  • Hafnium-based metal-organic frameworks as epoxide ring-opening catalysts
    Patent number: 10479758
    Abstract: Metal-organic frameworks (MOFs) having inorganic nodes that comprise an octahedral Hf6 cluster capped by eight ?3-ligands and having twelve octahedral edges, wherein the ?3-ligands are hydroxo ligands, oxo ligands or aquo ligands; and organic linkers connecting the organic nodes, the organic linkers comprising 1,3,6,8-tetrakis(p-benzoic acid)pyrene units; wherein eight of the twelve octahedral edges of the inorganic nodes are connected to the 1,3,6,8-tetrakis(p-benzoic acid)pyrene units are provided.
    Type: Grant
    Filed: January 24, 2019
    Date of Patent: November 19, 2019
    Assignee: NORTHWESTERN UNIVERSITY
    Inventors: Omar K. Farha, Joseph T. Hupp, M. Hassan Beyzavi, Casey J. Stephenson, Yangyang Liu

  • Zirconium- and hafnium-based metal-organic frameworks as epoxide ring-opening catalysts
    Patent number: 10233145
    Abstract: Metal-organic frameworks (MOFs) and method of using the MOFs to catalyze reactions involving epoxide ring-opening mechanisms are provided. The structure of the MOFs can be represented by the formula: M6(?3-ligand)8(OHx)8(TBAPy)2, where M is Zr or Hf, the ligands are selected from hydroxo-, oxo- and aquo-ligands, and x is independently selected from 1 or 2.
