In this study, we fabricated a cross-linked single-molecule junction between two Au electrodes and four molecules with different bonding types, and measured the electrical conductivity. By combining the results with the calculation of the potential energy of the junction, the relationship between the binding strength between the metal and the single molecule and the electrical conductivity of the single molecule was clarified. In order to obtain higher structural and electrical stability at the metal-molecule interface, we found that it is necessary to design the molecule including not only the anchor group but also its adsorption site.
