Used as an intermediate in organic semiconductor materials, particularly in the development of hole-transporting layers for OLED (organic light-emitting diode) devices. Its structural properties enhance thermal stability and improve charge carrier mobility, making it suitable for use in blue-emitting OLEDs. Also employed in the synthesis of host materials for phosphorescent OLEDs due to its high triplet energy level. Additionally, it serves as a building block in the preparation of conjugated polymers and small molecules for optoelectronic applications.
