Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of conjugated organic materials. It plays an important role in the development of organic semiconductors, particularly in creating hole-transport materials for organic light-emitting diodes (OLEDs) and perovskite solar cells. The presence of bromoaryl groups and a boronate ester allows for selective and efficient biaryl bond formation, enabling the construction of complex triarylamine-based architectures. These structures are valued for their thermal stability and excellent charge-transport properties in electronic devices.
