Two non-interpenetrated zirconium metal-organic frameworks (Zr-MOFs), NPF-200 and NPF-201, were synthesized via the assembly of elongated tetrahedral linkers with Zr6 and Zr8 clusters. They represent the first examples of MOFs to have the β-UH3-like, 4,12,12T1 topology. Upon activation, NPF-200 exhibits the largest BET surface area (5463 m(2) g(-1)) and void volume (81.6%) among all MOFs formed from tetrahedral ligands. Composed of negative-charged boron-centered tetrahedral linkers, NPF-201 is an anionic Zr-MOF which selectively uptakes photoactive Ru(bpy)3 for heterogeneous photo-oxidation of thioanisole.
两个非互穿的锆金属有机骨架（Zr-MOFs），NPF-200 和 NPF-201，通过具有 Zr6 和 Zr8 簇的拉长四面体连接体的组装合成。它们代表了具有 β-UH3 样，4,12,12T1 拓扑结构的 MOFs 的第一个例子。在活化后，NPF-200 表现出所有由四面体配体形成的 MOFs 中最大的 BET 表面积（5463 m(2) g(-1))和空隙体积（81.6%）。NPF-201 由带负电荷的硼中心四面体连接体组成，是一种阴离子 Zr-MOF，可选择性地摄取光活性Ru(bpy)3，用于对甲硫醚的非均相光氧化。
