  • Patent number: 10807875
    Abstract: The zeolite UTD-1 may be formed under hydrothermal synthesis conditions using a directing agent that does not include a metal atom therein. Methods for synthesizing the zeolite UTD-1 may comprise: combining at least a silicon atom source and a directing agent having a structure of in an aqueous medium; forming the zeolite in the aqueous medium under hydrothermal synthesis conditions, such that the zeolite has a framework silicate with a cationic portion of the directing agent occluded within pores or channels of the framework silicate; and isolating the zeolite from the aqueous medium.

  • Publication number: 20200101439
    Abstract: Methods of synthesizing crystalline metal-organic frameworks (MOFs) comprising polytopic organic linkers and cations, where each linker is connected to two or more cations, are provided. In the disclosed methods, the linkers are reacted with a compound of formula MnXm, where M is cationic Be, Mg, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Zr, Nb, Mo, Ru, Rh, Pd, Cd, or Hf, X is anionic, n and m are integers. The reacting is buffered by a buffer devoid of metal coordinating functionality when the pKa of the anion is below a threshold related to the lowest pKa of the linker. The reacting is optionally not buffered when the pKa of the anion is at or above this threshold. The disclosed methods lead to product phase MOF in which crystal growth is controlled leading to control over molecular diffusion.

  • Patent number: 10518257
    Abstract: A novel metal organic framework, EMM-33, is described having the structure of UiO-67 and comprising bisphosphonate linking ligands. EMM-33 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-33, 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.

  • Publication number: 20190126237
    Abstract: Polyamines with lengths carefully tailored to the framework dimensions are appended to metal-organic frameworks such as Mg2(dobpdc) (dobpdc4-=4,4?-dioxidobiphenyl-3,3?-dicarboxylate) with the desired loading of one polyamine per two metal sites. The polyamine-appended materials show step-shaped adsorption and desorption profiles due to a cooperative CO2 adsorption/desorption mechanism. Several disclosed polyamine-appended materials exhibit strong ability to capture CO2 from various compositions. Increased stability of amines in the framework has been achieved using high molecular weight polyamine molecules that coordinate multiple metal sites in the framework. The preparation of these adsorbents as well as their characterization are provided.

  • Patent number: 10118169
    Abstract: Metal-organic framework (MOFs) compositions based on chiral phosphine-, chiral oxazoline-, chiral pyridine-, and chiral diene-derived organic bridging ligands were synthesized and then post-synthetically metalated with metal precursors such as Ru and Rh complexes. The metal complexes could also be directly incorporated into the MOFs. The MOFs provide a versatile family of recyclable and reusable single-site solid catalysts for catalyzing a variety of asymmetric organic transformations, including the addition of arylboronic acids to ?,?-unsaturated ketones and alkimines, the hydrogenation of substituted alkene and carbonyl compounds, and cyclization reactions. The solid catalysts can also be integrated into a flow reactor or a supercritical fluid reactor.
