COVER Spatial control over molecular movement is typically limited because motion at the atomic scale follows stochastic processes. When single dibromoterfluorene molecules are aligned along a specific direction on a silver surface, they become highly mobile and can be controllably transferred between two sharp probes, as illustrated here. Such a sender-receiver experiment enables transport of information, encoded in individual molecular entities, between precisely defined locations. See pages 912 and 957.
