Used in photodynamic therapy as a photosensitizer due to its ability to generate singlet oxygen upon light irradiation. It is also employed in organic semiconductors and dye-sensitized solar cells for its excellent light absorption and electron transfer properties. Its brominated structure allows for further functionalization in synthetic chemistry, making it useful in the development of catalysts and molecular sensors. Additionally, it serves as a building block in porphyrin-based metal-organic frameworks (MOFs) for catalytic and sensing applications.
