Turning briefly to the TGA of the introduced samples, none of them show a pronounced solvent loss at low temperatures. This is due to our post-synthesis activation of the MOFs, a common procedure. If we compare the shape of the TGA curves with literature, the features discussed in Results are all typical. As we are proposing a new way to evaluate MOF stoichiometry, it is instructive to compare our results with existing methods. The methods of Shearer and Abánades Lázaro are based on TGA, although NMR does make an appearance when treating MTV-MOFs or when organic modulators are used. First we will briefly introduce the mathematics of both methods, following their notation to facilitate direct comparison.
