Control over Rectification in Supramolecular Tunneling Junctions

In complete control: The magnitude of current rectification in well-defined supramolecular tunneling junctions can be controlled by changing the terminal functionality (red spheres) of dendrimers (gray spheres) immobilized on a supramolecular platform (see picture). Junctions containing biferrocene and ferrocene end groups showed larger rectification ratios than junctions containing adamantyl end groups.
