Conjugated Copper–Catecholate Framework Electrodes for Efficient Energy Storage

A conjugated copper(II) catecholate based metal-organic framework (namely Cu-DBC) was prepared using a D2 -symmetric redox-active ligand in a copper bis(dihydroxy) coordination geometry. The π-d conjugated framework exhibits typical semiconducting behavior with a high electrical conductivity of ca. 1.0 S m-1 at room temperature. Benefiting from the good electrical conductivity and the excellent redox reversibility of both ligand and copper...
