Abstract
We report electrochromism of M-MOF-74 (M=Mg, Mn, Co or Zn), a honeycomb nano-framework in which hexagonally packed one-dimensional
arrays of metal cations are coordinated with 2,5-Dihydroxyterephthalic acid linker. Raman spectroscopy upon electrochemical doping combined with density functional theory calculations reveals redox reactions of the linker while the metal cations stay divalent as
probed by X-ray photoemission spectroscopy. Excellent adhesion of the MOFs to glass allows synthesis of quality thin films to be implemented into electrochromic devices that exhibit promising colour contrast and durability.
