Patent number: 10968284Abstract: The present invention is a multilayered composite comprising porous metal oxide particles that are covalently bonded by way of inorganic ether groups to one or more sites of a first polyhydroxyl-functionalized polymer. This first polymer is in turn covalently bonded by way of inorganic ether groups to one or more sites of a second polyhydroxyl-functionalized polymer. The multilayered composites can be prepared by contacting porous inorganic-oxide particles with a sufficient amount of OH-reactive crosslinking agent to form metal oxide particles imbibed with the crosslinking agent, and then contacting the inorganic-oxide particles with a solution of polyhydroxyl-functionalized polymer under reactive conditions.Type: GrantFiled: February 2, 2017Date of Patent: April 6, 2021Assignees: The Regents of the University of California, Dow Global Technologies LLC, Rohm and Haas CompanyInventors: Joseph Jankolovits, Alexander S. Katz, Oz M. Gazit, James C. Bohling, John A. Roper, III

Patent number: 9266915Abstract: The present invention is directed to the synthesis of novel stable open metal clusters by selective oxidation of bound ligands. The synthesis comprises, for example, using an amine based oxidant for decarbonylation of specific carbonyl ligands. The synthesis can also comprise further removal of a bound amine group by an acid. The resulting metal cluster contains a coordinatively unsaturated site comprising a carbonyl vacancy. The resulting metal cluster can be used as a catalyst in a variety of chemical transformations.Type: GrantFiled: June 4, 2015Date of Patent: February 23, 2016Assignees: Chevron U.S.A.
