Used in organic light-emitting diodes (OLEDs) as a key component in emissive and host layers due to its good thermal stability and hole-transport properties. Its bromine functionality allows for further chemical modification through cross-coupling reactions, making it a valuable intermediate in the synthesis of larger conjugated systems for optoelectronic devices. Also employed in the development of organic semiconductors and phosphorescent materials for display technologies and solid-state lighting. Shows potential in photovoltaic cells as a dopant or charge-transport material.
