The formal potentials for hypericin are measured in dimethylsulfoxide using cyclic voltammetry. Two reversible one‐electron reductions and a more poorly defined multielectron oxidation are observed. The formal potentials for these processes are consistent with the visible spectrum of hypericin and they indicated that hypericin is both a good oxidizing agent and a good reducing agent in the excited state.
