Drastic Enhancement of Catalytic Activity via Post‐oxidation of a Porous Mn II Triazolate Framework

Mn III 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 Mn II azolate framework with a nitrogen‐rich coordinated environment similar to that of metalloporphyrins was synthesized, in which the Mn II ions can be post‐oxidized to Mn III to achieve drastic increase of catalytic (aerobic) oxidation performance.
