Specific solvent effects of hydroxylic solvents on the emission properties of ruthenium(ii)tris(2,2'-bipyridyl) chloride.
The excited state of Ru(II)[bpy]3 (2+) dissolved in hydroxylic solvents is subject to specific solvent effects, which were hitherto not understood on a quantitative basis. We determined the solvent effects of linear monovalent alcohols on the energy gap law of internal conversion with the help of lifetime and intensity measurements. An on-line method for measurement of the temperature dependence of quantum efficiencies was introduced. A modified Franck-Condon analysis of emission spectra by taking into account the shape of a Morse potential of the involved states was applied to compute excited-state energies.
