While the interface conductance is expected to drop exponentially as the distance between the conjugated π-system of the molecular electronic device and the metal surface increases, 3 the “alligator clip” most widely used to attach molecular wires to metal substrates, the thiol group, 4 unavoidably introduces an extra atom and a covalent bond into the molecule-to-metal gap. In an attempt to alleviate this problem, we utilized the well-established reactivity of ...
