Used as a key intermediate in organic light-emitting diodes (OLEDs), particularly in blue-emitting materials due to its high triplet energy and good thermal stability. Commonly employed in the electron-transport layer or as a host material in phosphorescent OLEDs. Its bromine functionality allows for easy functionalization via cross-coupling reactions, making it valuable in synthesizing more complex emissive or charge-transport molecules. Also explored in perovskite solar cells as a component in hole-transport materials. Shows promise in optoelectronic devices requiring efficient charge injection and stability.
