20210053042 · 2021-02-25 ·

Lewis acidic metal-organic framework (MOF) materials comprising triflate-coordinated metal nodes are described. The materials can be used as heterogenous catalysts in a wide range of organic group transformations, including Diels-Alder reactions, epoxide-ring opening reactions, Friedel-Crafts acylation reactions and alkene hydroalkoxylation reactions. The MOFs can also be prepared with metallated organic bridging ligands to provide heterogenous catalysts for tandem reactions and/or prepared as composites with support particles for use in columns of continuous flow reactor systems. Methods of preparing and using the MOF materials and their composites are also described.

WATER STABLE COPPER PADDLEWHEEL METAL ORGANIC FRAMEWORK (MOF) COMPOSITIONS AND PROCESSES USING THE MOFS

This invention relates to a Cu-BTC MOF which is water stable. The Cu-BTC MOF has been modified by substituting some of the BTC ligand (1,3,5, benzene tricarboxylic acid) with 5-aminoisophthalic acid (AIA). The resultant MOF retains at least 40% of its as synthesized surface area after exposure to liquid water at 60 C. for 6 hours. This is an unexpected result versus the MOF containing only the BTC ligand. This MOF can be used to abate contaminants such as ammonia in gas streams and especially air streams.

20210046447 · 2021-02-18 · ·

This invention relates to a Cu-BTC MOF which is water stable. The Cu-BTC MOF has open coordination sites and has been post synthesis modified by partially occupying the open sites with a ligand such as acetonitrile (CH.sub.3CN). The resultant MOF retains at least 40% of its as synthesized surface area after exposure to liquid water at 60 C. for 6 hours. This is an unexpected result versus the MOF which has not been post treated with ligands such as acetonitrile. This MOF can be used to abate contaminants such as ammonia in gas streams and especially air streams.

Adamantane-intercalated layered double hydroxide

Embodiments are directed to adamantane-intercalated layered double-hydroxide (LDH) particles and the methods of producing adamantane-intercalated LDH particles. The adamantane-intercalated LDH particles have a general formula defined by [M.sub.1-xAl.sub.x(OH).sub.2](A).sub.x.mH.sub.2O, where x is from 0.14 to 0.33, m is from 0.33 to 0.50, M is chosen from Mg, Ca, Co, Ni, Cu, or Zn, and A is adamantane carboxylate. The adamantane-intercalated LDH particles further have an aspect ratio greater than 100. The aspect ratio is defined by the width of an adamantane-intercalated LDH particle divided by the thickness of the adamantane-intercalated LDH particle.
