Are Zr6-Based MOFs Water Stable Linker Hydrolysis vs. Capillary-Force-Driven Channel Collapse

Abstract

Metalorganic frameworks (MOFs) built up from Zr6-based nodes andmulti-topic carboxylate linkers have attracted attention due to theirfavourable thermal and chemical stability. However, the hydrolyticstability 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 inH2O, but collapse during activation from H2O. Importantly, this frameworkcollapse can be overcome by utilizing solvent-exchange tosolvents exhibiting lower capillary forces such as acetone.
