Abstract: A novel metal organic framework, EMM-39, is described having the structure of UiO-66 and comprising bisphosphonate linking ligands. EMM-39 has acid activity and is useful as a catalyst in olefin isomerization. Also disclosed is a process of making metal organic frameworks, such as EMM-39, by heterogeneous ligand exchange, in which linking ligands having a first bonding functionality in a host metal organic framework are exchanged with linking ligands having a second different bonding functionality in the framework.

Abstract: Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers, typically as a coordination polymer. MOFs may comprise a plurality of metal centers, and a multidentate organic ligand coordinated via at least two binding sites to the plurality of metal centers to define an at least partially crystalline network structure having a plurality of internal pores, and in which the multidentate organic ligand comprises first and second binding sites bridged together with a third binding site comprising a diimine moiety. The multidentate organic ligand may comprise a reaction product of a vicinal dicarbonyl compound and an amine-substituted salicylic acid to define the first, second and third binding sites. Particular MOFs may comprise 5,59′-(((1E,2E)-ethane-1,2-diylidene)bis-(azaneylylidene))bis(2-hydroxybenzoic acid) as a multidentate organic ligand.

Abstract: A process for producing a bimetallic, terephthalate metal organic framework (MOF) having a flexible structure and comprising aluminum and iron cations, comprises contacting a water-soluble aluminum salt, a chelated iron compound and 1,4-benzenedicarboxylic acid or a salt thereof with a fluoride-free mixture of water and a polar organic solvent at a reaction temperature of less than 200° C. to produce a solid reaction product comprising the MOF.

Abstract: 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.
