Constructing new porous metal-organic frameworks (MOFs) is receiving considerable attention worldwide and is a ¿hot topic¿ owing to their potential for gas storage, separation, and purification. We request 6 days on WISH to study the preferred binding sites and locations of adsorbed gas molecules (C2D2, C2D4, C2D6, C3D4, C3D6, C3D8, NO2, NO, and N2O) within two porous MOF materials as a function of different gas loadings. The high resolution and large d-spacing capabilities of WISH make it ideal for analysing the precise locations of gas molecules within these porous MOFs and their preferred orientation with respect to the functional groups on the pore surface.
