Luminescent molecular switches based on dicationic P-doped Polycyclic Aromatic Hydrocarbons

We report the efficient synthesis of electron-acceptors based on cationic P-doped polycyclic aromatic hydrocarbons. In particular, exo-skeletal modifications of the p-core were performed and their effect on the optical and redox properties was…
