Post-synthetic modification of metal-organic frameworks by solid-gas ozonolysis

Abstract:

In this thesis we describe the Solid-Gas Ozonolysis approach to modify the chemical functionalization and the porous properties of Metal-Organic Frameworks. First, using ozone, we quantitatively transformed the olefin groups of a UiO-66-type MOF into 1,2,4-trioxolane rings, which we then selectively converted into either aldehydes or carboxylic acids. Then, By carefully selecting mixed-ligand Zr-fcu-MOFs based on organic ligand pairs in which one ligand has ozone-cleavable olefin bonds and the other ligand is ozone-resistant, we were able to selectively break the cleavable ligand via ozonolysis to trigger fusion of micropores into mesopores within the MOF framework.
