Summary:Electrically conductive layered metal–organic frameworks, regardless of the metal or chelating atom identity, exhibit phase-dependent catalytic activity for O 2 electroreduction. Triphenylene ligands hexasubstituted with amino or phenol groups afford two phases of electrically conductive layered two-dimensional metal–organic frameworks upon reaction with various metals. Regardless of the identity of the metal or chelating atom, π-stacking within the MOF layers is essential to achieve high electrical conductivity, redox activity, and catalytic activity.
