Structure, spectroscopy and electrochemistry of the bis(2,2?-bipyridine)(salicylato)ruthenium(II) complex

The bis(2,2?-bipyridine)(salicylato)ruthenium(II) complex has been prepared and characterized by means of single crystal X-ray diffraction, electrochemistry and resonance Raman spectroscopy. The electronic bands in the visible region have been assigned to Ru-bipy charge-transfer transitions and discussed in terms of ZINDO/S semiempirical calculations. Spectroelectrochemical measurements have been performed in order to elucidate the nature of the electrochemical waves in the cyclic voltammograms. The green complex generated by oxidation of the complex at 0.25 V has been isolated, revealing substantial ruthenium-salicylate electronic mixing, as deduced from the corresponding resonance Raman spectra. Further oxidations at 1.2 and 1.4 V have been observed and ascribed to hydroxylation of the salicylate semiquinone ligand in the complex.

Synthesis, photophysical, and electrochemical properties of two novel trinuclear Ru(II) polypyridyl complexes

Two polypyridyl ligands 2,2?,2?-tris((4,5-diazafluoren-9-yliminoxy)ethyl)amine (L1) and 1,3,5-tris((4,5-diazafluoren-9-yliminoxy)methyl))-2,4,6-trimethylbenzene (L2), and corresponding trinuclear Ru(II) complexes [(bpy)6L1-2(RuII)3](PF6)6 (Ru-L1, Ru-L2) have been synthesized. Cyclic voltammetry of the complexes are consistent with one Ru(II)-centered oxidation at 1.32 V and four ligand-centered reductions. Photophysical behaviors are investigated by UV-Vis absorption and fluorescence spectrometry. The two complexes show metal-to-ligand charge transfer absorption at 440 nm and emission at around 580 nm.

Catalytic alkene epoxidation with ruthenium complexes and hydrogen peroxide

Bis(bipyridyl)dichlororuthenium(II) has been shown to catalyse the stereospecific epoxidation of oleic acid. The reaction occurs at ambient temperatures using hydrogen peroxide oxidant and in water-miscible oxidation resistant solvents. The rate has been shown to be first order in hydrogen peroxide and catalyst, and negative first order with respect to the substrate.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of: Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), you can also check out more blogs about15746-57-3

Automated synthesis of 3?-metalated oligonucleotides

We report the first synthesis ofa metallonucleoside bound to a solid support and subsequent oligonucleotide synthesis with this precursor. Large-scale syntheses of metal-containing oligonucleotides are achieved using a solid support modified with [Ru(bpy)2(impy?)]2+ (bpy is 2,2?-bipyridine; impy? is 2?-iminomethylpyridyl-2?-deoxyuridine). A duplex formed with the metal-containing oligonucleotide exhibits superior thermal stability when compared to the corresponding unmetalated duplex (Tm = 50 C vs Tm = 48 C). Electrochemical (E1/2 = 1.3 V vs NHE), absorption (lambdamax = 480 nm), and emission (lambdamax = 720 nm, tau = 44 ns, Phi = 0.11 ¡Á l0-3) data for the ruthenium-modified oligonucleotides indicate that the presence of the oligonucleotide does not perturb the electronic properties of the ruthenium complex. The absence of any change in the emission properties upon duplex formation suggests that the [Ru(bpy)2(impy)]2+ chromophore will be a valuable probe for DNA-mediated electron-transfer studies. Despite the relatively high Ru(III/II) reduction potential, oxidative quenching of photoexcited [Ru(bpy)2(impy)]2+ does not lead to oxidative damage of guanine or other DNA bases.

Oximated ruthenium tris-bipyridyl complex: Synthesis and luminescent response specifically for ClO- in water containing multiple ions

Hypochlorite has been widely and essentially used as the disinfecting agent of water in our daily life. Rapidly, specifically, quantitatively and simply monitoring ClO- in water remains to be investigated and is of importance. For this purpose a novel complex bis(2,2?-bipyridine)(4?-methyl-2,2?-bipyridyl-4-carbaldehyde oxime)ruthenium chloride (Ru-CN-OH) was prepared. In water, reaction of complex Ru-CN-OH and ClO- results in bis(2,2?-bipyridine)(4?-methyl-2,2?-bipyridyl-4-carboxylic acid)ruthenium (Ru-CO2H) and thereby offers an efficient luminescence response. This was ascertained to be a specific oxidation reaction of complex Ru-CN-OH with ClO-, and can be used for quantitatively monitoring aqueous ClO-. The product of the oxidation reaction of complex Ru-CN-OH and ClO- was isolated and assigned to Ru-CO2H. The luminescent emission spectra of complex Ru-CN-OH in the presence of ClO- demonstrated that the coexistence of F-, Cl-, Br-, I-, HCO3-, HSO4-, H2PO4-, S2O32-, SO32-, CO32-, PO43-, HPO42-, NO3-, AcO-, Li+, Na+, K+, Ca2+, Mg2+, Zn2+, Co2+, Fe3+, Ni2+, Pb2+, Hg2+, Mn2+ and Cu2+ did not interfere in the quantitative change of the intensity of the luminescent emission.

Photonic wires of nanometric dimensions. Electronic energy transfer in rigid rodlike Ru(bpy)32+-(ph)n-Os(bpy)3 2+ compounds (ph = 1,4-phenylene; n = 3, 5, 7)

We have synthesized nine rodlike compounds of nanometric dimension with general formula [M(bpy)3-(ph)n-M?(bpy)3]4+ (M = M? = Ru(II); M = M? = Os(II); M = Ru(II), M? = Os(II); bpy = 2,2?-bipyridine; ph = 1,4-phenylene; n = 3, 5, 7; the central phenylene unit bears two alkyl chains for solubility reasons; the metal-to metal distance is 4.2 nm for the longest spacer). The absorption spectra and the luminescence properties (emission spectra, quantum yields, and excited-state lifetimes) of the nine dinuclear complexes have been investigated in acetonitrile solution at 293 K and in butyronitrile rigid matrix at 77 K. The results obtained have been compared with those found for the separated chromophoric units ([Ru(bpy)3]2+, [Os(bpy)3]2+, and oligophenylene derivatives). The absorption spectrum of each dinuclear complex is essentially equal to the sum of the spectra of the component species, showing that intercomponent electronic interactions are weak. In the homodinuclear compounds, the strong fluorescence of the oligophenylene spacers is completely quenched by energy transfer to the metal-based units, which exhibit their characteristic metal-to-ligand charge-transfer (MLCT) phosphorescence. In the heterodinuclear compounds, besides complete quenching of the fluorescence of the oligophenylene spacers, a quenching of the phosphorescence of the [Ru(bpy)3]2+ chromophoric unit and a parallel sensitization of the phosphorescence of the [Os(bpy)3]2+ chromophoric unit are observed, indicating the occurrence of electronic energy transfer. The rate of the energy-transfer process from the [Ru(bpy)3]2+ to the [Os(bpy)3]2+ unit is practically temperature independent and decreases with increasing length of the oligophenylene spacer (in acetonitrile solution at 293 K, ken = 6.7 ¡Á 108 s-1 for n = 3; ken = 1-0 ¡Á 107 s-1 for n = 5; ken = 1-3 ¡Á 106 s-1 for n = 7). It is shown that such an energy-transfer process takes place via a Dexter-type mechanism (superexchange interaction) with an attenuation coefficient of 0.32 per A and 1.5 per interposed phenylene unit.

Ruthenium(II)-polypyridyl zirconium(IV) metal-organic frameworks as a new class of sensitized solar cells

A series of Ru(ii)L2L? (L = 2,2?-bipyridyl, L? = 2,2?-bipyridine-5,5?-dicarboxylic acid), RuDCBPY, -containing zirconium(iv) coordination polymer thin films have been prepared as sensitizing materials for solar cell applications. These metal-organic framework (MOF) sensitized solar cells, MOFSCs, each are shown to generate photocurrent in response to simulated 1 sun illumination. Emission lifetime measurements indicate the excited state quenching of RuDCBPY at the MOF-TiO2 interface is extremely efficient (>90%), presumably due to electron injection into TiO2. A mechanism is proposed in which RuDCBPY-centers photo-excited within the MOF-bulk undergo isotropic energy migration up to 25 nm from the point of origin. This work represents the first example in which a MOFSC is directly compared to the constituent dye adsorbed on TiO2 (DSC). Importantly, the MOFSCs outperformed their RuDCBPY-TiO2 DSC counterpart under the conditions used here and, thus, are solidified as promising solar cell platforms.

Electrochemiluminescent peptide nucleic acid-like monomers containing Ru(II)-dipyridoquinoxaline and Ru(II)-dipyridophenazine complexes

A series of Ru(II)-peptide nucleic acid (PNA)-like monomers, [Ru(bpy) 2(dpq-L-PNA-OH)]2+ (M1), [Ru(phen)2(dpq-L-PNA- OH)]2+ (M2), [Ru(bpy)2(dppz-L-PNA-OH)]2+ (M3), and [Ru(phen)2(dppz-L-PNA-OH)]2+ (M4) (bpy = 2,2?-bipyridine, phen = 1,10-phenanthroline, dpq-L-PNA-OH = 2-(N-(2-(((9H-fluoren-9-yl)methoxy)carbonylamino)ethyl)-6-(dipyrido[3,2-a: 2?,3?-c]phenazine-11-carboxamido)hexanamido)acetic acid, dppz-L-PNA-OH = 2-(N-(2-(((9H-fluoren-9-yl) methoxy)carbonylamino)ethyl)-6- (dipyrido[3,2-f:2?,3?-h]quinoxaline-2-carboxamido)acetic acid) have been synthesized and characterized by IR and 1H NMR spectroscopy, mass spectrometry, and elemental analysis. As is typical for Ru(II)-tris(diimine) complexes, acetonitrile solutions of these complexes (M1-M4) show MLCT transitions in the 443-455 nm region and emission maxima at 618, 613, 658, and 660 nm, respectively, upon photoexcitation at 450 nm. Changes in the ligand environment around the Ru(II) center are reflected in the luminescence and electrochemical response obtained from these monomers. The emission intensity and quantum yield for M1 and M2 were found to be higher than for M3 and M4. Electrochemical studies in acetonitrile show the Ru(II)-PNA monomers to undergo a one-electron redox process associated with RuII to RuIII oxidation. A positive shift was observed in the reversible redox potentials for M1-M4 (962, 951, 936, and 938 mV, respectively, vs Fc 0/+ (Fc = ferrocene)) in comparison with [Ru(bpy)3] 2+ (888 mV vs Fc0/+). The ability of the Ru(II)-PNA monomers to generate electrochemiluminescence (ECL) was assessed in acetonitrile solutions containing tripropylamine (TPA) as a coreactant. Intense ECL signals were observed with emission maxima for M1-M4 at 622, 616, 673, and 675 nm, respectively. At an applied potential sufficiently positive to oxidize the ruthenium center, the integrated intensity for ECL from the PNA monomers was found to vary in the order M1 (62%) > M3 (60%) > M4 (46%) > M2 (44%) with respect to [Ru(bpy)3]2+ (100%). These findings indicate that such Ru(II)-PNA bioconjugates could be investigated as multimodal labels for biosensing applications.

XPS studies of Ru-polypyridine complexes for solar cell applications

A series of Ru-polypyridine dyes has been studied with electron spectroscopy using AlKalpha and synchrotron radiation. Both pure complexes and complexes adsorbed on nanostructured TiO2 (anatase) surfaces have been examined and special emphasis was given to the dye complex cis-bis(4,4?-dicarboxy-2,2?-bipyridine)-bis-(isothiocyanato)- ruthenium(II) [Ru(dcbpy)2(NCS)2]. The measurements provide information concerning the energy level matching between the dyes and the TiO2, which is of importance in photoinduced charge transfer reactions and in applications such as dye-sensitized solar cells. The measurements also support the general picture of bonding of carboxylated complexes to the surfaces via the carboxyl groups of a single bi-isonicotinic acid ligand, and that, for Ru(dcbpy)2(NCS)2, the NCS-ligand-TiO2 interaction is small. Corroborative support is provided via quantum chemical calculations on the ligand (bi-isonicotinic acid) adsorbed on a TiO2 anatase (101) surface.
