Automated Diffraction Tomography for the Structure Elucidation of Twinned, Sub-micrometer Crystals of a Highly Porous, Catalytically Active Bismuth Metal-Organic Framework

摘要

The number of metal-organic framework (MOF) compounds has increased almost exponentially over the last decade as a consequence of their fascinating structures and potential applications.They are composed of inorganic building units, such as metal ions or clusters, which are connected through organic linker molecules to form a porous three-dimensional network. Most of the MOFs are based on rigid polycarbox-ylate linker molecules but a large variety of metal ions, mainly transition-metal ions, have also been incorporated. The chemical and thermal stability of metal carboxylate based MOFs is crucial for potential applications and depends on the metal ions incorporated. In general, metal ions in higher oxidation states lead to more stable structures.
