[OBJECT] To provide a metal-organic framework having high hygroscopicity under low humidity conditions, and a method for producing such a metal-organic framework. [SOLVING MEANS] A method for producing a coordinatively unsaturated metal-organic framework includes the steps of providing a precursor metal-organic framework comprising a metal cluster and a polycarboxylic acid ion and a monocarboxylic acid ion coordinated to the metal cluster, and allowing the precursor metal-organic framework and a metal salt having a Lewis acidity to coexist in a solvent to desorb at least a part of the monocarboxylic acid ion, which is coordinated to the metal cluster, from the metal cluster, as well as a coordinatively unsaturated metal-organic framework, including an M.sub.6O.sub.8-x(OH).sub.x-type metal cluster and carboxylic acid ions including a polycarboxylic acid ion as a polydentate ligand and a C.sub.1-3 monocarboxylic acid ion as a monodentate ligand coordinated to the metal cluster.

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.

A sparsely pillared organic-inorganic hybrid compound is provided. The sparsely pillared organic-inorganic hybrid compound includes: two inorganic material layers, each extending in one direction and facing each other; and an organic material layer disposed between the two inorganic material layers, wherein each of the inorganic material layers has a gibbsite structure in which a divalent metal cation is doped to an octahedral site, and the organic material layer includes a plurality of pillar portions, each of which is chemically bound to each of the two inorganic material layers such that the two inorganic material layers are connected to each other.

The present invention relates to low temperature process for preparing nanoparticles of porous crystalline Fe-, Al- or Ti-based MOF carboxylate materials with low polydispersity index, and uses thereof, particularly as catalyst support for carrying out heterogeneously catalyzed chemical reactions, or as gas storage/separation/purification material, or as matrix for encapsulating active principles (medicine, cosmetics).

Sorbent compositions that includes a base sorbent material having a high porosity and surface area and a boron-selective agent are particularly useful for the sequestration of boron from waste materials such as coal combustion residual leachate (CCRs). By using a boron-selective agent in conjunction with a high surface area base sorbent material such as activated carbon or biochar, a sorbent composition with a high capacity for sequestering boron at relatively low cost is provided.

A metal organic framework and a method for preparing the same, and an adsorption device employing the metal organic framework are provided. The metal organic framework includes a 3,5-pyridinedicarboxylic acid and a metal ion, which is an aluminum ion, a chromium ion, or a zirconium ion, wherein the 3,5-pyridinedicarboxylic acid is coordinated to the metal ion.

This disclosure is generally directed to polymerization catalysts derived from 1,5-diazabicyclooctanes, catalyst systems utilizing such catalysts, and processes to polymerize alpha olefins therewith.
