Porous Zirconium Metal-Organic Framework Constructed from 2D → 3D Interpenetration Based on a 3,6-Connected kgd Net

摘要

A new porous zirconium metal-organic framework (Z r MOF), Zr_6 (μ_3 - O) _4 (μ_3 - OH)_4(OH)_6(H_2O)_6(BTB)_2?6DMF?H_2O (1; H_3BTB = 5′-(4-carboxyphenyl)[1,1′:3′,1″-terphenyl]-4,4″-dicarboxylic acid), based on Zr6 clusters and tricarboxylate ligands has been constructed and characterized. The Zr_6 clusters were linked by BTB ligands to generate a 2D network of kgd topology. The interpenetrations among the 2D networks gave rise to a 3D porous framework, which represents the first Zr MOF constructed from 2D → 3D interpenetration. The gas uptake and catalytic properties for 1 have also been studied.
