In DMF KC104 2.0 x 10-2 F the discharge begins at about -1.90 V. If the same solution contains also 2.0 Γ 10 -4 F CH/C1COOH the discharge begins at about -1.75 V.
To whom correspondence should be addressed. \*\* In the all purified samples of compound (I) the reported s presence of a small amount (ca. 0.5~) of 1-oxy-l'-hydroxy-2,2'-diphenyl-3,3'-bi-indole radical should not introduce any complication in our experiments.
