Methods to produce glass forming metal–organic frameworks (MOFs) rely on solvothermal syntheses which have high energy requirements, low yields and large teratogenic solvent usage. We present mechanochemical methods to overcome these issues.

Current methodologies to produce glass forming metal–organic frameworks (MOFs) rely on non-scalable solvothermal syntheses which have high energy requirements, relatively low yields and large tetratogenic solvent usage. Here we use a mechanochemical method to produce glass-forming MOFs, ZIF-62 and ZIF-UC-5, in 30 minutes at room temperature, using microlitre quantities of solvent and stoichiometric amounts of organic linkers. This method facilitates the accurate synthesis of ZIF-62 structures containing both Co and Zn, allowing the effect of metal-ion dopant upon melting temperature to be studied for the first time. Further to this, we present variable organic linker ratio series of IF-62 and of ZIF-UC-5. The specific composition of the materials in the series is made possible by the mechanochemical method. We also present a greener solvothermal method to form ZIF-62, which is capable of producing crystalline materials of suffcient quality for single crystal diffraction experiments.<br><br>

We propose a novel solvent-free conversion strategy of Pt–ZnO to Pt-ZIF-8. This synthesis strategy may facilitate the discovery of MMOFs that have not been reported previously.
