Metal organic frameworks (MOFs) are emerging potential materials for catalytic applications. Among them, the honeycomb M2 (dhtp) family, also known as MOF-74 or CPO-27 materials, are characterized Synthesis of Fe3O4@Mg-MOF-74-II nanoparticles: The procedure for preparation of the composite is similar to the synthesis of Fe3O4@Mg-MOF-74 except that the 3,3'-dihydroxy-[1,1'-biphenyl]-4,4'-dicarboxylic acid was used as the ligand. Synthesis of Fe3O4@DOT: The procedure is similar to that of Fe3O4@Mg-MOF-74 without Mg(NO3)2•6H2O. The synthesis of chiral metal–organic frameworks (MOFs) is highly relevant for asymmetric heterogenous catalysis, yet very challenging. Chiral MOFs with MOF‐74 topology were synthesised by using post‐synthetic modification with proline. Vibrational circular dichroism studies demonstrate that proline is the source of chirality.
