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), especially as a building block for hole-transport materials or host compounds in emissive layers. Its biphenyl-carbazole structure enhances thermal stability and facilitates efficient charge transport, making it valuable in high-performance optoelectronic devices. Also employed in the synthesis of polymers and small molecules for organic photovoltaics (OPVs) and field-effect transistors (OFETs).
