Development of the ruthenium-based photosensitizer
Ruthenium complexes are categorized as one of the best dyes(s) that can absorb light energy efficiently when it binds to Titanium (IV) Dioxide, and this combination is used for the water splitting process. Our present study is to make a ruthenium complex that contains a dipyrazolylpyridine ligand, which will be used as a better catalyst for water splitting. A series of ruthenium(II) complexes has been synthesized and obtained as air-stable dark maroon solids. These ruthenium complexes are characterized by NMR, Single Crystal X-Ray diffraction, and ESI MS studies.
Designed, developed, characterized, and studied the photophysical properties of the novel Ruthenium complexes for the application in water-splitting reactions and dye-sensitized solar cells (DSSCs) using NMR, XRD single-crystal, UV-Vis, Fluorescence, and ESI-MS spectroscopy.
