Notes:
Direct measurements of dynamic charge localization in tris (2,2′-bipyridyl) ruthenium (II) have been performed in fluid solution for the first time. Using picosecond Raman spectroscopy it has been determined that charge localization occurs on a time scale of (very-much-less-than)30 ps for low-viscosity solvents. In high-viscosity solvents such as glycerol at room temperature, the charge localized species Ru(bpy)2(bpy)− appears on a time scale of 100 ps. It is clear from these data that solvent reorganization is one of the dominant mechanisms in electron trapping.
