  Absorption, Circular Dichroism, and Luminescence Spectroscopy of Electrogenerated Δ-[Ru(bipy)₃]^+/0/- and Δ-[Os(bipy)₃]^+/0/- (bipy = 2,2‘-Bipyridine)

  摘要：

  The electronic absorption and circular dichroism (CD) spectra of the complexes produced by the one, two, and three electron reduction of Delta-[Ru(bipy)(3)](2+) and Delta-[Os(bipy)(3)](2+) are reported. The CD spectra give unequivocal proof that the added electrons are localized on individual bipiridine ligands and thus that the complexes are correctly formulated [M(bipy)(2)(bipy(-))](+), [M(bipy)(bipy(-))(2)](0), and [M(bipy(-))(3)](-). The absorption spectra of the triply reduced species [M(bipy(-))(3)](-) (M = Ru, Os) are compared to those of the Fe-II and Ir-III analogs. The luminescence spectra of the two triply reduced complexes [Ru(bipy(-))(3)](-) and [Os(bipy(-))(3)](-). are also presented. The MLCT luminescence found in the parent complexes is completely quenched and is replaced by a weak luminescence attributed to the pi(10) --> pi(7) transition of the (coordinated) [bipy](-) ion.

  The electronic absorption and circular dichroism spectra of the complexes produced by the one-, two- and three-electron reduction of DELTA-[os(bipy)3]2+ are reported for the first time. The spectra confirm that, as in the cases of the Fe(II) and Ru(II) analogues, the electrons are localised on the bipyridine ligand and the complexes are correctly formulated [Os(bipy)2(bipy-)]+, [Os(bipy)(bipy-)2]0 and [Os(bipy-)3]-. The absorption spectra of the series of fully reduced complexes [M(bipy-)3]-: M = Fe, Ru, Os are compared.
