Used as a key building block in organic electronics, particularly in the development of organic light-emitting diodes (OLEDs). Its rigid aromatic structure provides excellent thermal and oxidative stability, making it ideal for use in hole-transport materials and host compounds in blue-emitting OLED devices. Also employed in perovskite solar cells as a dopant-free hole-transport layer to improve device efficiency and stability. Additionally, it serves as a structural motif in pharmaceuticals and agrochemicals due to its ability to interact with biological targets through π-π stacking and hydrophobic interactions.
