AB A complete experimental and theoretical study has been carried out for aromatic and quinoidal perylene-based bridges, either substituted with bis(diarylamine) or bis(arylimine) groups. The through-bridge inter-redox site electronic couplings (VAB) have been calculated, for their respective mixed-valence radical cation and radical anion species. The unusual similitudes of the resulting VAB values for the given structures reveal the intervention of molecular shapes with balanced semi-quinoidal/semi-aromatic structures in the charge delocalization. An identical molecular object equally responding to the injection of positive or negative charges is rare in the field of organic πconjugated molecules. However, once probed herein for perylene-based systems, it can be extrapolated to others πconjugated bridges. As a result, this work opens the door to the rational design of true ambipolar bulk and molecular conductors.
