Used as a fluorescent probe in biochemical and environmental analyses due to its strong photostability and distinct emission properties. Its structure allows for intercalation into nucleic acids, making it valuable in DNA and RNA detection studies. Also employed in material science for developing organic semiconductors and optoelectronic devices. Serves as a photosensitizer in photodynamic therapy research and in the design of dye-sensitized solar cells. Its electron-accepting nature supports use in redox studies and catalytic systems.
