• W2016091251 abstract "The physical and photophysical properties of a series of monometallic, [Ru(bpy)2(dmb)]2+, [Ru(bpy)2(BPY)]2+, [Ru(bpy)(Obpy)]2+ and [Ru(bpy)2(Obpy)]2+, and bimetallic, [{Ru(bpy)2}2(BPY)]4+ and [{Ru(bpy)2}2(Obpy)]4+, complexes are examined, where bpy is 2,2‘-bipyridine, dmb is 4,4‘-dimethyl-2,2‘-bipyridine, BPY is 1,2-bis(4-methyl-2,2‘-bipyridin-4‘-yl)ethane, and Obpy is 1,2-bis(2,2‘-bipyridin-6-yl)ethane. The complexes display metal-to-ligand charge transfer transitions in the 450 nm region, intraligand π → π* transitions at energies greater than 300 nm, a reversible oxidation of the ruthenium(II) center in the 1.25−1.40 V vs SSCE region, a series of three reductions associated with each coordinated ligand commencing at −1.3 V and ending at ∼−1.9 V, and emission from a 3MLCT state having energy maxima between 598 and 610 nm. The RuIII/RuII oxidation of the two bimetallic complexes is a single, two one-electron process. Relative to [Ru(bpy)2(BPY)]2+, the RuIII/RuII potential for [Ru(bpy)2(Obpy)]2+ increases from 1.24 to 1.35 V, the room temperature emission lifetime decreases from 740 to 3 ns, and the emission quantum yield decreases from 0.078 to 0.000 23. Similarly, relative to [{Ru(bpy)2}2(BPY)]4+, the RuIII/RuII potential for [{Ru(bpy)2}2(Obpy)]4+ increases from 1.28 to 1.32 V, the room temperature emission lifetime decreases from 770 to 3 ns, and the room temperature emission quantum yield decreases from 0.079 to 0.000 26. Emission lifetimes measured in 4:1 ethanol:methanol were temperature dependent over 90−360 K. In the fluid environment, emission lifetimes display a biexponential energy dependence ranging from 100 to 241 cm-1 for the first energy of activation and 2300−4300 cm-1 for the second one. The smaller energy is attributed to changes in the local matrix of the chromophores and the larger energy of activation to population of a higher energy dd state. Explanations for the variations in physical properties are based on molecular mechanics calculations which reveal that the Ru−N bond distance increases from 2.05 Å (from RuII to bpy and BPY) to 2.08 Å (from RuII to Obpy) and that the metal-to-metal distance increases from ∼7.5 Å for [{Ru(bpy)2}2(Obpy)]4+ to ∼14 Å for [{Ru(bpy)2}2(BPY)]4+." @default.
