Used as a fluorescent probe in biochemical and materials science applications due to its strong emission properties and photostability. Its tetraphenol structure allows for hydrogen bonding and metal coordination, making it suitable for sensor design, especially in detecting metal ions or small molecules in solution. Also employed in the development of organic semiconductors and optoelectronic devices because of its extended π-conjugated system. Acts as a building block in supramolecular chemistry for constructing functional nanostructures and molecular networks.
