A ruthenium(II)-based complex containing a dendritic terthiophene unit attached to a 2,2'-bipyridine ligand is prepared, and tested in a dye-sensitized solar cell. The use of this complex as sensitizer together with a nanocrystalline anatase TiO2 photoanode results in good performance with excellent stability, featuring a maximum photon-to-electron conversion efficiency of ca. 7.4 % in combination with a 3-methoxypropionitrile-based iodine/iodide redox electrolyte.
