Used as a functional monomer in polymer chemistry, particularly in surface modification and photoresist materials. Its phthalimide group enables photochemical crosslinking, making it valuable in lithography for microelectronics. The perfluorophenyl ester reacts selectively with amines, allowing conjugation in biofunctional coatings or responsive polymer systems. The triethylene glycol-like spacer provides flexibility and hydrophilicity, enhancing compatibility in hybrid organic-inorganic systems. Commonly applied in creating patterned surfaces, sensors, and specialty coatings where controlled reactivity and stability are required.
