Used as a key intermediate in the synthesis of conjugated organic semiconductors, particularly in the development of high-performance organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its rigid aromatic structure and strong electron-withdrawing nature enhance charge carrier mobility and stability in thin-film devices. Also employed in the preparation of functional dyes and fluorescent probes due to its ability to participate in π-conjugated systems with tunable optical properties. Commonly utilized in cross-coupling reactions to build complex heterocyclic frameworks for optoelectronic materials.
