Used in polymer chemistry as a crosslinking monomer to introduce photo-responsive or stimuli-responsive properties into polymer chains. The acrylate group allows for easy incorporation into acrylic-based copolymers via free radical polymerization, while the protected hydroxyl functionality (Boc-protected phenol) can be deprotected under mild acidic conditions to release a phenolic hydroxyl group. This enables post-polymerization modification or facilitates interactions such as hydrogen bonding, chelation, or further functionalization in coatings, adhesives, or smart materials. Commonly applied in the development of functional thin films, photoresists, and stimuli-responsive hydrogels where controlled release or environmental sensitivity is required.
