Fig. 7: Light responsive structural color actuators based on azobenzene-containing CLC networks.

a Molecular structures of the monomers used to prepare the CLC networks. b Actuation at 25 °C (below Tg): reflection spectra and photographs of the CLC film with 405 nm light irradiation (right), and after 532 nm light irradiation (left). c Actuation at 50 °C (above Tg): the CLC film exhibited a redshift of the structural color and bending upon 405 nm light irradiation at 50 °C.
