Figure 4: Photochemical and photothermal material responses.

(a) UV-vis spectra of azo-LCN films with light (320–500 nm) irradiation at 200 mW cm⁻² intensity. (b) Summary of ultraviolet–vis absorbance (at 365 nm) of azo-LCN films subjected to 30 mW cm⁻² (Empty circle) and 200 mW cm⁻² (Red filled circle) light intensities. (c) Thermal image and temperature evolution for azo-LCN films on exposure to the light intensities of 30 mW cm⁻² (Purple color diamond), 100 mW cm⁻² (Black filled circle), 200 mW cm⁻² (Red filled square), 300 mW cm⁻² (Blue color traingle) and 500 mW cm⁻² (Green color inverted traingle).
