Used as a photosensitizer in photodynamic therapy for cancer treatment due to its ability to generate reactive oxygen species under light irradiation. Its extended conjugated structure enhances absorption in the visible range, improving therapeutic efficiency.

Also employed in sensing applications for metal ion detection, particularly transition metals, because of distinct color and fluorescence changes upon binding.

Serves as a building block in supramolecular chemistry for constructing metal-organic frameworks with catalytic or magnetic properties.

Shows potential in dye-sensitized solar cells as a light-harvesting component owing to strong and broad absorption characteristics.
