Used as an intermediate in organic synthesis, particularly in the preparation of conjugated polymers and small molecule semiconductors for organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its bromine functionality allows for palladium-catalyzed cross-coupling reactions, such as Suzuki or Heck couplings, enabling the construction of complex aromatic systems. The fluorene core provides structural rigidity and enhances electronic properties, making derivatives valuable in optoelectronic materials. Commonly employed in the development of blue-emitting materials in OLED displays and lighting technologies.
