Used as a photo-responsive monomer in the synthesis of smart polymers, this compound enables light-triggered changes in material properties. Its azobenzene group undergoes reversible trans-cis isomerization upon UV-Vis light exposure, making it ideal for photo-switchable coatings, optical data storage, and controlled drug delivery systems. Incorporated into polymer networks, it contributes to the development of light-driven actuators and responsive hydrogels. Additionally, it finds use in liquid crystal systems and sensors where external light control is required.
