摘要:The present invention relates to a novel ligand for the synthesis of the photosensitizer ruthenium complexes for uses in DSSC, wherein said ligand comprise in their structure benzodifuran moiety bound directly or by a multiple bond with the 2,2'-bipyridine system in positions 4,4' or fluorene system and methods for preparing of said ligand. The subject of the invention is also a new symmetric or asymmetric photosensitizing ruthenium complex for use in DSSC derived from said ligand and methods for preparation of said complex. The resulting complexes have high molar extinction coefficients in the range of visible light and are stable in air environment and after exposure to sunlight, and may be used for the producing of Dye- Sensitized Solar Cells (DSSC). Developed methods are advantageous due to the mild reaction conditions, high repeatability and moderation or high yields.
