摘要
通过酸碱混合配体策略合成了 2例含刚性双三氮唑配体的金属有机骨架(MOF)材料:｛[Zn2(L)(TP)2(H2O)·H2O]}n(1)和[Zn(L)(HTMA)]n(2),其中 L=4,4'-(3,3'-dimethyl-(1,1'-biphenyl)-4,4'-diyl)bis(4H-1,2,4-triazole),H2TP=对苯二甲酸,H3TMA=1,3,5-均苯三甲酸.用单晶X射线衍射表征其结构.结构分析表明,MOF1显示出3,6-双节点的二维结构,其拓扑符号为(42·6)2(48·66·8),MOF2呈现为经典的sql二维拓扑结构.在温和条件下,2对CO2与环氧化物的环加成反应具有优异的催化活性,且重复使用至少3次后仍然保持其催化性能.
Abstract
Two metal-organic frameworks(MOFs)containing rigid bis(triazole)ligand,namely {[Zn2(L)(TP)2(H2O)·H2O]}n(1)and[Zn(L)(HTMA)]n(2),where L=4,4'-(3,3'-dimethyl-(1,1'-biphenyl)-4,4'-diyl)bis(4H-1,2,4-triazole),H2TP=terephthalic acid,H3TMA=1,3,5-benzenetricarboxylic acid,were synthesized by using acid-base mixed ligands strategy and structurally characterized by X-ray single-crystal diffraction.Structural analysis reveals that MOF 1 displays a 3,6-connected 2D structure with a new topological point symbol of(42·6)2(48·66·8),while MOF 2 presents a 2D sql topology structure.The catalytic studies reveal that 2 exhibits excellent catalytic activity for the cycloaddition reaction of CO2 with epoxides under mild conditions.Furthermore,2 can be reused at least three times while maintaining its catalytic ability.CCDC:2296181,1;2296182,2.
