采用后合成修饰(PSM)技术将水杨醛锚装到UMCM-1-NH2上,得到席夫碱功能化的多孔金属-有机骨架化合物UMCM-1-NH-Sal,在该化合物孔道内的席夫碱N、O原子上螯合铜离子得到UMCM-1-NH-Sal-Cu催化剂,并用核磁共振氢谱(1H NMR)、X射线衍射(PXRD)、热重分析(TG)、N2吸附-脱附等手段对催化剂进行了表征,将其用于催化有机胺和环氧化物的开环反应制备β-氨基醇,结果表明该催化剂具有良好的催化效果.
By the method of post-synthetic modification of MOFs,salicylaldehyde was anchored to UMCM-1-NH2 to give a Schiff base functionalized porous compound UMCM-1-NH-Sal. The copper ion can coordinate with N atoms and O atoms inside the channels of the compound to give another compound UMCM-1-NH-SalCu. The compound could catalyze the ring-opening reaction of epoxides with amines to yield β-amino alcohols,and showed good catalytic performance in such reactions.
