Used in organic synthesis as a boronic acid coupling partner in Suzuki-Miyaura cross-coupling reactions to construct biaryl frameworks. Its rigid polycyclic structure makes it valuable for developing organic electronic materials, including semiconductors and luminescent compounds. Commonly employed in the preparation of conjugated polymers and small molecules for OLEDs and organic photovoltaics. Also serves as a building block in medicinal chemistry for designing bioactive molecules with extended aromatic systems.
