Molecular devices made via the manipulation of single molecules in scanning probe microscopes have usually been assembled at cryogenic temperatures. Only few related manipulation experiments have been demonstrated at ambient temperature, at which application of the molecular devices are more easily conceivable. Here, we present room-temperature intermolecular signal transfer and processing using SnCl2Pc molecules on a Cu(100) surface. The in-plane orientations of molecules, which were used as information carrier, were effectively coupled through a series of controlled manipulations. The resulting arrays of coupled molecules realize different functions including logical gates, a motor, and a signal transfer circuit. The results highlight a strategy for building functional molecular devices at room temperature.
