One-dimensional conductive polymers are attractive materials because of their potential inflexible and transparent electronics. Despite years of research, on the macro- and nano-scale,structural disorder represents the major hurdle in achieving high conductivities. Here wereport measurements of highly ordered metal-organic nanoribbons, whose intrinsic (defectfree)conductivity is found to be 104Sm1, three orders of magnitude higher than that of ourmacroscopic crystals. This magnitude is preserved for distances as large as 300 nm. Abovethis length, the presence of structural defects (B 0.5%) gives rise to an inter-fibre-mediatedcharge transport similar to that of macroscopic crystals. We provide the first direct experimentalevidence of the gapless electronic structure predicted for these compounds.Our results postulate metal-organic molecular wires as good metallic interconnectorsin nanodevices.
