Cover Picture: Spectroscopic Tracking of Molecular Transport Junctions Generated by Using Click Chemistry (Angew. Chem. Int. Ed. 28/2009)

The in situ generation of molecules that bridge nanogaps generated by on‐wire lithography is achieved by using click chemistry. C. A. Mirkin, M. A. Ratner, and co‐workers show in their Communication on page 5178 ff. that these molecular junctions give high yields, and they describe how this strategy can be generalized to incorporate diverse molecular architectures within the nanogaps. Tracking of the molecular assembly process within the nanogaps is allowed by their strong electromagnetic field.
