The generation of novel redox systems under nano-space control is one of the most exciting fields in present inorganic and supramolecular chemistry. The authors have drawn together the newest information on the construction of such novel redox systems using nano-space control of complexation or molecular chain-induced spaces and metal- or self-assembled spaces through combining techniques in coordination, supra-molecular, and biomimetic chemistry. Such design on the nano level produces hybrid conjugated systems composed of transition and synthetic metals, metallohosts, redox-active...
