  • Modified metal-organic framework (MOF) compositions, process of making and process of use thereof
    Patent number: 11958033
    Abstract: This invention relates to modified MOF materials, methods of preparing them and processes using them. A modified MOF of the invention is modified by impregnating a MOF with an inorganic metal salt. The starting MOF contains at least one linker or ligand which contains an aryl amino group as part of its structure. These modified MOFs are able to adsorb either basic or acidic toxic industrial compounds (TIC). The modified MOFs can be used to remove TICs from various gaseous streams such as air.

  • Metal organic frameworks for removal of elemental impurities in pharmaceutical products
    Patent number: 11642650
    Abstract: This invention relates to a method of using MOF adsorbents to remove elemental impurities from feed streams comprising active pharmaceutical ingredients (API). The process involves contacting the feed stream comprising API and elemental impurities with the MOF at purification conditions to obtain a purified stream with provides an API which has a concentration of the elemental impurity below its permitted daily exposure. The process can be carried in a batch mode where the MOF and feed stream are admixed in a vessel for a given amount of time or continuously by flowing the feed stream through a column or adsorbent bed containing the MOF adsorbent.

  • AN INORGANIC APPROACH TO RENDERING METAL-ORGANIC FRAMEWORKS ELECTRICALLY CONDUCTIVE
    Publication number: 20210269461
    Abstract: Electrically conductive, metal-organic framework (MOF) materials, methods of making the materials, and chemical sensors incorporating the materials are provided. The electrically conductive MOF materials are formed from mesoporous MOF crystals having continuous strands of electrically conductive inorganic oxides within their porous structures. The inorganic strands are formed by the condensed-phase grafting of molecular metal species onto MOF nodes.
