Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of conjugated organic materials. Its spirobifluorene and anthracene moieties provide structural rigidity and thermal stability, making it valuable in the development of organic light-emitting diodes (OLEDs), particularly as a building block for hole-transport or emissive layer materials. The boronate ester group enables efficient carbon-carbon bond formation, allowing incorporation into larger π-conjugated systems for optoelectronic applications. Commonly employed in the fabrication of blue emitters and host materials in OLED displays and lighting devices.
