Functionalized 4,4′-biphenyldicarboxylic acid molecules with additional amine, alkyne, azide or nitro groups were prepared and applied in the synthesis of novel metal-organic frameworks and mixed-linker metal-organic frameworks isoreticular to DUT-5. The properties of the frameworks could be tuned by varying the number of functional groups in the materials and the amine groups were employed in post-synthetic modification reactions without changing the framework structure or significantly decreasing the porosity of the materials. Various functionalized 4,4′-biphenlydicarboxylic acids were prepared and applied in the synthesis of single- and mixed-linker DUT-5 frameworks. The NH 2 -containing materials were used for post-synthetic modification.
