Validation and Mechanistic Studies of the Headspace Effect in MOF Synthesis
Angewandte Chemie, Volume 137, Issue 12, March 17, 2025.For a fixed vessel volume, the rate of metal–organic framework formation is shown to depend on the amount of solution employed. This headspace effect is demonstrated to arise only in the presence of oxygen. Mechanistic studies demonstrate that oxygen reacts with the formamide solvent and contributes to nitrosamine side products.
