Used as a key intermediate in organic semiconductor materials, particularly in the development of blue-emitting layers for OLEDs (organic light-emitting diodes). Its bulky tert-butyl groups enhance solubility and film-forming properties, while the bromophenyl moiety allows for further functionalization via cross-coupling reactions like Suzuki or Buchwald-Hartwig. This makes it valuable in creating host materials or dopants for efficient electroluminescent devices. Also employed in perovskite solar cells as a hole-transporting material due to its favorable energy levels and thermal stability.
