Abstract:
In from the cold: The Co(III) Fe(II) state of a CoFe Prussian blue analogue undergoes a Co(III) ?Fe(II) →(Co(II) ?Fe(III) )* electron transfer at room temperature when irradiated by visible light (532?nm; see scheme). This property was confirmed using energy-dispersive X-ray absorption spectroscopy at the Co and Fe K-edges of the piezo-induced Co(III) Fe(II) state.
