| 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，MOF 1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)，MOF 2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. | |
