摘要
Fabrication of bis(terpyridine)iron(II) complex wires by introduction of a bithiophene-linked bridging ligand (L-BT) on the Au(III) surface is discussed. A comparative study revealed a very small energy gap between the HOMOs of Fe(tpy)(2) and L-BT indicating relatively strong electronic coupling and better electron-transport ability. By cyclic voltammetry and potential step chronoamperometric measurements, the small attenuation factor (beta(d) = 0.010 +/- 0.004 angstrom(-1)) was witnessed.
