A one‐component acceptor‐donor‐acceptor compound based on a rigid TCNQ‐σ‐TTF‐σ‐TCNQ system (see picture) exhibits a unique case of both intramolecular charge and electron transfer through space that is strongly dependent on the polarity of the medium. The strong dependence of the ground‐state electronic structure on the solvent polarity provides an unprecedented case of solvatochromism.
