Used as a multifunctional crosslinking agent in polymer chemistry, particularly in the development of high-performance networks for optoelectronic materials. Its brominated end groups allow for efficient post-functionalization via nucleophilic substitution, enabling the incorporation of fluorescent or electroactive moieties. Commonly employed in the synthesis of aggregation-induced emission (AIE) active frameworks and porous organic networks for sensing applications. Also serves as a precursor in constructing thermally stable dendrimers and star-shaped polymers due to its rigid tetraphenylethene core and four reactive sites.
