Sažetak
Metal-organic frameworks (MOFs) are nanoporous molecular networks with high structural and chemical diversity. MOFs show enormous potential due to the high tunability of their physicochemical properties through structural changes. Solid-state nuclear magnetic resonance (ssNMR) and electron paramagnetic resonance (EPR) spectroscopy provide information on the structure and dynamics of MOFs. They complement other spectroscopic and diffraction analyses in the search for an understanding of the relationship between structure and function in MOFs. Ball milling has been used for the stoichiometrically controlled formation of bimetallic MOF-74[1] and amorphization of MOF-74 materials.[2, 3] Here, bimetallic MOF-74 materials consisting of diamagnetic zinc (II) and paramagnetic copper (II) metal nodes in a 1:1 ratio, were prepared by different mechanochemical approaches and from different polymeric precursors. To find out their differences and how the introduction of defects and the collapse of the porous structure of MOF by mechanochemical amorphization affects their properties, we studied them by magnetic resonance spectroscopy (ssNMR and EPR). Synthesized crystalline materials are indistinguishable by powder X-ray diffraction, while ssNMR and EPR spectroscopy along with other analyses revealed different distributions of metals in the MOFs.[4] ; [1] G.
