Used in organic electronics due to its strong electron-donating properties and high thermal stability. Commonly applied in organic light-emitting diodes (OLEDs) as a hole-transport material or emissive layer component. Also investigated for use in organic photovoltaics (OPVs) and field-effect transistors (OFETs) because of its excellent charge-carrier mobility and planar molecular structure that promotes π-π stacking. Its rigid fused-ring system enhances luminescence efficiency, making it suitable for blue-emitting devices. Additionally explored in fluorescent sensors and bioimaging due to its intrinsic fluorescence and ability to interact with biological molecules.
