Used as an intermediate in organic semiconductor materials, particularly in the development of hole-transport materials for OLEDs (organic light-emitting diodes). Its aromatic structure and bromine functionalization allow for further cross-coupling reactions, enabling the synthesis of extended conjugated systems. Commonly employed in the fabrication of blue-emitting devices due to its high triplet energy and thermal stability. Also utilized in perovskite solar cells as a dopant-free hole-transport layer, improving device efficiency and long-term stability. Its derivatives are explored in optoelectronic applications, including organic photovoltaics and field-effect transistors.
