Caption: Above, azobenzene is a molecule that can change its shape with light. An azobenzene molecule switches between two forms under the influence of light. In the lower figure: a molecular cage containing the molecules of the photosensitizer azobenzene. The new mechanism is based on a supramolecular approach in which the molecules of azobenzene and the photosensitizer are locked together in a molecular cage. The limited space accessible to the caged molecules allows only the E-form, but not the Z-form of azobenzene, so this molecule is pushed out of the cage. Credit: Jonathan R. Church
