Used as a key intermediate in the synthesis of organic semiconductors and optoelectronic materials. Commonly employed in the development of hole-transport materials for OLEDs (organic light-emitting diodes) due to its strong electron-donating properties and thermal stability. Also utilized in the preparation of fluorescent dyes and sensors for detecting specific analytes in solution. Its bromo functional group allows for further cross-coupling reactions, making it valuable in building complex conjugated systems for use in organic photovoltaics and thin-film transistors.
