Used as a fluorescent probe in biochemical and analytical applications due to its strong emission properties upon binding to specific biomolecules. It is particularly effective in detecting conformational changes in proteins and nucleic acids. The compound’s rigid structure and extended π-conjugation enhance sensitivity in cellular imaging, making it suitable for live-cell microscopy. Also employed in the development of chemosensors for metal ions, where fluorescence response changes selectively in the presence of cations like zinc or copper. Its two-photon absorption characteristics allow deep-tissue imaging with reduced background interference. Additionally, it serves as a building block in supramolecular chemistry for designing photoresponsive materials.
