Used in organic electronic devices as a fluorescent dye or sensitizer due to its strong light absorption and emission properties. Commonly applied in the development of optical sensors and imaging agents, especially in research settings where precise detection of specific analytes is required. Its structure allows for modification to tune photophysical behavior, making it suitable for use in dye-sensitized solar cells and fluorescence-based bioassays. Also explored in photopolymerization initiators and as a component in advanced material synthesis for optoelectronic applications.
