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 carbazole backbone and brominated phenyl group enhance thermal stability and facilitate further functionalization through cross-coupling reactions. This compound is also employed in the synthesis of host materials for phosphorescent OLEDs, where it helps improve electron transport and device efficiency. Additionally, it finds use in research related to optoelectronic materials due to its favorable triplet energy level and film-forming properties.
