Upon increasing the applied bias, our results show an increase in the probability of the molecular sub-population corresponding to the low conductance feature. This phenomenon is attributed to the voltage-dependent behavior of electrostatic interactions forming junction contacts between the charged molecular backbone and the gold electrode . Taken together, our results clearly demonstrate the ability to control the distribution between charge transport pathways simply by changing the applied bias (Fig. ). Our multicomponent synthetic approach enables facile elucidation of the role of molecular substitutions, side groups, and counterions on molecular charge transport. Ladders bearing aromatic (C6H5, p-OMeC6H4) or aliphatic ( n Pr) groups exhibited similar average end-to-end conductance values corresponding to the high conductance feature (Fig. and Supplementary Fig. ). Interestingly, the high conductance feature remained nearly constant for L2 regardless of the complexing anion (F -, Cl -, BF4 -, PF6 -; Supplementary Figs. and). However, prior work reported that molecular charge transport in viologen-based molecules is highly dependent on the chemical identity of the counterions . DFT simulations showed that differences in conductance for viologen molecules were driven by changes in the torsion angles of the molecular backbone, which sensitively depend on counter anion identity .
