Used as a key intermediate in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions for the construction of complex conjugated systems. It plays an important role in the development of organic electronic materials, including hole-transport materials and emitters in organic light-emitting diodes (OLEDs). Its structural framework supports high triplet energy and good thermal stability, making it suitable for applications in phosphorescent and thermally activated delayed fluorescence (TADF) devices. Also employed in the design of photoredox catalysts and dye-sensitized solar cells due to its strong electron-donating properties and tunable redox behavior.
