Electrochemistry of ruthenium(II) complexes of 8-aminoquinoline

Oxidation of [Ru(NH2Q)3]2+ (NH 2Q = 8-aminoquinoline) results in intermolecular coupling of 8-aminoquinoline ligands to yield an electroactive polymer. Oxidative polymerization is not observed for [Ru(bpy)2(NH2Q)] 2+ (bpy = 2,2?-bipyridine), where only one 8-aminoquinoline ligand is present.

Drastic difference in the photo-driven hydrogenation reactions of ruthenium complexes containing NAD model ligands

Successful control of photo-driven NAD+/NADH type hydrogenation reactions in ruthenium complexes has been accomplished by using a new NAD + model ligand with modulated distortion of the ligand taking advantage of the substituent effect.

Tris-chelate complexes with chiral ligands: In search of diastereoisomeric selectivity with remote stereogenic centres

Photoactivation of Cu Centers in Metal-Organic Frameworks for Selective CO2 Conversion to Ethanol

CO2 hydrogenation to ethanol is of practical importance but poses a significant challenge due to the need of forming one C-C bond while keeping one C-O bond intact. CuI centers could selectively catalyze CO2-to-ethanol conversion, but the CuI catalytic sites were unstable under reaction conditions. Here we report the use of low-intensity light to generate CuI species in the cavities of a metal-organic framework (MOF) for catalytic CO2 hydrogenation to ethanol. X-ray photoelectron and transient absorption spectroscopies indicate the generation of CuI species via single-electron transfer from photoexcited [Ru(bpy)3]2+-based ligands on the MOF to CuII centers in the cavities and from Cu0 centers to the photoexcited [Ru(bpy)3]2+-based ligands. Upon light activation, this Cu-Ru-MOF hybrid selectively hydrogenates CO2 to EtOH with an activity of 9650 mumol gCu-1 h-1 under 2 MPa of H2/CO2 = 3:1 at 150 C. Low-intensity light thus generates and stabilizes CuI species for sustained EtOH production.

Probing the excited states of Ru(II) complexes with dipyrido[2,3-a:3′,2′-c]phenazine: A transient resonance raman spectroscopy and computational study

The lifetimes and transient resonance Raman spectra for Ru(II) complexes with the dipyrido[2,3-a:3′,2′-c]-phenazine (ppb) ligand and substituted analogues have been measured. The effect of altering the Ru(II) center ({Ru(CN)4}2- versus {Ru(bpy)2}2+), of the complex, on the excited-state lifetimes and spectra has been considered. For [Ru(bpy)2L]2+ complexes the excited-state lifetimes range from 124 to 600 ns in MeCN depending on the substituents on the ppb ligand. For the [Ru(CN)4L]2- complexes the lifetimes in H2O are approximately 5 ns. The transient resonance Raman spectra for the MLCT excited states of these complexes have been measured. The data are analyzed by comparison with the resonance Raman spectra of the electrochemically reduced [(PPh3)2Cu(mu-L *-)Cu(PPh3)2]+ complexes. The vibrational spectra of the complexes have been modeled using DFT methods. For experimental ground-state vibrational spectra of the complexes the data may be compared to calculated spectra of the ligand or metal complex. It is found that the mean absolute deviation between experimental and calculated frequencies is less for the calculation on the respective metal complexes than for the ligand. For the transient resonance Raman spectra of the complexes the observed vibrational bands may be compared with those of the calculated ligand radical anion, the reduced complex [Ru(CN)4L*-] 3-, or the triplet state of the complex. In terms of a correlation with the observed transient RR spectra, calculations on the metal complex models offered no significant improvement compared to those based on the ligand radical anion alone. In all cases small structural changes are predicted on going from the ground to excited state.

Light-initiated hydroxylation of lauric acid using hybrid P450 BM3 enzymes

We have developed hybrid P450 BM3 enzymes consisting of a Ru(ii)-diimine photosensitizer covalently attached to non-native single cysteine residues of P450 BM3 heme domain mutants. These enzymes are capable, upon light activation, of selectively hydroxylating lauric acid with 40 times higher total turnover numbers compared to the peroxide shunt.

Ruthenium polypyridine complexes of tris-(2-pyridyl)-1,3,5-triazine – Unusual building blocks for the synthesis of photochemical molecular devices

The mononuclear compounds bis-(2,2?-bipyridine)ruthenium(ii)-(tris(2- pyridyl)triazine) [(bpy)2Ru(tpt)](PF6)21 and bis-(4,4?-di-tert-butyl-2,2?-bipyridine)ruthenium(ii) -(tris(2-pyridyl)triazine) [(tbbpy)2Ru(tpt)](PF6) 22 have been synthesised and fully characterised. The attempted syntheses of heterodinuclear complexes with the tris(2-pyridyl)triazine (tpt) ligand as bridging ligand and various palladium(ii)- and platinum(ii)-dichloro complexes using the ruthenium complexes as starting materials resulted in a partial hydrolysis of the triazine based bridging ligand in case of 2 and an unselective decomposition in case of 1. Compound 2 reacts with Pd(DMSO) 2Cl2 and Pt(DMSO)2Cl2 substituting three ligands from the metal centres of these precursors with partial hydrolysis of the triazine moiety of the bridging ligand yielding the dinuclear complexes bis-(4,4?-di-tert-butyl-2,2?-bipyridine)ruthenium(ii) -N-((picolinamido)(pyridin-2-yl)methylene)picolinamide)chloro-palladium(ii) [(tbbpy)2Ru(tptO)PdCl](PF6)23 and bis-(4,4?-di-tert-butyl-2,2?-bipyridine) ruthenium(ii)-N- ((picolinamido)(pyridin-2-yl)methylene)picolinamide)chloro-platinum(ii) [(tbbpy)2Ru(tptO)PtCl](PF6)24. The newly formed bridging ligand coordinates in a bidentate fashion at the ruthenium centre and acts as a tridentate ligand for the second metal centre. The structures of all the complexes have been fully characterised and their photophysical properties are reported. A similar reaction sequence using the (4?-(p-bromophenyl)-2, 2?:6?,2?-terpyridine)ruthenium(ii)-(tris(2-pyridyl)triazine) complex [(BrPhtpy)Ru(tpt)](PF6)25 and Pd(CH 3CN)2Cl2 as starting materials did not yield the hydrolysed bridging ligand but the expected dinuclear complex [(BrPhtpy)Ru(tpt)PdCl2](PF6)26 suggesting that the coordination of two pyridine rings of the tpt by the ruthenium centre is essential for the stabilisation of the tpt frame work. Preliminary investigations show that the dinuclear ruthenium-palladium and -platinum complexes are not active catalysts in the light-driven hydrogen production. The Royal Society of Chemistry 2009.

Photochemistry of ruthenium trisbipyridine functionalized on gold nanoparticles

Design of nanohybrid systems possessing several ruthenium trisbipyridine (Ru(bpy)32+) chromophores on the surface of gold nanoparticles, by adopting a place exchange reaction, was reported and their photophysical properties were tuned by varying the density of chromophores. The charge shift between the excited and ground-state Ru(bpy)3 2+ chromophores was reported for the first time, leading to the formation of Ru(bpy)32+ and Ru(bpy)3 3+. Electron-transfer products were not observed on decreasing the concentration of Ru(bpy)32+ functionalized on Au nanoparticles or in a saturated solution of unbound chromophores. The close proximity of the chromophores on periphery of the gold core may lead to an electron transfer reaction and the products sustained for several nanoseconds before undergoing recombination, probably due to the stabilizing effect of the polar ethylene glycol moieties embedded between the chromophore groups.

[Ru(bpy)2(bqdiBr2)](PF6)2 bearing a 3,6-dibromo-1,2-benzoquinone diimine ligand (bqdiBr2 = Br-C6H2(NH)2-Br): Synthesis and its cross coupling reactions with organostannanes and organoboronic acids

[Ru(bpy)2(bqdiBr2)](PF6)2 ([1](PF6)2, bpy = 2,2?-bipyridyl, bqdiBr2 = 3,6-dibromo-1,2-benzoquinone diimine) was synthesized by the reaction of 3,6-dibromo-1,2-phenylenediamine with [RuCl2(bpy)2] in air, and the reactivity of [1](PF6)2 in Pd-catalyzed cross-coupling reactions with metalated thiophene and benzene was investigated. The structure of [1](PF6)2 was determined using X-ray crystallography. The Migita-Kosugi-Stille cross-coupling of [1](PF 6)2 with 2 equiv of Th-SnBu3 (Th = 2-thienyl; Bu = butyl) afforded a 3,6-di(2-thienyl)-1,2-benzoquinone diimine (Th-C 6H2(NH)2-Th)-coordinated Ru(II) complex [2](PF6)2. Similarly, the Suzuki-Miyaura cross-coupling of [1](PF6)2 with 2 equiv of CH3OC 6H4-B(OH)2-p proceeded smoothly to afford a p-CH3OC6H4-C6H2(NH) 2-C6H4OCH3-p-coodinated Ru(II) complex, [3](PF6)2. The optical and electrochemical properties of these complexes were evaluated based on the presence of the extended pi-conjugated diimine ligand in the diimine moiety. The Stille cross-coupling of [1](PF6)2 with 1 equiv of Me 3Sn-C4H2S-SnMe3 (C4H 2S: thiophene-2,5-diyl) afforded a pi-conjugated polymer consisting of the [Ru(bpy)2(bqdi)]2+ units.
