Abstract: Perylene bisimide radical anion (A) as salt, preferably as tetrabutylammonium salt, or as salts with other cations as counter ions and lithium, sodium, potassium, rubidium, cesium salt or simple ammonium salt, mono-, di- and trialkylammonium salt or hydrogen ion, hydronium ion or other hydrated proton or protonated forms, is new. Perylene bisimide radical anion (A) of formula (5), (6) or (7) as salt, preferably as tetrabutylammonium salt, or as salts with other cations as counter ions and lithium, sodium, potassium, rubidium, cesium salt or simple ammonium salt, mono-, di- and trialkylammonium salt or hydrogen ion of formula (H+>), hydronium ion of formula (H3O+>) or other hydrated proton or protonated forms, is new.

Provided that the substituents are linked in pairs, in order to avoid the carrying of free valencies of methine groups and/or quaternary carbon-atoms, to form a ring, e.g. cyclohexane ring. An independent claim is included for the preparation of (A). [Image] [Image] [Image].
