9. The concentration is fixed to 1 mM for all studies presented in this work. In addition, we have tried other solvents, such as phenyloctane or dodecane, and find similar results.

11. We divide the total histogram by the number of traces used to generate it to ensure that when we are comparing histograms with different molecules the counts represents actual additional features, such as steps in individual traces, when compared with histograms from clean gold. This is equivalent to comparing histograms of different molecules constructed from an equal number of traces.

17. For the shorter alkanes, a faint secondary peak is also visible at twice the conductance value of the primary peak. This could be due to the trapping of two molecules in parallel between the electrodes.
18. For the 1,7-heptanediamine and 1,8-octanediamine data, we subtract the gold histogram from our data prior to fitting a peak because the conductance of these molecules is close to our detection limit. This adds a large error to the conductance value, as shown in Figure 3b.
