Thermodynamic redox potentials of reactive mono-and multiple charged cations of aromatic systems can be accurately determined by cyclic voltammetry by using solvents such as S02 or CH2C12, a sophisticated sample preparation technique, low temperatures, and an appropriate time scale in the experiment. Theseconditions allow inter alia the measurement, for the first time, of the redox potentials (vs Ag/AgCl) of the reversible mono-, dication (tri-or tetracation) formation of naphthalene (1.67 V), fluoranthene (1.46 V), triphenylene ([di] 2.49 V),,-binaphthyl ([mono] 1.58 V,[di] 1.86 V), benzo [c] benzo-[3, 4] cinnolino [1, 2-o] cinnoline ([tri] 2.75 V), hexamethoxytriphenylene ([tetra] 2.27 V), 5, 5'-dimethyl-2, 2'-bithienyl ([mono] 1.08 V,[di] 1.68 V), and 3, 3'-dimethoxy-2, 2'-bithienyl (0.79 V).
