What is the poison? Three different condensation reactions were chosen as model reaction to determine the nature of the poisons causing structural instability (see picture), and varied product selectivity for two related metal–organic framework catalysts, Fe(BTC) and synthetic MIL-100(Fe). Undesired intermediates or byproducts were found to block the pores, whereas phenolic substrates could substitute the metal ligands thus destabilizing the catalyst structure.
