    abstract = {Non-covalent inclusion of small acid and base molecules (CHCOOH
               and NEt) in an imine structure based on micrometre COF-300
               crystals and amorphous nanoparticles results in the facile
               modulation of their acid-base properties. Such a strategy results
               in the triggering of acidic/basic catalytic activity of the
               otherwise inactive materials towards ring-opening epoxide and
               Knoevenagel condensation reactions. For both reactions, amorphous
               nanoparticles are better catalysts than micrometre crystals as
               they exhibit a higher external surface area. The found activities
               and stability of this supramolecular functionalization are
               modulated by confinement effects, which are rationalized with the
               help of DFT calculations. All results obtained suggest that the
               reactions catalysed by these functionalized materials occur
               confined to pores closer to the material surface, which makes
               size-discrimination phenomena possible, and explains the major
               activity of the nanoparticulated material.},
