Used in organic light-emitting diodes (OLEDs) as a key intermediate for hole-transport materials due to its excellent thermal stability and electron-donating properties. Its boron-containing structure enables efficient Suzuki-Miyaura cross-coupling reactions, making it valuable in synthesizing conjugated polymers and small molecules for blue-emitting OLEDs. Also applied in perovskite solar cells as a component of hole-transport layers, improving device efficiency and stability. Commonly found in research settings for developing high-performance optoelectronic devices.
