Used as a monomer in polymer chemistry, particularly in the synthesis of functional polymers with aromatic and halogenated structures. Its vinyl ether group enables cationic polymerization, allowing the formation of linear or cross-linked materials with unique thermal and optical properties. The presence of iodine facilitates post-polymerization modifications through coupling reactions, such as Heck or Suzuki reactions, enabling the introduction of conjugated systems for applications in organic electronics, sensors, and advanced coatings. Also employed as a building block in the preparation of liquid crystals and photoresponsive materials due to its ability to undergo controlled photochemical transformations.
