Abstract Two systems using bottom-up fabrication of molecular wires on an electrode surface are described. The first system involves films composed of linear and branched wires of metal complex oligomers, which were prepared using stepwise complexation of metal ions with bis- and tris-tpy (tpy = 2,2′:6′,2″-terpyridine) ligands, respectively, on tpy-terminated SAM on gold. This method allows the formation of desired numbers of polymer units and of desired sequences of hetero-metal structures in… Expand
