Abstract

Metal-organic frameworks (MOFs) built up from Zr₆-based nodes and multi-topic carboxylate linkers have attracted attention due to their favourable thermal and chemical stability. However, the hydrolytic stability of some of these Zr₆-based MOFs has recently been questioned. Herein we demonstrate that two Zr₆-based frameworks, namely UiO-67 and NU-1000, are stable towards linker hydrolysis in H₂O, but collapse during activation from H₂O. Importantly, this framework collapse can be overcome by utilizing solvent-exchange to solvents exhibiting lower capillary forces such as acetone.
