The control of geometrical aspects of formation of molecular arrays on nanosurface, through the design of the organic tectons, was studied and polar or apolar arrangements of directional 1D hybrid coordination networks, with sub-nanometer resolution at the solid/liquid interface, by means of scanning tunneling microscopy (STM), was observed. The design of tectons was based on an anthracene core bearing two ethynyl groups equipped with a monodentate (pyridine) and a tridentate (terpyridine) poles. The packing of the free tecton on graphite surfaces studied by STM displays a polycrystalline structure, which consists of various nanometer-wide domains that are stable over several minutes. The tunneling current through the junction is found to be identical for the adjacent rows of molecules or lamellae, supporting a syn-parallel packing, forming polar domains.
