Self-assembled monolayers (SAMs) formed by hexabenzocoronene core (HBC) derivatives are incorporated in metal–SAM–metal junctions. Comparisons of the current–voltage curves measured across four junctions show that the HBC units are highly transparent to electrons. HBC SAMs can sustain high bias voltages (higher than 2 V) and are very robust to mechanical stress. These characteristics qualify this material as a promising building block for molecular electronics.
