Abstract

Abstract: Porous molecular cages have a characteristic processability arising from their solubility, which allows their incorporation into porous materials. Attaining solubility often requires covalently bound functional groups that are unnecessary for porosity and which ultimately occupy free volume in the materials, decreasing their surface areas. Here, a method is described that takes advantage of the coordination bonds in metal–organic polyhedra (MOPs) to render insoluble MOPs soluble by reversibly attaching an alkyl‐functionalized ligand. We then use the newly soluble MOPs as monomers for supramolecular polymerization reactions, obtaining permanently porous, amorphous polymers with the shape of colloids and gels, which display increased gas uptake in comparison with materials made with covalently functionalized MOPs. Abstract : Durch die reversible Koordination von sperrigen Liganden an die axialen Koordinationsstellen unlöslicher Metall‐Komplexe können metallorganische Polyeder in Lösung gebracht und über supramolekulare Polymerisationsreaktionen in mikroporöse Polymere eingebaut werden.
