Highly Porous Zirconium Metal–Organic Frameworks with β-UH 3 -like Topology Based on Elongated Tetrahedral Linkers
Two non-interpenetrated zirconium metal–organic frameworks (Zr-MOFs), NPF-200 and NPF-201, were synthesized via the assembly of elongated tetrahedral linkers with Zr 6 and Zr 8 clusters. They represent the first examples of MOFs to have the β-UH 3-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] 2+ for heterogeneous photo-oxidation of thioanisole.
