Used as a fluorescent sensor material in optoelectronic devices due to its strong blue emission and high thermal stability. Commonly applied in organic light-emitting diodes (OLEDs) as an emissive layer component. Also employed in chemical sensing for detecting volatile organic compounds and metal ions because of its fluorescence quenching properties. Its rigid structure enhances charge carrier mobility, making it suitable for organic field-effect transistors (OFETs). Additionally, it serves as a host matrix in phosphorescent OLEDs to improve device efficiency and lifetime.
