Table 2. Most probable conductance values (second column), standard deviation (third column) and full-width at half maximum FWHM (last column) obtained from fitting the data of 1D histograms to log-normal distributions for molecules 4–6 a .
| Molecule | G (G0) | Std (G0) | FWHM (dec) |
| S-CCM-BF2 (4) | 4.3 × 10–4 | 1.1 × 10–4 | 0.9 |
| Thph-CCM-BF2 (5) | 4.3 × 10–4 | — | 0.6 |
| MeS-dbm-BF2 (6) | 4.7 × 10–4 | 6.4 × 10–5 | 0.6 |
| 8.8 × 10–5 | 3.1 × 10–5 | 1.4 |
aThe considered datasets were measured at a bias voltage of 0.1 V and an electrode speed between 3 and 8 nm s–1. The standard deviations were calculated using the data of two devices for 4, one device for 5 and two devices for 6, respectively.
