We report the incrementally staged design, synthesis, characterization and operation of a molecular machine that behaves like a nanoscale elevator. The operation of this device, which is made of a platform-like component interlocked with a trifurcated rig-like component and is only 3.5 by 2.5 nanometers in size, relies on the integration of several structural and functional molecular subunits. This molecular elevator is considerably more complex and better organized than previously reported artificial molecular machines. It exhibits a clear-cut on/off reversible behavior and it could develop forces up to around 200 piconewtons.

Abstract
We report the incrementally staged design, synthesis, characterization and operation of a molecular machine that behaves like a nanoscale elevator. The operation of this device, which is made of a platform-like component interlocked with a trifurcated rig-like component and is only 3.5 by 2.5 nanometers in size, relies on the integration of several structural and functional molecular subunits. This molecular elevator is considerably more complex and better organized than previously reported artificial molecular machines. It exhibits a clear-cut on/off reversible behavior and it could develop forces up to around 200 piconewtons.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
