2,2-Bipyridine ligands bearing functionalised aryl substituents have been prepared with the aim of subsequent functionalisation and the preparation of multinuclear metallostars. The key intermediates are compounds containing 4-methoxyphenyl substituents which may be converted to 4-hydroxyphenyl substituted ligands.

Oxidation of Bromide to Bromine by Ruthenium(II) Bipyridine-Type Complexes Using the Flash-Quench Technique

Six ruthenium complexes, [Ru(bpy)3]2+ (1), [Ru(bpy)2(deeb)]2+ (2), [Ru(deeb)2(dmbpy)]2+ (3), [Ru(deeb)2(bpy)]2+ (4), [Ru(deeb)3]2+ (5), and [Ru(deeb)2(bpz)] 2+ (6) (bpy: 2,2?-bipyridine; deeb: 4,4?-diethylester-2,2?-bipyridine; dmbpy: 4,4?-dimethyl-2,2?-bipyridine, bpz: 2,2?-bipyrazine), have been employed to sensitize photochemical oxidation of bromide to bromine. The oxidation potential for complexes 1-6 are 1.26, 1.36, 1.42, 1.46, 1.56, and 1.66 V vs SCE, respectively. The bimolecular rate constants for the quenching of complexes 1-6 by ArN2+ (bromobenzenediazonium) are determined as 1.1 ¡Á 109, 1.6 ¡Á 108, 1.4 ¡Á 108, 1.2 ¡Á 108, 6.4 ¡Á 107, and 8.9 ¡Á 106 M-1 s-1, respectively. Transient kinetics indicated that Br- reacted with photogenerated Ru(III) species at different rates. Bimolecular rate constants for the oxidation of Br- by the Ru(III) species derived from complexes 1-5 are observed as 1.2 ¡Á 108, 1.3 ¡Á 109, 4.0 ¡Á 109, 4.8 ¡Á 109, and 1.1 ¡Á 1010, M-1 s-1, respectively. The last reaction kinetics observed in the three-component system consisting of a Ru sensitizer, quencher, and bromide is shown to be independent of the Ru sensitizer. The final product was identified as bromine by its reaction with hexene. The last reaction kinetics is assigned to the disproportionation reaction of Br2-? ions, for which the rate constant is determined as 5 ¡Á 109 M-1 s-1. Though complex 6 has the highest oxidation potential in the Ru(II)/Ru(III) couple, its excited state fails to react with ArN2+ sufficiently for subsequent reactions. The Ru(III) species derived from complex 1 reacts with Br- at the slowest rate. Complexes 2-5 are excellent photosensitizers to drive photooxidation of bromide to bromine.

Electron-transfer chemistry of Ru-linker-(heme)-modified myoglobin: Rapid intraprotein reduction of a photogenerated porphyrin cation radical

We report the synthesis and characterization of RuC7, a complex in which a heme is covalently attached to a [Ru(bpy)3]2+ complex through a -(CH2)7- linker. Insertion of RuC7 into horse heart apomyoglobin gives RuC7Mb, a Ru(heme)-protein conjugate in which [Ru(bpy)3]2+ emission is highly quenched. The rate of photoinduced electron transfer (ET) from the resting (Ru2+/Fe 3+) to the transient (Ru3+/Fe2+) state of RuC7Mb is > 108 s-1; the back ET rate (to regenerate Ru2+/Fe3+) is 1.4 ¡Á 107 s-1. Irreversible oxidative quenching by [Co(NH3)5Cl] 2+ generates Ru3+/ Fe3+: the Ru3+ complex then oxidizes the porphyrin to a cation radical (P.+); in a subsequent step, P.+ oxidizes both Fe3+ (to give Fe IV=O) and an amino acid residue. The rate of intramolecular reduction of P.+ is 9.8 ¡Á 103 s-1; the rate of ferryl formation is 2.9 ¡Á 103 s-1. Strong EPR signals attributable to tyrosine and tryptophan radicals were recorded after RuC7MbM3+ (M = Fe, Mn) was flash-quenched/frozen.

A 3-pyridyl-5,15-diazaporphyrin nickel(II) complex as a bidentate metalloligand for transition metals

3-Pyridyl-5,15-diazaporphyrin nickel(II) serves as a bidentate metalloligand for platinum(II), ruthenium(II), and rhenium(I) metal centers. Single-crystal X-ray diffraction analysis of these metal complexes unambiguously reveals the presence of a dative bond between the outer metal center and the meso-nitrogen atom. The UV/Vis absorption spectra of the complexes show substantially red-shifted bands which are perturbed by outer-metal coordination. This is due to the contribution of metal-to-ligand charge transfer interactions.

Synthesis and complexation of macrocycles containing two pyrazolone sub-units

The synthesis and characterization of several Ru(II) complexes with acyclic and macrocyclic ligands containing tautomerizable OH and fixed OCH3 5-pyrazolone heterocycles are described. From dipyrazolylmethane bidentate ligands L, RuL(bpy)2(PF6)2 and Ru(L-H+)(bpy)2PF6 complexes have been obtained. From the macrocycle with two CH3 and two OCH3 pyrazole sub-units, a series of complexes Ru(Mac)XY(PF6)2 (X,Y = DMSO, CH3CN, Py, Pz, dmPz) has been prepared. They show a behavior close to that of the analogous tetrapyrazole complexes but with slightly different complexing ability. In the case of the corresponding di OH macrocycle, coordination with Ru(DMSO)4Cl2 leads to unstable complexes.

Metallo-Supramolecular Gels that are Photocleavable with Visible and Near-Infrared Irradiation

A photolabile ruthenium-based complex, [Ru(bpy)2(4AMP)2](PF6)2, (4AMP=4-(aminomethyl)pyridine) is incorporated into polyurea organo- and hydrogels via the reactive amine moieties on the photocleavable 4AMP ligands. While showing long-term stability in the dark, cleavage of the pyridine?ruthenium bond upon irradiation with visible or near-infrared irradiation (in a two-photon process) leads to rapid de-gelation of the supramolecular gels, thus enabling spatiotemporal micropatterning by photomasking or pulsed NIR-laser irradiation.

Orientation tuning of a polypyridyl Ru(II) complex immobilized on a clay surface toward chiral discrimination

The present work reports an attempt to elucidate a stereoselective energy-transfer system by immobilizing a chiral metal complex on a clay surface. The metal complex used was [Ru(bpy)2Li]2+ with L1 = bpy (2,2a??-bipyridine), L2 = 4,4a??-diundecyl-2,2a??-bipyridine, and L3 = 5,5a??-diundecyl-2,2a??-bipyridine. The adsorption structure of [Ru(bpy)2Li]2+ was studied by means of electric dichroism measurements on an aqueous dispersion of a colloidal clay. It was found that the molecular orientation of the adsorbed Ru(II) complex was affected remarkably by the positions of the alkyl chains on the bpy ligand; that is, the angle of the 3-fold or pseudo-3-fold symmetry axis of the Ru(II) complex with respect to the surface normal was obtained to be 24A, 30A, and 52A for i = 1, 2, and 3, respectively. The efficiency of the energy-transfer was determined by photoluminescence quenching measurements between the adsorbed Ru(II) complex and [Ru(acac)3] (acac = acetylacetonate) in solution. As a result, stereoselectivity appeared most for the case of [Ru(bpy) 2L3]2+ in which its two helically twisted bpy ligands were projected in an outward direction. A 2005 American Chemical Society.
