Spectrophotometry:Article Title: Synthesis and characterization of the [Ru3O(CH3COO)6(py)2(BPE)Ru(bpy)2Cl](PF6)2 dimer Article Snippet: The polymetallic [Ru3O(CH3COO)6(py)2(BPE)Ru(bpy)2Cl](PF6)2 complex (bpy = 2,2 0-bipyridine, BPE = trans-1,2-bis(4-pyridil)ethylene and py = pyridine) was assembled by the combination of an electroactive [Ru3O] moiety with a [Ru(bpy)2(BPE)Cl] photoactive centre, and its structure was determined using positive ion electrospray (ESI-MS) and tandem mass (ESI-MS/MS) spectrometry.. The [Ru3O(CH3COO)6(py)2(BPE)Ru(bpy)2Cl] 2? doubly charged ion of m/z 732 was mass-selected and subject to 15 eV collision-induced dissociation, leading to a specific dissociation pattern, diagnostic of the complex structure.. The electronic spectra display broad bands at 409, 491 and 692 nm ascribed to the [Ru(bpy)2(BPE)] charge-transfer bands and to the [Ru3O] internal cluster transitions.

UV-vis absorption spectra were obtained using a Article Title: Synthesis, spectroscopy, and electrochemical behavior of a novel supramolecular copper-tetrapyridylporphyrazineruthenium cluster Article Snippet: A novel supramolecular complex displaying extended electronic interactions was obtained by combining the ruthenium cluster [Ru3O(Ac)6(py)2]+ species with the π-conjugated tetrapyridylporphyrazine molecule.. The supramolecular species featured a porphyrazine center attached to four ruthenium clusters and was characterized by electronic and resonance Raman spectroscopy, as well as by cyclic voltammetry and spectroelectrochemistry.. The FTIR spectra were essentially composed of vibrational peaks of the ruthenium cluster species, while the vibrational peaks of the tetrapyridylporphyrazine chromophore dominated the Raman spectra. Article Title: Porphyrin-diones and porphyrin-tetraones: reversible redox units being localized within the porphyrin macrocycle and their effect on tautomerism. Article Snippet: Porphyrin-2,3-diones and porphyrin-2,3,7,8and porphyrin-2,3,12,13-tetraones were shown to have a redox-active unit that can function independently of the macrocycle at large.. Electroreduction of 5,10,15,20-tetrakis(3,5-di-tert-butylphenyl)porphyrin-2,3-diones [(P-dione)M] and the corresponding -2,3,12,13-tetraones [L-(P-tetraone)M] and -2,3,7,8-tetraones [C-(P-tetraone)M], where M ) 2H, CuII, ZnII, NiII, and PdII was investigated and the products were characterized by ESR and thin-layer UV-visible spectroelectrochemistry.. Electrochemical and spectroelectrochemical data show that the first two reductions of the porphyrin-diones and the first three reductions of the porphyrin-tetraones occur at the dione units.
