Exposure to ambient air or humid oxygen increases the electronic conductivity of a new vanadylcobalt Prussian blue analogue by up to 5 orders of magnitude, where the exposure time tunes the conductivity. We probed the mixed-valence nature of the oxidized framework using electrochemistry, electronic spectroscopy, and electron paramagnetic resonance. Notably, the material maintains its porosity before and after oxidation.
