The approach includes a metal-organic cage filled with one azobenzene molecule and one light-absorbing antenna molecule, the sensitizer.

To imitate this structure, Dr Yu designed a new liquid-crystal polymer consisting of a long flexible carbon backbone and azobenzene, a chemical compound made up of two hexagonal rings linked together.

Second, azobenzene’s rings are known to line up with each other when visible light is shone on it, a movement that should make the polymer expand a little.
