Theme:
Metal-organic frameworks (MOFs) are compounds consisting of metal ions or clusters coordinated to organic molecules to form one-, two-, or three-dimensional structures that can be porous. Covalent Organic Frameworks (COFs) are porous, and crystalline, and made entirely from light elements (H, B, C, N, and O). MOF/COFs are stirring great interest, by virtue of their large variety of structure types and chemical composition as well very high surface area, which lead to various applications in gas storage (hydrogen, methane), carbon capture, gas separation, catalysis, sensors. Accurate structural knowledge is key to the understanding of the applicability of these materials.
At this workshop, we will discuss new x-ray techniques that have provided unique information in this field. (1) Grazing incidence wide angle x-ray scattering (GiWAXS), which can determine the crystallinity and crystallographic orientation of MOF/COF thin films, inaccessible by transmission techniques; (2) Measurement of gas absorption using SAXS to track and map the ordering of adsorbate molecules, thus offering insights into the selectivity and uptake capacity of the adsorption process.; (3) Single-crystal diffraction or power XRD at high pressure, which is critical to understand the structural response of MOFs to applied pressures; (4) Soft x-ray spectroscopy, which can explore electronic structure of MOF/COF upon gas absorption.
We will also invite scientists from both universities and industry to discuss the challenges they face in characterization of MOF/COF for the purpose of making real-world applications.
