The two‐dimensional ordering of a number of 2,2′‐bipyridine derivatives at the liquid/solid interface has been investigated by scanning tunneling microscopy. By appropriate functionalization of the bipyridine units, their intermolecular distance can be tuned, which has proved to be crucial for complexation with metal ions. The in situ addition of metal salts (Pd 2+ , Cu 2+ ), leading to the formation of metal‐bipyridine complexes, has a dramatic influence on the two‐dimensional ordering of the molecules and suggests that these complexes could be used as templates.
