Thermally and Light‐Induced Valence Tautomeric Transition in a Dinuclear Cobalt–Tetraoxolene Complex

Abstract

Getting in tune: A material that undergoes valence tautomerism was obtained by tuning the electronic properties of a cobalt–polyoxolene complex (shown schematically) which contains a tripositive metal ion acting as an ancillary counterpart. The tautomerism, which can be thermally or light induced, is quantitative upon irradiation at 617 nm.
