Widely used in organic electronics, this compound serves as a key intermediate in the synthesis of emissive or charge-transport materials for OLED devices. Its structure supports efficient hole transport and enhances device stability. It is frequently employed in Suzuki-Miyaura cross-coupling reactions to build complex conjugated systems for blue-emitting diodes. Due to the presence of the boronate ester group, it enables precise molecular construction in organic semiconductors. It is also utilized in the development of host materials for phosphorescent OLEDs, where high triplet energy and thermal stability are required. Its biphenyl and carbazole moieties contribute to good film-forming properties and morphological stability in thin-film devices.
