Used as an intermediate in organic synthesis, particularly in the development of advanced optoelectronic materials. It serves as a building block for creating light-emitting compounds in OLEDs (organic light-emitting diodes) due to its rigid, conjugated structure that supports efficient electron transport and luminescence. The presence of bromine allows for further functionalization via cross-coupling reactions, enabling tailored modifications for use in semiconductor materials and photovoltaic devices. Also employed in the synthesis of specialty resins and polymers with enhanced thermal and oxidative stability.
