Abstract Coordination complexes are widely investigated to be applied in luminescent sensors, light-emitting devices, and solar energy conversion systems, in particular, ruthenium(II) coordination compounds have favorable characteristics to perform these functions, such as wide light absorption in the visible region, having excited states with energy levels and lifetimes adequate to participate of light conversion process besides having its properties modulated by incorporating different ligands to the metallic ruthenium center, being able to change its light absorption and its photoreactivity. Among all the solar energy conversion systems of principal applications are the Dye-Sensitized Solar Cell (DSSCs) in which the ruthenium complexes participate as the dye-sensitizer. In this device, recombination processes that affect directly its performance occur in the semiconductor| sensitizer interface that might be investigated using specially designed compounds. This research proposal is inserted in this context to synthesize ligands and ruthenium(II) coordination compounds aiming to be used in Dye-sensitized Solar Cells by these dyes, correlating the observed performances with recombination process, such as lateral hole recombination.
