摘要: The single molecule conductances of a series bis-2,2′:6′,2″-terpyridine complexes featuring Ru(II), Fe(II), and Co(II) metal ions trimethylsilylethynyl (Me3SiC≡C−) or thiomethyl (MeS-) surface contact groups have been determined. In the absence electrochemical gating, these behave as tunneling barriers, with conductance properties determined more by strength electrode–molecule structure “linker” than nature metal-ion redox complex.
