    • 1/2 = +0.41 V (Fig. S1). On sweeping further toward negative direction, a small reduction peak corresponding to peak (II) is observed not accompanying with distinct peak (I). However, on bulk electrolysis (reoxidation) of the reduced solution at +0.7 V, the cyclic voltammogram and UV-vis spectrum of this solution coincided with those of the original solution before the electrolysis at -0.4 V. Multi-sweep cyclic voltammetry was also conducted for 1 - 7. The first sweep shows the features as described above. Waves I, II, III, and IV for 4 appeared at +0.15, -0.06, +0.00, and +0.45 V, respectively. In the second sweep toward negative direction, the reoxidized species were reduced mainly at -0.06 V (wave II), though a new small peak (V) coupled with peak (IV) appeared at +0.37 V. These features are practically unchanged on further cyclic scans. The relative peak height of wave V and I depends significantly on the bridging amino acids. The complex 7 and 2 show no distinct peak (V), while these complexes show distinct wave I. The peak height of the redox couple (IV/V) increases and that of wave I decreases in the order of 7, 2, 3, 5, 6, 1, and 4. The trend is similar to the increasing peak height of wave IV in the presence of triethylamine.
