Used as a photosensitizer in photodynamic therapy for cancer treatment, where it generates reactive oxygen species upon light exposure to selectively destroy tumor cells.

Also applied in organic electronics as a component in dye-sensitized solar cells and field-effect transistors due to its strong light absorption and charge transport properties.

Serves as a fluorescent probe in biochemical imaging for detecting specific cellular structures or monitoring molecular interactions.

Employed in catalysis, particularly in oxidation reactions, leveraging its metal-coordinating porphyrin structure.

Investigated for use in sensors for gases and biomolecules because of its sensitive optical response to environmental changes.
