Directed, intramolecular electron transfer in mixed-valence dimers

One-electron oxidation of the diners [(dpte)2ClRuII(L)RuIICl(bpy)2] 2+ (dpte = PhSCH2CH2SPh; bpy = 2,2′-bipyridine; L = 4,4′-bipyridine (4,4′-bpy), trans-1,2-bis(4-pyridyl)ethylene (bpe), 1,2-bis(4-pyridyl)ethane (bpa)) gives the corresponding mixed-valence dimers [(dpte)2ClRuII(L)RuIIICl(bpy)2] 3+. In the mixed-valence dimers, Ru(II) → Ru(III) intervalence-transfer (IT) bands are observed. Photolysis into either the π*(bpy) ← dπ(RuIICl(bpy)2) chromophore for the Ru(II)-Ru(II) dimers or the π*(L) ← dπ(RuIICl(dpte)2) chromophore for the mixed-valence dimers results in population of the bpy-based, 3MLCT excited state (-RuIIICl(bpy-·)(bpy)*) as shown by comparisons between room-temperature emission and low-temperature (220-280 K) transient absorption properties of the dimers and the related monomers [(bpy)2ClRu(L)]+. The appearance of the 3MLCT-bpy-based emission in the mixed-valence dimers shows that following π*(L) ← dπ(RuIICl(dpte)2) excitation, ligand to ligand electron transfer, [(dpte)2ClRuIII(L-·)Ru IIICl(bpy)2]3+ → [(dpte)2ClRuIII(L)RuIIICl(bpy -·)(bpy)]3+*, occurs and is competitive with excited-state nonradiative decay by ligand to metal electron transfer, [(dpte)2ClRuII(L)RuIIICl(bpy)2]3+ ← [(dpte)2ClRuIII(L-·)Ru IIICl(bpy)2]3+* → [(dpte)2ClRuIII(L)RuIICl(bpy)2] 3+. Because of the relatively long lifetime of the 3MLCT-bpy state, it is not possible to observe relaxation of the high-energy, mixed-valence isomer to the ground state, [(dpte)2ClRuII(L)RuIIICl(bpy)2] 3+* → [(dpte)2ClRuIII(L)RuIICl(bpy)2] 3+, following nonradiative decay of 3MLCT-bpy. For the pentaammine Ru(II) dimers [(NH3)5RuII(L)RuIICl(bpy) 2]3+ (L = bpe, 4,4′-bpy), excitation into the π*(bpy) ← dπ(RuII) chromophore does not lead to emission or transient decay from the 3MLCT-bpy excited state apparently because of intramolecular energy transfer to lower lying, relatively short-lived (NH3)5RuIII (L-·)-based MLCT states. The 3MLCT-bpy excited state is also not observed following π*(bpy) ← dπ(RuII) excitation in the mixed-valence dimers [(NH3)5RuIII(L)RuIICl(bpy) 2]4+ (L = 4,4′-bpy, bpe) either because of intramolecular quenching by Ru(III) or perhaps because of population of short-lived MLCT states based on the bridging ligand, (NH3)5RuIII(L-·)-.
