Used as a key intermediate in the synthesis of organic semiconductors and optoelectronic materials. Its rigid, conjugated structure enhances charge transport properties, making it valuable in the development of organic light-emitting diodes (OLEDs) and organic field-effect transistors (OFETs). The bromine functionality allows for further cross-coupling reactions, enabling the construction of complex conjugated systems. Also employed in the preparation of fluorescent dyes and sensors due to its strong luminescent characteristics and thermal stability.
