We present anab initiostudy of the use of carbon-based tips as electrodes in single-molecule junctions. We show that carbon tips can be combined with other carbon nanostructures to form all-carbon molecular junctions with molecules like benzene or C60. Results show that the use of carbon tips can lead to conductive molecular junctions and open new perspectives in all-carbon molecular electronics.

We report on the temperature-dependent transport behaviors of large-area molecular junctions fabricated with poly-(3,4-ethylene-dioxythiophene) stabilized with polystyrene sulphonic acid (PEDOT:PSS) interlayer electrodes and the archetypal benzenethiol molecules. In this study, we investigated two different benzenethiol molecules: 4-methylbenzenethiol (MBT) and 1,4-benzenedithiol (BDT), which have the identical backbone structure but different top end-groups. The charge transport through the molecular junctions was dominated by distinct interfacial contact properties between the PEDOT:PSS electrodes and the component molecules. We also observed that the electrical characteristics of the MBT junctions are influenced by the PEDOT grain size, particularly depending on the annealing temperature.

We report on an experimental analysis of the charge transport properties of single mesitylene (1,3,5-trimethylbenzene) molecular junctions. The electronic conductance and the current–voltage characteristics of mesitylene molecules wired into Au electrodes were measured by a scanning tunnelling microscopy-based break-junction method at room temperature in a liquid environment. We found the molecular junctions exhibited two distinct conductance states with high conductance values of ca. 10−1 G 0 and of more than 10−3 G 0 (G 0 = 2e 2/h) in the electronic conductance measurements. We further performed a statistical analysis of the current–voltage characteristics of the molecular junctions in the two states. Within a single channel resonant tunnelling model, we obtained electronic couplings in the molecular junctions by fitting the current–voltage characteristics to the single channel model. The origin of the high conductance was attributed to experimentally obtained large electronic couplings of the direct π-bonded molecular junctions (ca. 0.15 eV). Based on analysis of the stretch length of the molecular junctions and the large electronic couplings obtained from the I–V analysis, we proposed two structural models, in which (i) mesitylene binds to the Au electrode perpendicular to the charge transport direction and (ii) mesitylene has tilted from the perpendicular orientation.
