Graphical Abstract
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.
