Used as a catalyst in organic synthesis, particularly in oxidation and C–H activation reactions. Exhibits high thermal stability and selectivity in converting hydrocarbons under mild conditions. Applied in photodynamic therapy research due to its ability to generate singlet oxygen upon light irradiation. Also investigated for use in dye-sensitized solar cells and as a sensor material for detecting gases like nitric oxide. Its extended aromatic system with chlorophenyl groups enhances solubility and electron-withdrawing properties, improving performance in electrochemical applications.
