To grow one-dimensional metallic wires in atomic scale is an extremely charming and challenging target in nanotechnology, e.g. controllable electronic circuits and nanodevices. A possible solution is to build up one-dimensional molecular moulding chains to trap metal atoms beneath, as the schematic in figure (a). Two Lander molecules (A and B) with tert-butyl lifting legs are designed as the candidates, which are expected to create such a molecular tunnel by alternating A-B-A-B molecules via triple complementary hydrogen bonding between the diamino-pyridine and diimide functional groups, shown in figure (b). Using variable-temperature scanning tunnelling microscopy (STM), the conformation of the molecular chain is characterised in UHV. By removing some of molecules of the molecular chain via STM manipulation, the structure of metallic wires moulded under the molecular chain are proved.
