Used as a key intermediate in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions for the preparation of conjugated organic materials. It plays an important role 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-carbazole structure provides good thermal stability and efficient charge transport, making it suitable for high-performance optoelectronic devices. Also employed in the synthesis of polymers and small molecules for organic photovoltaics (OPVs) and field-effect transistors (OFETs).
