Used extensively in photochemical applications, particularly in dye-sensitized solar cells (DSSCs), where it acts as a photosensitizer. Its ability to absorb light efficiently and transfer electrons makes it a key component in improving the energy conversion efficiency of these cells. Additionally, it is employed in photocatalytic reactions, aiding in the breakdown of organic pollutants under light exposure. In research, it serves as a model compound for studying electron transfer processes and photophysical properties in coordination chemistry. Its stability and photoresponsive characteristics also make it suitable for use in light-emitting devices and sensors.
