Information storage flips molecules out : The orientation of individual molecules—vertically or horizontally on a Cu(111) surface—can be controlled in an electrolyte solution by application of an electrode potential. The transition is completely potential dependent, reversible and stable; such are the minimum requirements for computer memory devices. STM images show two orientations of an adlayer of 2,2′‐bipyridine (see graphic).
