a The charge densities derived from integration of the immersion current transients against the applied potentials of Au(111) in 50 mM NaClO4 without or with 0.1 mM 4-MTBA. Error bars represent standard deviation obtained from different experiments. b Typical conductance traces of single-molecule conductance measurements obtained on Au(111) substrate in 0.1 mM 4-MTBA + 50 mM NaClO4 solution with potential control at 0 V or −0.5 V. c 1D conductance histograms of 4-MTBA obtained in different electrolyte solutions, and 2D conductance-displacement histograms of 4-MTBA in 50 mM NaClO4 solution obtained at d 0 V and e −0.5 V, respectively. The counts are normalized by the number of conductance traces used. All potentials are specified with respect to Pt.
