Porous functional metal-organic framework (MOF) materials show great potential for high capacity gas storage and separation. We seek to develop new materials for carbon capture and hydrocarbon separation and request 4 days on WISH to study the preferred binding sites and locations of adsorbed gas (CO2, C2D2, C2D4 and C2D6) molecules within an amide-functionalised MOF showing record-high adsorption capacities of CO2 and light hydrocarbons. The high resolution, low background and large d-spacing capabilities of WISH make it ideal for analysing the precise locations of gas molecules (particularly for hydrocarbon molecules) within this porous MOF and to define the preferred orientations of molecules with respect to the binding sites (in this case amide groups) on the pore surface. This study will reveal key insights into the excellent storage capacity of CO2 and light hydrocarbons in this MO
