Used as a fluorescent probe in biological imaging due to its aggregation-induced emission (AIE) properties. It emits strong light in aggregated states, making it suitable for tracking cellular processes without causing significant background interference. Applied in monitoring cell membrane dynamics and protein interactions. Also utilized in the development of chemosensors for detecting metal ions and pH changes in aqueous environments. Its carboxylic acid group allows for easy conjugation to biomolecules, enhancing targeting specificity in diagnostic applications. Additionally, employed in solid-state optoelectronic devices where stable luminescence is required.
