Ruthenium polypyridyl compounds have chemical, electrochemical and photophysical properties recognized to be used in a wide variety of devices such as luminescent sensors, photoinduced devices and Dye-sensitized Solar Cells (DSSCs). Another device capable of directly convert sunlight into electricity are the organic solar cells and among its components, the use of poly-fullerenes have been gaining attention as the hole-transfer layer. These polymers are formed by the chemical reaction of formyl groups and fullerenes. This project aims to synthesize the 4,4'-diformil-2,2'-bipyridyl ligand and subsequently its coordination to ruthenium(II). It will by prepared homoleptic ruthenium(II) compounds using this ligand and heteroleptic compounds using, besides the synthesized ligand, other compounds such as the 4,4'-dicarboxy-2,2'-bipyridyl and the thiocyanate anion. By this way, we intend to obtain coordination compounds that are able to be used in the preparation of poly-fullerenes aiming that this new material can have the intrinsic advantages of the coordination compound that constitute itself.
