Molecular junctions generally consist of three main components: a molecular bridge , metal electrodes , and terminal anchor groups that electronically couple the bridge to the electrodes . Terminal anchors play a key role in controlling the electronic properties of single molecule junctions via molecular binding, junction stability, and electronic coupling. One class of robust terminal anchors is characterized by dative bonding interactions with metal electrodes, including amine , thiol , pyridine , and methyl thiol groups. However, molecular junctions generally require two terminal anchor groups to form a closed circuit, which poses synthetic challenges that tend to restrict the chemical space for molecular junction design. From this view, new binding modalities that avoid the requirement of two terminal anchors could expand the scope of the chemical toolbox available for molecular electronics.
