Abstract
In a study of eight solvents ranging from 10 to 50 in solvent acceptor number, the reduction not potential values for the Os(VI)(TMC)O2(2+)/ Os(V)(TMC)O2+ couples increase (become less negative) over a range of 600 mV as the solvent acceptor number increases. By contrast, the exci ted-state emission spectra are essentially solvent independent. Thus t he excited-state reduction potential for this system, E(Os(VI)/Os(V) = E(Os(VI)/Os(V)) +DELTAG(*Os(VI)/Os(VI), exhibits solvent dependence through the reduction potential for the ground-state couple (E(Os(VI) /Os(V))) and is solvent tunable to a great degree.
