Synthetic Route of 37366-09-9, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2. In a patent, introducing its new discovery.
Strategies for optimizing the performance of cyclometalated ruthenium sensitizers for dye-sensitized solar cells
Pursuant to our goal of optimizing the performance of cyclometalated Ru sensitizers in the dye-sensitized solar cell (DSSC), the physicochemical properties of a series of tris-heteroleptic RuII complexes are reported. Each of these complexes contains a metal ligated by: (i) a bidentate 2,2?-bipyridine-4,4?-dicarboxylic acid (dcbpy) ligand to anchor the dye to the TiO2 surface; (ii) a cyclometalating ligand – withelectron-withdrawing groups to ensure a sufficiently high oxidation potential for dye regeneration in the DSSC; and (iii) a 2,2?-bipyridine (bpy) ligand. UV/Vis and electrochemical data reveal that each complex exhibits broad metal-to-ligand charge transfer (MLCT) bands of significant intensity (Imu = 1.0-2.3 A – 104 M-1 cm-1) in the visible region, and ground- and excited-state redox potentials that are appropriate for sensitizing TiO2. Analysis of the dyes in the DSSC highlights the sensitivity of cell performance to the oxidation potential for each of the dyes, which has important implications in the development of cyclometalated Ru sensitizers.
