Used as a key intermediate in organic semiconductors, particularly in the production of blue-emitting materials for OLED (organic light-emitting diode) devices. Its rigid molecular structure enhances thermal stability and improves charge transport, making it suitable for use in display technologies and solid-state lighting. Also employed in host materials for phosphorescent OLEDs due to its high triplet energy level. Additionally, it finds application in hole-transport layers, contributing to device efficiency and longevity.
