Description	Single-molecule conductance in a series of extended viologen molecules was measured at room temperature using a goldmoleculegold scanning tunneling microscopy break junction arrangement. Conductance values for individual molecules change from 4.8 1.2 nS for the shortest compound to 2.9 1.0 nS for the compound with six repeating units and length of 11 nm. The latter value is almost 3 orders of magnitude higher than that reported for all-carbon-based aromatic molecular wires of comparable length. On the basis of the length of the molecules, an attenuation factor of only 0.06 0.004 nm-1 (0.006 0.0004 Å-1) was obtained. To the best of our knowledge, this is the smallest value reported for the conductance attenuation in a series of molecular wires.
