The Impact

In this communication, we report the straightforward<br>synthesis of unprecedented electron-acceptors based on dicationic P-containing PAHs (Polycyclic Aromatic Hydrocarbons) where two phosphoniums are connected through various PAHs backbones. The impact of pi-extension on both the optical and redox properties is investigated using a joint experimental/theoretical approach.<br>Finally, (spectro)-electrochemical studies prove that these<br>compounds possess three redox states and EPR studies confirms the in situ formation of an organic radical.
