Used in organic light-emitting diodes (OLEDs) as a key intermediate for synthesizing fluorescent dyes and emissive materials. Its structure supports efficient energy transfer and high thermal stability, making it suitable for blue-emitting layers in display technologies. Also employed in research for developing organic semiconductors and photovoltaic devices due to its extended π-conjugation and ability to form charge-transport materials. Commonly used in Suzuki and other palladium-catalyzed coupling reactions to build complex aromatic systems for optoelectronic applications.
