Used primarily as an intermediate in the synthesis of advanced organic materials, particularly in the preparation of conjugated polymers for organic electronics such as organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its rigid, planar structure facilitates extended π-conjugation when incorporated into polymer backbones, enhancing charge carrier mobility and electronic stability. Also employed in research settings to develop novel ligands and catalysts due to the reactivity of its bromine sites in cross-coupling reactions like Suzuki and Ullmann couplings. Limited use in commercial applications due to stability and toxicity concerns.
