Case 1. There were MOFs that showed trivial surface area (limited uptake to N2), but at the same time exhibited considerable uptake to other gases (like CO2 or H2), or when the PXRD of the activated sample are still showing peaks (sometimes with slight shifts). These MOFs might possess a breathing behavior or crystal-to-crystal phase transition, and absence of nitrogen uptake is not an evidence for structural degradation upon solvent removal.
