  1. Cyclic voltammetry experiments indicated that most of the redox processes were reversible (for details, see Supplementary Information). Working electrode: glassy carbon, counter electrode: Pt wire, reference electrode: Ag/AgCl.
  2. aPotentials (V) were determined vs. ferrocene/ferrocenium ion by differential pulse voltammetry.
