Advantageously, zeolite-net-like MOFs of the subject invention are porous and contain large functional cavities, which is useful for encapsulating large molecules.Type: GrantFiled: April 24, 2006Date of Patent: April 9, 2013Assignee: University of South FloridaInventors: Mohamed Eddaoudi, Yunling Liu

Patent number: 8410185Abstract: A porous polymer, poly-9,9?-spirobifluorene and its derivatives for storage of H2 are prepared through a chemical synthesis method. The porous polymers have high specific surface area and narrow pore size distribution. Hydrogen uptake measurements conducted for these polymers determined a higher hydrogen storage capacity at the ambient temperature over that of the benchmark materials. The method of preparing such polymers, includes oxidatively activating solids by CO2/steam oxidation and supercritical water treatment.Type: GrantFiled: November 16, 2011Date of Patent: April 2, 2013Assignee: Uchicago Argonne, LLCInventors: Luping Yu, Di-Jia Liu, Shengwen Yuan, Junbing Yang
