Abstract
Laser flash photolysis of aqueous solutions of tris(2,2 ′-bipyridyl) ruthenium(II) cation (Ru(bpy) 3 2+, bpy=2,2 ′-bipyridyl) induced transient absorbance changes in the near-IR region. The transient absorption with a peak at around 900 nm was assigned as a triplet–triplet transition of the metal-to-ligand charge transfer (MLCT) excited state of Ru(bpy) 3 2+. The quantum efficiency for the MLCT state formation ( φ) and the molar absorption coefficient at 900 nm ( ϵ *) were determined to be φ=1.00±0.04 and ϵ *=1420±30 M −1 cm −1, respectively, by applying the method of intensity dependence measurement.
