obtained by chirally modifying the TpBD-(NH,2,),2, with ,D,-(-)-,α,-phenylglycine.Three COF materials,i.e.TpBD-(NO,2,),2,,TpBD-(NH,2,),2, and TpBD-(NH,2,),2,-,D,-(-)-,α,-phenylglycine were characterized,and a chiral stationary phase of TpBD-(NH,2,),2,-,D,-(-)-α-phenylglycine was prepared by “net-wrap method”.In order to investigate the separation performance of the stationary phase,it was used to prepare a chiral column for high performance liquid chromatography(HPLC),,n,-hexane-isopropanol(9∶1,by volume) and methanol-water(9∶1,by volume) were used as mobile phases.13 chiral compounds and 5 benzene positional isomers were separated on this column with good reproducibility.The experiment showed that the separation effect of TpBD-(NH,2,),2,-,D,-(-)-,α,-phenylglycine chromatographic column was excellent. It was of a certain research significance to use the chiral COF material TpBD-(NH,2,),2,-,D,-(-)-,α,-phenylglycine as HPLC stationary phase for the separation of chiral substances and benzene isomers.
