Used in organic synthesis as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds for constructing conjugated organic materials. Commonly employed in the development of organic semiconductors, light-emitting diodes (OLEDs), and conjugated polymers due to its stable boronate ester group and extended π-conjugated fluorene backbone. Its solubility in organic solvents and reactivity with aryl halides make it suitable for synthesizing complex aromatic systems used in electronic and optoelectronic devices.
