The reported surface areas and pore volumes were calculated using Materials Studio. Specifically, a VdW Surface is created by intersecting the Van der Waal (VdW) radii of the framework and a probe solvent radius. By evaluating this throughout the pore, one can recreate a VdW surface and calculate its corresponding surface area. For these calculations, a solvent radius of 1.445 Å is used, based on the kinetic diameter of Hydrogen of 2.89 Å. An example VdW surface is overlaid on MSUCOF-1 and its metalated case in Figure .
