Metal-organic frameworks (MOFs) are among the most attractive porous materials known today. Their high surface-to-mass ratio makes them extremely useful in many processes, from gas sorption, storage and separation, to catalysis, drug delivery and heat exchange. Typically they are modified post-synthesis (PSM) to optimise their chemical functionality and/or pore surface to a specific application. We propose a new approach to PSM.
Our researchers have developed a new process for performing PSM MOFs, the spray drying of a MOF and a reagent to form a covalent bond.
The new process requires very short reaction times, mild conditions and is scalable to produce large quantities of modified MOFs. Despite such short reaction time covalent bonds are created with a high conversion efficiency.
What is more, the process allows for obtaining modified MOFs in continuous flow, making the method convenient for large scale industrial production.
