Used as an intermediate in the synthesis of organic semiconductors and optoelectronic materials. Commonly employed in the production of OLEDs (organic light-emitting diodes) due to its ability to form stable hole-transport materials and emissive layers. Also utilized in the development of organic photovoltaics (OPVs) and perovskite solar cells as a building block for hole-transporting compounds. Its bromine functionality allows for easy modification via cross-coupling reactions, making it valuable in creating complex conjugated systems for advanced electronic devices.
