Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), name: Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II).
Intramolecular Electron Transfer in Linked Tris(2,2′-bipyridine)ruthenium(II)/Diquat Complexes
Electron transfer (ET) rates have been measured for a series of linked tris(2,2′-bipyridine)ruthenium(II)/diquat complexes in room-temperature acetonitrile solutions, using time-resolved picosecond emission and absorption spectroscopies.The rate of ET from the metal-to-ligand charge transfer (MLCT) states to the diqaut acceptor has been analyzed in terms of a simple kinetic model, in which MLCT exciton hopping is fast, ET to the diquat is rate limiting, and the latter occurs only from MLCT states localized on bipyridine ligands which are linked to diquat acceptors.Electrochemical data for Ru 2+/1+ and Ru 1+/0 reduction potentials have been related to MLCT state energies and used in the model.Semiquantitative agreement was found between the model’s predictions and measured ET times.A linear relationship was found to exist between ET driving force and the log of the ET rate.Reverse (diqaut to ruthenium) ET rates were determined to be fast relative to forward rates.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.name: Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II). In my other articles, you can also check out more blogs about 15746-57-3
