采用水热法成功制备了由Zn-ε-Keggin单元和有机连接体组成的三维聚钼酸盐基金属有机骨架材料{[PMo8VMo4VIO37(OH)3Zn4][BPE]2}·[BPE](1)。化合物 1 由 Zn-ε-Keggin 单元和 BPE 配体组成，具有令人着迷的 dia 拓扑结构的 5 重互穿框架。研究了化合物1的催化性能，实验表明，1作为路易斯酸多相催化剂可以有效促进CO2与环氧化物的环加成反应。此外，化合物1也被研究作为LIBs负极材料，其在第100次循环时显示出546 mAh g-1的可逆容量。
A three-dimensional polymolybdate-based metal-organic framework (POMOF) consisting of Zn-ε-Keggin unit and organic linker, {[PMo8VMo4VIO37(OH)3Zn4][BPE]2}·[BPE] (1), was successfully obtained by the hydrothermal method. Compound 1 is composed of Zn-ε-Keggin units and BPE ligands, featuring a fascinating 5-fold interpenetrating framework with dia topology. The catalytic performance of compound 1 was investigated, and experiments showed that 1 could effectively facilitate the cycloaddition reaction of CO2 with epoxides as Lewis acid heterogeneous catalyst. Moreover, compound 1 also was studied as LIBs anode material, and it showed reversible capacity of 546 mA h g-1 at 100th cycle.
