Rücktitelbild: Mixed‐Valence CuI/CuIII Metal–Organic Frameworks with Non‐innocent Ligand for Multielectron Transfer (Angew. Chem. 50/2023)

Two novel Cu(I)/Cu(III) mixed‐valence metal–organic frameworks (MOFs) are synthesized from Cu(II) and redox‐non‐innocent ligand 1,4‐dicyano‐2,3,5,6‐tetrahydroxybenzene, as reported by Watchareeya Kaveevivitchai, Teng‐Hao Chen et al. in their Research Article (e202312494). The coordination between the mixed‐valence metal and redox‐non‐innocent ligand promotes through‐bond charge transfer between Cu metal sites, leading to semiconducting behavior and multielectron transfer.
