Abstract

Metal-organic frameworks (MOFs) are crystalline, porous materials synthesized from metallic clusters linked by organic ligands. MOFs can be used in diverse applications such as gas separation and storage, sensing, and catalysis. NU-1000, a Zr-based MOF with tetratopic linkers, is thermally and hydrolytically stable, and contains large mesoporous channels. The typical NU-1000 synthesis combines an initially homogeneous solution of zirconia nodes and benzoic acid in dimethylformamide with a solution of linker (4,4′,4″,4″′-(pyrene-1,3,6,8-tetrayl)tetrabenzoic acid; TBAPy) in dimethylformamide and aging at an elevated temperature. The typical product is composed of large hexagonal rods that are microns in length and contain substantial amounts of a denser phase similar to NU-901. Data will be presented showing that phase pure NU-1000 with particle size in the range of 45 nm to 30 microns can be reproducibly synthesized by controlling experimental conditions. Finally, when very low modulator concentrations were employed, NU-1000 sol-gels formed, which were converted into xerogels by high temperature treatment and aerogels by supercritical CO₂ extraction.
