Used in organic electronics, particularly in the synthesis of conjugated polymers for organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its boronic ester group enables Suzuki-Miyaura cross-coupling reactions, making it a valuable building block for constructing complex aromatic frameworks. The fluorene backbone with a nitrile substituent enhances electron-accepting properties and stabilizes the molecular structure, improving device efficiency and charge transport. Commonly employed in the development of electron-transport materials and host materials in emissive layers of OLEDs.
