Application of 15746-57-3, 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.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a patent, introducing its new discovery.
Interfacial energy conversion in RuII polypyridyl-derivatized oligoproline assemblies on TiO2
Solid-phase peptide synthesis has been applied to the preparation of phosphonate-derivatized oligoproline assemblies containing two different Ru II polypyridyl chromophores coupled via “click” chemistry. In water or methanol the assembly adopts the polyproline II (PPII) helical structure, which brings the chromophores into close contact. Excitation of the assembly on ZrO2 at the outer RuII in 0.1 M HClO 4 at 25 C is followed by rapid, efficient intra-assembly energy transfer to the inner RuII (kEnT = 3.0 ¡Á 10 7 s-1, implying 96% relative efficiency). The comparable energy transfer rate constants in solution and on nanocrystalline ZrO 2 suggest that the PPII structure is retained when bound to ZrO 2. On nanocrystalline films of TiO2, excitation at the inner RuII is followed by rapid, efficient injection into TiO 2. Excitation of the outer RuII is followed by rapid intra-assembly energy transfer and then by electron injection. The oligoproline/click chemistry approach holds great promise for the preparation of interfacial assemblies for energy conversion based on a family of assemblies having controlled compositions and distances between key functional groups.
