Used as a photosensitizer in photodynamic therapy and organic semiconductor applications due to its strong absorption in the visible region and ability to generate singlet oxygen. Commonly employed in research for light-harvesting systems and artificial photosynthesis. Also utilized in catalysis, particularly in oxidation reactions, and as a fluorescent probe in imaging studies. Its bulky tert-butyl groups enhance solubility in organic solvents, making it suitable for thin-film devices and supramolecular assemblies.
