investigation of the effects of the coupling between dissimilar ligands in the excitedstates of the complexes [Ru(bipy)n(phen)3–n]2+, [Ru(bipy)n(4,7-Ph2phen)3–n]2+ and [Ru(bipy)n(5-NO2phen)3–n]2+(n= 0, 1, 2 or 3)(bipy = 2,2′-bipyridine, phen = 1,10-phenanthroline) is presented. Proton magnetic resonance measurements upon the ground states of the complexes [Ru(bipy)n(phen)3–n]2+ show that the chemical shifts

Electronic absorption spectra in the wavelength range 200–800 nm are reported for the series of complexes RuL32+ and RuL2L′2+ with L and L′ being various bipyridyl-type ligands, and for the series of reduction products of these complexes corresponding to species with +1, 0 and −1 overall charges. These species were studied as non-aqueous solutions in a cell fitted with an optically transparent thin
的波长范围内的电子吸收光谱200-800纳米被报告为系列络合物RUL的3 2+和RUL 2 'L 2 +与L和L'是各个联吡啶基型配体,以及用于该系列的这些还原产物对应于总电荷为+1、0和-1的物种的复合物。在装有光学透明薄层电极(OTTLE)的电池中,将这些物质作为非水溶液进行了研究,在该电极上可观察到可控的逐步降低。在适当的情况下,已经根据局部电子模型解释了伴随的光谱变化,其中涉及配位配体的自由基阴离子形式的鉴定。
Photoinduced Electron-Transfer Reactions: A Study of the Diffusion-Controlled and Activation-Diffusion-Controlled Processes
the rate constants of the reaction [IrCl6]2−+ [Ru(bpy)3]2+* in these NaNO3 solutions. The rate constants of this reaction were also obtained by fluorescence quenching measurements. The agreement between the two sets of data (experimental and predicted) is excellent. The trends of association (kd) and dissociation (k−d) rate constants for 2+/3−, 2+/2−, and 2+/2+ reactions in NaNO3 solutions are discussed
