A new functionalization technique, solvent-assisted ligand incorporation (SALI), was developed to efficiently incorporate carboxylate-based functionalities in the Zr-based metal-organic framework, NU-1000. Unlike previous metal node functionalization strategies, which utilize dative bonding to coordinatively unsaturated metal sites, SALI introduces functional groups as charge compensating and strongly bound moieties to the Zr6 node. Utilizing SALI, we have efficiently attached perfluoroalkane carboxylates of various chain lengths (C1-C9) on the Zr6 nodes of NU-1000. These fluoroalkane-functionalized mesoporous MOFs, termed herein SALI-n, were studied experimentally and theoretically as potential CO2 capture materials.
一种新的功能化技术,溶剂辅助配体引入(SALI),被开发用于在基于 Zr 的金属有机骨架 NU-1000 中高效地引入基于羧酸盐的官能团。与以前利用配位不饱和金属位点的金属节点功能化策略不同,SALI 将官能团作为电荷补偿和强结合基团引入到 Zr6 节点。利用 SALI,我们已经有效地将各种链长(C1-C9)的全氟烷羧酸酯接枝到 NU-1000 的 Zr6 节点上。这些氟烷官能化介孔 MOF ,在此称为 SALI-n,被作为潜在的 CO2 捕获材料进行了实验和理论研究。
