Fig. 2: STM-BJ measurement results of NDITTF-MF.

a Schematic of a single-NDITTF-MF molecule junction. b Logarithm-binned 1D histograms for NDITTF-MF measured at an applied bias voltage of 0.5 V. Inset: Sample conductance traces. c Gas-phase HOMO and LUMO orbitals of NDITTF-MF. d 2D conductance-displacement histograms for NDITTF-MF. Inset: Normalized length profiles determined from the 2D histogram. All histograms are compiled from 10,000 traces without data selection.
