Used in organic electronics, particularly in the development of organic light-emitting diodes (OLEDs), due to its excellent hole-transport properties and thermal stability. Its rigid, planar structure supports strong π-conjugation, enhancing electroluminescence efficiency. Also investigated as a host material in phosphorescent OLEDs and as a building block for organic semiconductors in thin-film transistors. Shows potential in photovoltaic devices for improved charge transport.
