Light-switchable Metal-Organic Cages.

The ability to control structure and function of metal-organic cages by external stimuli offers many possibilities. For example, preventing product inhibition in catalysis, releasing a drug at a specific site, or altering material properties. This Highlight Review describes the different strategies that have been developed to make light-responsive metal-organic cages able to undergo a structural change in response to a light stimulus and furthermore, major challenges and future perspectives are discussed.
