Used primarily as a functional monomer in the synthesis of stimuli-responsive polymers, especially those designed for smart materials and optical applications. Its azobenzene moiety enables photo-switching behavior, allowing the polymer to change conformation under light exposure, which is exploited in optical data storage, photoresponsive coatings, molecular switches, and light-triggered drug delivery systems. The methacrylate group facilitates free radical polymerization, enabling incorporation into polymer chains, while the hexyl spacer enhances solubility and reduces steric hindrance, improving responsiveness. Also investigated for use in liquid crystalline polymers, sensors where reversible photoisomerization is required, and photo-controlled displays.
