Azobenzene is widely used in the field of photoresponsive materials due to its ability to undergo reversible trans-cis isomerization when exposed to light. This property makes it valuable in the development of light-controlled molecular switches, which are applied in data storage devices, optical sensors, and smart coatings. In the textile industry, azobenzene derivatives are incorporated into fabrics to create light-responsive materials that change color or properties under UV light. Additionally, it plays a role in drug delivery systems, where light-triggered release of therapeutic agents is achieved using azobenzene-based compounds. Its applications also extend to liquid crystal displays (LCDs), where it helps in modulating light transmission and improving display performance.
