  • Thermally robust, highly porous, and partially fluorinated organic framework with affinity for hydrocarbons, fluorocarbons and freons
    Patent number: 9475777
    Abstract: Porous partially fluorinated materials which bind aliphatic and aromatic hydrocarbons, fluorocarbons and freons with high weight adsorption capacities are provided. Such compounds may be used in separation of materials by exclusion such as selective separation of isomers of xylene.
    Type: Grant
    Filed: May 8, 2015
    Date of Patent: October 25, 2016
    Assignee: UNIVERSITY OF HOUSTON SYSTEM
    Inventors: Ognjen {hacek over (S)} Miljanić, Teng-Hao Chen, Ilya Popov, Watchareeya Kaveevivitchai, Olafs Daugulis

  • Copper-catalyzed C—H bond arylation
    Patent number: 8952207
    Abstract: The present invention is a one-step method for efficiently converting carbon-hydrogen bonds into carbon-carbon bonds using a combination of aryl halides, a substrate, and a copper salt as catalyst. This method allows faster introduction of complex molecular entities, a process that would otherwise require many more steps. This invention is particularly relevant for the organic synthesis of complex molecules such as, but not limited to, pharmacophores and explosives.
    Type: Grant
