摘要:A novel metal-organic framework (MOF) templated process for the synthesis of highly porous inorganic sorbents for removing radionuclides, actinides, and heavy metals is disclosed. The highly porous nature of the MOFs leads to highly porous inorganic sorbents (such as oxides, phosphates, sulfides, etc) with accessible surface binding sites that are suitable for removing radionuclides from high level nuclear wastes, extracting uranium from acid mine drainage and seawater, and sequestering heavy metals from waste streams. In some cases, MOFs can be directly used for removing these metal ions as MOFs are converted to highly porous inorganic sorbents in situ.

标 题 :MOF synthesis method
发明人：NI ZHENG; MASEL RICHARD I
权利人:UNIV ILLINOIS
摘要:A rapid, simple and versatile metal organic framework molecule (MOF) synthesis method particularly adapted to make non-linear MOFs includes heating MOF precursors, such as a metal or metal oxide and an organic ligand, in a microwave oven for a period sufficient to achieve crystallization. Microwave-assisted MOF synthesis yields high quality MOF crystals in a reaction time ranging from about 5 seconds to about 2.5 minutes, compared to hours and days required in conventional solvothermal and hydrothermal methods. In addition, microwave assisted methods provide MOF materials with uniform crystal size and well-defined shape. Further, microwave synthesis of MOFs allows the size and shape of MOF crystals to be tailored for use in a wide range applications by manipulating reaction conditions. Secondary growth processes may also be employed to grow larger crystals using seeds obtained from microwave-assisted synthesis methods.

标题 :Methods of making porous molecular structures

权利人:GEORGIA TECH RES INST
摘要:Disclosed herein is a method of making a porous molecular structure from a solution comprising an insoluble metal containing material and a ligand-providing material. In some embodiments, the porous molecular structure can be a Metal-Organic Framework (MOF). Ionic metal salts are the most common type of metal source for MOF production, but dissolution of metal salts complicates solvent recycling and creates corrosion and oxidation issues through evolved nitrate and chloride anions. Elucidating information that leads toward more efficient production of these versatile nanomaterials, while extending the knowledge base of how MOFs form during reaction, is critical to advancing MOF materials into large-scale use. Disclosed herein are improved methods for controlled synthesis of porous molecular structures such as MOFs comprising a solution-based synthesis with insoluble metallic precursor.

标题:Solid-State Synthesis Of Precursors Of Metal-Organic Frameworks
发明人：MAJANO GERARDO J; FALKOWSKI JOSEPH M
权利人:EXXONMOBIL RES & ENG CO
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.

标题:Synthesis of macrocyclic tetraamido-N ligands
发明人：GORDON-WYLIE SCOTT W; COLLINS TERRENCE J

摘要:New synthetic methods for the preparation of macrocyclic amido-N donor ligands are provided. The primary method of the present invention involves in general only two synthetic steps. In the first step, an α or β amino carboxylic acid is allowed to react with an optimal (approximately stoichiometric) amount of an activated malonate or oxalate derivative with mild heating. Upon completion of the double coupling reaction, hydrolysis of the reaction mixture yields a diamide containing intermediate (a macro linker). In the second step, stoichiometric amounts of a diamine, preferably an orthophenylene diamine, are added to the macro linker intermediate in the presence of a coupling agent and heat. This second double coupling reaction, is allowed to proceed for a period of time sufficient to produce a macrocyclic tetraamido compound. The substituent groups on the α or β amino carboxylic acid, the malonate, and the aryl diamine may all be selectively varied so that the resulting tetraamido macrocycle can be tailored to specific desired end uses. The macrocyclic tetraamide ligand may then be complexed with a metal, such as a transition metal, and preferably the middle and later transition metals, to form a robust chelate complex suitable for catalyzing oxidation reactions.
