Used as a fluorescent probe in biological imaging due to its aggregation-induced emission (AIE) properties. It remains non-emissive in solution but emits strong fluorescence in aggregated states or when bound to cellular structures, making it useful for cell membrane labeling and tracking. Also applied in optoelectronic devices as an emissive component in organic light-emitting diodes (OLEDs). Its high quantum yield and photostability support use in sensors, including detection of volatile organic compounds (VOCs), and solid-state lighting materials.
