    • From the redox potentials obtained from cyclic voltammograms (CVs) of the metal strings, we believe that their oxidation states remain unchanged after chemisorption onto the Au(111) substrate. The Fermi energy of Au(111) is 5.31 eV, (Handbook of Chemistry and Physics, 67th ed.; CRC Press: Boca Raton, FL, 1986; p E-89) corresponding to 0.81 V versus NHE (Bard, A. J.; Faulkner, L. R. Electrochemical Method, 2nd ed.; Wiley: New York, 2001; p 54). For the one-electron oxidized compounds to be reduced by Au(111), their redox potential should be more positive than 0.81 V versus NHE, CVs (Figure S6) show that the one-electron redox potentials for penta-nickel, penta-cobalt, and penta-chromium complexes are respectively 0.573, 0.269, and 0.192 V versus NHE, at least 237 mV smaller than the Fermi energy of Au(111). Reduction of the one-electron oxidized metal strings by Au(111) substrate is, therefore, not favorable.
