Design of a synergistic photoactuator. Schematic drawing of a photochemical and b photothermal actuation. c Chemical composition of the liquid crystal monomer mixture. d, UV–Vis spectra of LCN film containing both DB14 and azobenzene crosslinks. The arrows indicate the excitation wavelengths used in the actuation: 365 nm for trans–cis isomerization (purple arrow), 460 nm for cis–trans isomerization (blue arrow), and 660 nm for photothermal heating (red arrow). e Cis-lifetime during the thermal relaxation in the dark (cis–trans) and time to reach photostationary state upon UV irradiation (trans–cis) at different temperatures
