Synthesis and post-synthetic modification of UiO-67 type metal-organic frameworks by mechanochemistry

Abstract

Herein, we report the synthesis of zirconium metal-organic frameworks by a mechanochemical route. The frameworks are obtained by the coordination of a zirconium cluster with the biphenyldicarboxylic acid linker to obtain UiO-67 or with the iso-structural 2,2′-bipyridine-5,5′-dicarboxylic acid to access to a functional MOF (UiO-67-bpy). In a second mechanochemical reaction, it has been possible to coordinate by post-synthetic modification a copper salt on each bipyridine site (UiO-67-bpy-Cu). Both materials exhibit crystallinity and porosity (up to 750 m2/g) showing the possibility to get access to elaborated materials in a cleaner way than the classical solvothermal route in DMF.
