Drastic Enhancement of Catalytic Activity via Post-oxidation of a Porous MnII Triazolate Framework

MnIII is a powerful active site for catalytic oxidation of alkyl aromatics, but it can be only stabilized by macrocyclic chelating ligands such porphyrinates. Herein, by using benzobistriazolate as a rigid bridging ligand, a porous MnII azolate framework with a nitrogen‐rich coordinated environment similar to that of metalloporphyrins was synthesized, in which the MnII ions can be post‐oxidized to MnIII to achieve drastic increase of catalytic (aerobic) oxidation performance. Later could be better: A robust and redox‐active, porous coordination framework has been designed and constructed, in which the MnII ions on the pore surface can be post‐oxidized to form unstable MnIII sites with drastically enhanced activity for catalytic oxidation of alkylaromatics (see figure; TBHP=tert‐butyl hydroperoxide).
