A molecule that switches on and off

Researchers in France have developed a single molecule whose charge state and shape can be changed at will. The advance should prove a key advantage in the race for miniaturization. In addition to controlling its charge in a completely reversible way, the researchers have revealed a link between the molecule’s charge and its geometrical shape, effectively making it usable as a bit of information or an electromechanical system on a nanometric scale. This perfectly controllable back-and-forth motion at the molecular level holds great promise for the creation of ultra-dense digital memory or nanomotors.
