Used as a fluorescent probe in biochemical and analytical applications due to its strong emission properties upon binding to metal ions or changes in pH. Its structure allows for chelation with transition metals, making it useful in sensors for detecting metal ions in environmental and biological samples. Also employed in the development of organic semiconductors and optoelectronic devices because of its extended π-conjugation system. Shows potential in photodynamic therapy research as a photosensitizer that generates reactive oxygen species under light irradiation.
