Used as a key intermediate in the synthesis of organic electronic materials, particularly in the development of conjugated polymers and small molecules for organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its boronic ester functionality enables efficient cross-coupling reactions, such as Suzuki-Miyaura coupling, to construct complex π-conjugated systems. Additionally, it finds application in the preparation of fluorescent probes and sensors due to its electron-rich diethylamino group, which enhances optical properties. The compound is also employed in research focused on designing advanced materials for optoelectronic devices.
