Electronic conductivity of molecular wires is a critical fundamental issue in molecular electronics. π-Conjugated redox molecular wires with a superior long-range electron-transport ability are constructed on a gold surface through the stepwise ligand–metal coordination method. H. Nishihara et al. investigate the influences on the electron-transfer rate constant by the chemical structure of molecular wires and the terminal redox units, temperature, electric field, and electrolyte concentration. The results indicate that facile sequential electron hopping between neighboring metal–complex units within the wire is responsible for the high electron-transport ability.
