Used as a key intermediate in the synthesis of organic semiconductors and optoelectronic materials. Its rigid, planar structure enhances electron transport properties, making it valuable in the development of organic light-emitting diodes (OLEDs) and organic thin-film transistors (OTFTs). Frequently employed in the design of high-performance host materials for blue phosphorescent OLEDs due to its strong thermal stability and favorable triplet energy level. Also explored in perovskite solar cells as a component of hole-transport materials to improve device efficiency and stability.
