Used as a key intermediate in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions for the preparation of conjugated organic materials. Commonly applied in the development of organic light-emitting diodes (OLEDs), serving as a building block for hole-transport materials and host compounds in emissive layers. Its biphenyl and carbazole moieties contribute to high thermal stability and efficient charge transport, making it suitable for use in blue-emitting OLED devices. Also employed in the synthesis of organic semiconductors and photovoltaic materials due to its favorable electronic properties and ability to form stable radical species.
