The single molecule conductances of a series of bis-2,2':6',2″-terpyridine complexes featuring Ru(II), Fe(II), and Co(II) metal ions and trimethylsilylethynyl (Me3SiC≡C-) or thiomethyl (MeS-) surface contact groups have been determined. In the absence of electrochemical gating, these complexes behave as tunneling barriers, with conductance properties determined more by the strength of the electrode-molecule contact and the structure of the "linker" than the nature of the metal-ion or redox properties of the complex.
已经测定了一系列具有Ru(II)、Fe(II)和Co(II)金属离子以及三甲基甲硅烷基乙炔基（Me3SiC≡C-）或硫甲基（MeS-）表面接触基团的双-2,2':6',2″-三联吡啶配合物的单分子电导。在没有电化学门控的情况下，这些配合物表现为隧穿势垒，其电导特性更多地由电极-分子接触的强度和“连接体”的结构决定，而非配合物的金属离子性质或氧化还原性质。
