Solid-state chemistry: Crystal tennis rackets

J. Michael McBride1

Top

The idea of bendy crystals, especially ones that move rapidly and reversibly in response to light, seems strange. Such materials have now been prepared — but how do they change shape so dramatically without cracking?

Most chemical reactions are accompanied by a change of molecular shape. Impressively, evolution has harnessed this effect to generate mechanical power for biological 'devices', for example, in muscles, where the bending of myosin upon release of adenosine diphosphate is used to drive one fibre past another1.
