The cyclic voltammogram of complex 6 shows one successive reversible one-electron redox wave corresponding to the oxidation of the Ruthenium moiety and peak-to-peak separations are smaller than 59 mV(ideal value of one electron transfer with diffusing controlling). In addition, the peak currents are linear to scan rate, i.e., i £\ V. This observation is corresponding to the electrochemical property of SAM, and we would like to suggest that the electron transfer process in the electrochemical measurements is direct controlling. Furthermore, we synthesized a nano-material by using of redox stable Ru(II)-Terpyridyloctanethiol attached to gold cluster (complex 7). The clusters are stable in air, soluble in nonpolar organic solvents and the characters could be examining by traditional chemical instruments such as NMR, UV/Vis, TEM. Finally, complex 7 seif-assembled on gold electrode (complex 8). This observation is corresponding to the electrochemical property of SAM, and we would like to suggest that the electron transfer process in the electrochemical measurements is direct controlling. we would like to suggest that the complex 5 has bi-functionalized property.
