Irradiation of rac-[Ru(bpy)2(PhP(OMe)2)(Cl)]Cl (2) at lambdat > 460 nm results in the photochromic generation of a new atropisomer and chirality inversion, via rotation of the PhP(OMe)2 moiety around the Ru-P bond. However, since the energetic barrier to rotation is low resulting in racemization, it was found that the formation of a supramolecular complex between 2 and gamma-cyclodextrin (gamma-CDx) facilitated the stabilization of the new atropisomeric conformation. On irradiation the bisignate signals in the circular dichroism spectrum of the 2:gamma-CDx complex were converted to an entirely new and distinct circular dichroism spectrum, as a result of a different spatial orientation of the phenyl electronic transition in the PhP(OMe)2 moiety (the active circular dichroism spectra were found to arise from different g factor values of the Delta-2:gamma-CDx and Lambda-2:gammaCDx complexes). The new atropisomer formation and subsequent thermally induced interconversion could be further detected by conventional and variable temperature 1H NMR studies. Determination of the conformation of the new atropisomer was achieved by combining analysis of the changes in the circular dichroism spectra by exciton coupling theory with molecular modeling and DFT calculations.

The coordination behavior and fluorescence spectra of pyrene-appended Schiff bases and the ruthenium(II) complexes were studied. The study was done with two generic types of ruthenium(II) precursor with different set of Lewis base ligands. The Lewis base ligands chosen were (i) 2,2?-bipyridine and (ii) triphenyl phosphine and carbonyl together. The molecular structures of two of the complexes were studied by X-ray crystallography. The effect of these two different set of ligands as well as the Schiff base ligands on the fluorescence spectra of the complexes in organic solvent were compared.

A document type is Article, introducing its new discovery.

To develop metallosurfactant-based fluorescent aggregates, it is important to understand the impact of the head and tail parts on the self-assembly behaviour. Herein, a new series of water soluble, emissive double chain surfactant-ruthenium(ii) complexes differing in their head group size and chain length, [Ru(bpy)2(DA)2]Cl2 (1), [Ru(bpy)2(HA)2]Cl2 (2), [Ru(phen)2(DA)2]Cl2 (3), [Ru(phen)2(HA)2]Cl2 (4), where bpy = 2,2?-bipyridyl, phen = 1,10-phenanthroline, DA = dodecylamine and HA = hexadecylamine, has been synthesized and characterized. For the complexes 1-4, hydrophobicity behaviour, critical aggregation concentration (CAC), thermodynamics of the aggregation (deltaGa, deltaHa, deltaSa), and the average size distribution, morphology and stability of the aggregates have been evaluated. The obtained results have shown that the increase in chain length as well as the size of the aromatic head group decreases the CAC values in the order of the complexes 1 > 2 > 3 > 4, whereas those changes increase the hydrophobicity and the average size distribution. The thermodynamics of the aggregation indicated that the process is kinetically controlled, spontaneous, exothermic and entropy driven. The self-assembled surfactant-ruthenium(ii) complexes are preferably spherical and belong to the vesicles family being green emissive and monodisperse and showing narrow size distribution and excellent stability in aqueous medium. The enlargement of vesicle size is noted upon increasing the head size as well as the chain length, but the former influences to a greater extent. This type of fluorescent metallovesicles can be used for biomedical and material applications in near future.

In an article, published in an article, once mentioned the application of 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer,molecular formula is C12H12Cl4Ru2, is a conventional compound. this article was the specific content is as follows.HPLC of Formula: C12H12Cl4Ru2

The rate and mechanism of substitution in the Ru(II) complexes (C1?C6) by thiourea nucleophiles was studied at pH 2 and rate constants measured as a function of nucleophile concentrations and temperature using spectrometric methods. There is increased electron density at the Ru metal atom of C2 as a result of inductive donation by substituents on the arene ligand, making it less positive and therefore less reactive than C1. For the complexes C3?C6 bearing the 2,2?-bipyridyl ligand, the aqua ligands are located trans to the arene ligands, and hence, their reactivity increases in accordance to the number and type of alkyl substituents on the eta6-arene ligands which donate inductively into the pi-molecular orbitals, causing increased trans labialisation of the coordinated aquo co-ligand. Compared to the reactivity of triaquo complex (C1), the auxiliary bipyridyl ligand of (C3) complex lowers the rate of substitution for the later complex by a factor of about 100, possibly due to its steric hindrance at the Ru(II) metal centre. The significantly negative activation entropies and positive activation enthalpies suggest an associative mode of substitution. The reactivity of the nucleophiles follow the order DMTU > TU > TMTU.

A diastereomerically mixed complex [Ru{(S)-phgly}2{(¡À)- biphep}] is readily prepared from achiral diphosphine BIPHEP in two steps. These diastereomers are then separated by silica gel column chromatography. A 61:39 equilibrium mixture of [Ru{(S)-phgly}2{(S)-biphep}] and [Ru{(S)-phgly}2{(R)-biphep}] with Li2CO3 is used to catalyze cyanosilylation of benzaldehyde to afford the R cyanated product in 92% ee. The enantioselectivity is just slightly lower than that by using the pure [Ru{(S)-phgly}2{(S)-biphep}]/Li2CO 3 catalyst system of 96%. The high enantioselective ability of the diastereomerically mixed catalyst is revealed through a series of kinetic experiments in which the highly enantioselective [Ru{(S)-phgly} 2{(S)-biphep}]/Li2CO3 system is shown to catalyze the reaction 16.8 times faster than the less selective [Ru{(S)-phgly}2{(R)-biphep}]/Li2CO3 system, affording the product in 2.6% ee. An equation is derived to approximate the relationship between the diastereomeric ratio of the catalyst and the ee value of the product.
