摘要
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.
