Inorganic and metal-organic materials, e.g. metal oxides, metal-organic frameworks (MOFs) and metallodrugs are at the forefront of modern materials science. However, syntheses and transformations of such materials are often encumbered with energy-, reagent- and solvent-intense procedures, which threaten to defeat their proposed use in hydrogen storage, carbon dioxide sequestration, light harvesting, etc. This presentation will delineate our work in developing simple, low-energy and largely solvent-free methodologies for transforming and interconverting inorganic and metal-organic structures. We will describe the recently introduced mechanochemical1 techniques2 for the rapid, templated transformations of metal oxides into porous MOFs and metallodrugs.3 We will also address 'accelerated aging',4a novel technique which mimics the natural processes of mineral weathering for the energy- and solvent-reduced assembly of metal-organic materials and allows the solvent-free recognition and spontaneous separation of metals in the oxide form.Besides enabling chemical transformations of metal oxides under mild conditions, the described solid-state methodologies present a unique opportunity to probe the factors controlling the assembly of metal-organic structures, without interferences of solvent, thermal gradients or counterions.1) Fri�cic, Chem.
