Used in polymer chemistry as a fluorescent monomer to synthesize functional polymers with light-emitting properties. Its anthracene group enables UV absorption and fluorescence emission, making it valuable in developing optical sensors, fluorescent labeling agents, and smart materials for bioimaging. Commonly employed in copolymerization to introduce photophysical properties into polymer chains. Also applied in the design of stimuli-responsive materials and organic electronics due to its reversible photo-dimerization behavior.
