C.T.P.S. received a fellowship from the National Council for Scientific and Technological Development ? CNPQ (process 202064/2014-0). J.T.H. thanks the National Science Foundation for support of work at Northwestern University through grant 1604890 in the SusCHEM program. This work made use of the Integrated Molecular Structure Education and Research Center (IMSERC) and the J.B. Cohen X-Ray Diffraction Facility at the Materials Research Center (Northwestern University). Elemental analysis was performed at the NU Quantitative Bio-element Imaging Center. We gratefully acknowledge Prof. Omar K. Farha for many useful discussions. Finally, we warmly congratulate Prof. Omar Yaghi on his recognition via the 2018 Wolf Prize for pioneering research in the field of metal-organic frameworks.

N2 - Here we report a new highly microporous zirconium phosphonate material synthesized under solvothemal conditions. The specific Brunauer-Emmett-Teller (BET) surface area of the “unconventional metal−organic framework” (UMOF) is measured to be ∼900 m2/g, after following an appropriate activation protocol. Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) shows that the material bears a free −OH functionality on the phosphonate linker that may interact with CO2. CO2 adsorption isotherms were collected and a measured heat of adsorption of 31 kJ/mol was obtained. In addition, adsorption isotherms of CO2, N2, and CH4 at 298 K combined with Ideal Adsorbed Solution Theory (IAST) show that the material can be expected to display high selectivities for uptake of CO2 versus N2 or CH4.
