Happy marriage : For the first time, a fused TCNQ–TTF–TCNQ triad has been synthesized and structurally characterized. Strong bending is observed in both the TTF bridge and the benzo‐TCNQ moieties, which prevents good packing for intermolecular charge transfer. The Vis/NIR and VT‐EPR studies of the mixed‐valence derivative of the triad indicate that the electrons are moving from one acceptor moiety to the other through the donor TTF bridge.
