Used as a fluorescent probe in chemical and biological sensing due to its strong emission properties. Its structure allows for high sensitivity to environmental changes, making it suitable for detecting metal ions and pH variations. Also employed in the development of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) for applications in luminescent sensors, optoelectronic devices, gas adsorption, energy storage, and separation. The carboxylic acid groups enable covalent attachment to surfaces or polymers, enhancing its utility in solid-state sensor systems and organic electronics such as transistors. Shows potential in bioimaging because of its photostability and visible light emission.
