Used as a key intermediate in organic semiconductor materials, particularly in the development of blue-emitting layers for OLED (organic light-emitting diode) devices. Its rigid aromatic structure and bromine functionalization enable efficient charge transport and facilitate further chemical modifications through cross-coupling reactions. Commonly employed in host materials for phosphorescent OLEDs due to its high triplet energy and thermal stability. Also explored in perovskite solar cells as a hole-transporting material component, enhancing device efficiency and stability.
