This compound is widely used in photochemistry and materials science due to its strong light absorption and emission properties. It serves as a photosensitizer in dye-sensitized solar cells (DSSCs), enhancing their efficiency by converting sunlight into electricity. Additionally, it is employed in photocatalytic reactions for organic synthesis and environmental remediation, leveraging its ability to generate reactive species under light irradiation. Its luminescent properties also make it valuable in optical sensors and light-emitting devices. In research, it is utilized as a model complex to study electron transfer processes and photophysical behavior in coordination chemistry. Furthermore, ruthenium polypyridyl complexes like this one are investigated for medical applications, such as photodynamic therapy (PDT) for cancer treatment, utilizing light to selectively destroy cancer cells.
