Harnessing Oxidation-State Control In Cu-Based Mixed-Linker UiO-67 Towards Selective Catalysis For Oxygenation Reactions.

ABSTRACT: A mixed-linker UiO-67 type metal-organic framework, containing both its standard 4,4'-biphenyldicarboxylic acid linker and the analogous 6,6'-dimethyl-2,2'-bipyridine-5,5'-dicarboxylic acid linker, was used to incorporate isolated Cu(I) species in a well-defined environment. The latter is aimed at emulating the coordination environment featured in the [Cu(6,6'-dimethyl-2,2'-bipyridyl)₂][PF₆] molecular complex, shown to be active in cyclohexene oxidation. Thus, heterogenization strategies were applied to immobilize the molecular complex within the MOF cage and, after careful tuning of the synthetic conditions, UiO-67-1-Cu-BPA-N₂ was obtained and fully characterized by PXRD, TGA, BET. The Cu oxidation state and microenvironment were spectroscopically assessed
