Used as a fluorescent probe in biological imaging due to its strong emission properties and sensitivity to environmental polarity. It is effective in detecting changes in membrane fluidity and can bind selectively to certain protein structures, making it useful in studying protein aggregation in neurodegenerative diseases. Also employed in optoelectronic devices as an emissive layer component in organic light-emitting diodes (OLEDs) thanks to its thermal stability and efficient luminescence. Its reversible response to pH changes allows application in developing colorimetric and fluorescent sensors for analytical chemistry.
