标题:Solid-State Synthesis Of Precursors Of Metal-Organic Frameworks
发明人：MAJANO GERARDO J; FALKOWSKI JOSEPH M

摘要:Metal-organic frameworks (MOFs) are highly porous entities comprising a multidentate ligand coordinated to multiple metal atoms, typically as a coordination polymer. MOFs are usually produced from a solvent in powder form under hydrothermal or solvothermal synthesis conditions. Alternately, powder-form precursors of MOFs may be formed by milling or mulling a substantially solid mixture of a metal salt and a multidentate organic ligand, optionally in the presence of a small amount of a solvent. The powder-form precursors may then undergo heating, typically in the absence of applied shear, to produce the corresponding MOF. Mulling may be differentiated from milling at least in that mulling applies to the substantially solid mixture at a non-constant pressure and milling applies a constant pressure while forming the powder-form precursor. In some cases, mulling may promote more effective formation of the powder-form precursor compared to milling.

摘要:The present invention relates to monocrystalline metal organic frameworks comprising chromium ions and carboxylate ligands and the use of the same, for example their use for storing a gas. The invention also relates to methods for preparing metal organic frameworks comprising chromium, titanium or iron ions and carboxylate ligands. The methods of the invention allow such metal organic frameworks to be prepared in monocrystalline or polycrystalline forms.
