Dynamic Calcium Metal–Organic Framework Acts as a Selective Organic Solvent Sponge

Abstract

Herein, we present a Ca-based metal-organic framework named AEPF-1, which is an active and selective catalyst in olefin hydrogenation reactions. AEPF-1 exhibits a phase transition upon desorption of guest molecules. This structural transformation takes place by a crystal to crystal transformation accompanied by the loss of single-crystal integrity. Powder diffraction methods and computational studies were applied to determine the structure of the guest-free phase. This work also presents data on the exceptional adsorption behavior of this material, which is shown to be capable of separating polar from nonpolar organic solvents, and is a good candidate for selective solvent adsorption under mild conditions.

Structure-Property of Metal Organic Frameworks Calcium Terephthalates Anodes for Lithium-ion Batteries

“…There are limited reports on the structure-properties of these MOFs as electrode materials for batteries [15][16][17][18]. Poizot and coworkers find that isomeric effect in dilithium (2,3-dilithiumoxy)-terephthalate compound (Li 4 C 8 H 2 O 6 ) offers a voltage gain [19].…”

Insight into Lewis Acid Catalysis with Alkaline‐Earth MOFs: The Role of Polyhedral Symmetry Distortions

“…As we have already demonstrated in previous works,14–16, 21 topological analyses become crucial when the details of rather complicated networks matter to explain their properties. We realised that the crystal topology can address the analyses of the most subtle—but often the most important—features in MOF networks, even more for alkaline‐earth frameworks, for which rod packing of inorganic secondary building units (SBUs)22 is often described.…”

Towards Inorganic Porous Materials by Design: Looking for New Architectures

“…AEPF1-dry (Figure 3.b) shows a high adsorption capacity for acetonitrile and acetone, and a very low one for aromatic solvents (benzene, toluene), with no sorption observed for aliphatic organic solvents. [ 40 ] This behavior makes this material a good candidate for selective solvent adsorption in mixed liquids in mild conditions.…”
