title: Synthesis of Amphiphilic Ru(II) Heteroleptic Complexes Based on Benzo[1,2-b:4,5-b']dithiophene: Relevance of the Half-Sandwich Complex Intermediate and Solvent Compatibility.
abstract: The detailed synthesis and characterization of four ruthenium(II) complexes [RuLL'(NCS)2 ] is reported, in which L represents a 2,2'-bipyridine ligand functionalized at the 4,4' positions with benzo[1,2-b:4,5-b']dithiophene derivatives (BDT) and L' is 2,2'-bipyridine-4,4'-dicarboxylic acid unit (dcbpy) (NCS=isothiocyanate). The reaction conditions were adapted and optimized for the preparation of these amphiphilic complexes with a strong lipophilic character. The photovoltaic performances of these complexes were tested in TiO2 dye-sensitized solar cell (DSSC) achieving efficiencies in the range of 3-4.5 % under simulated one sun illumination (AM1.5G).
