Used as a key intermediate in organic semiconductor materials, particularly in the development of blue-emitting compounds for OLED (organic light-emitting diode) devices. Its rigid, planar structure enhances electron transport and thermal stability, making it suitable for use in thin-film transistors and optoelectronic applications. Also employed in the synthesis of host materials for phosphorescent OLEDs due to its high triplet energy level and good hole-transport properties.
