Used as a key intermediate in organic semiconductor materials, particularly in the development of blue-emitting layers for OLED (organic light-emitting diode) devices. Its rigid, planar structure enhances charge transport and improves device efficiency. Commonly employed in host materials for phosphorescent OLEDs due to high triplet energy and thermal stability. Also explored in perovskite solar cells as a hole-transporting component. Its derivatization supports tuning of electronic properties for use in optoelectronic applications.
