Used as a catalyst in organic synthesis, particularly in oxidation reactions. It promotes the selective oxidation of hydrocarbons and alcohols under mild conditions. Also applied in electrochemical systems due to its redox activity, serving as a mediator in sensors and fuel cells. Shows potential in photodynamic therapy and as a photosensitizer in light-driven processes. Its stability and tunable electronic properties make it suitable for use in thin-film devices and conductive materials.
