A delocalized quasi-free π electron is present in the radical cation of 1, according to ESR and measurements with a SQUID magnetometer. Electrochemical oxidation of 1 at a Pt wire produced salts of 1⊕ in the form of blue-green single crystals. Based on cyclic voltammetric data, the dication 12⊕ is also relatively stable, perhaps with a triplet ground state.
