Used as a fluorescent probe in biological imaging due to its strong emission properties and ability to bind selectively to cellular components. Its structure allows for good cell membrane permeability, making it suitable for live-cell imaging. Also employed in the development of organic light-emitting diodes (OLEDs) as a component in emissive layers for its efficient luminescence. Additionally, serves as an intermediate in synthesizing more complex dyes and photoactive compounds for use in sensors and optoelectronic devices.
