Molecular elevator, molecular model
Molecular model of a molecular elevator, a type of molecular machine. The elevator is made from small organic molecular subunits. The platformlike component (red) is interlocked with a tripodal riglike component. Switching the pH of the medium around the molecular elevator from acidic (right) to alkaline (left) makes the platform move between two recognition units (blue and yellow) on the tripod. The 2016 Nobel Prize in Chemistry was awarded to the chemists Jean-Pierre Sauvage (b. 1944), Sir J. Fraser Stoddart (b. 1942) and Bernard Feringa (b. 1951) for their work on the design and synthesis of molecular machines. Stoddart's work on molecular elevators was published in 2004.
