Abstract: Cross-fertilization between molecular magnetism and organic spintronics is leading to the development of concepts based on the use of molecules as active elements to influence spin-related transport processes. The research on hybrid devices, where the magnetic molecules in contact with the electrodes influence the spin and charge injection and transport, is moving its first steps but is expected to quickly expand the technological potential of molecular spintronics and quantum computing. New exciting possibilities, linked to the individual properties of these molecular units and to their interaction with novel substrates, are getting disclosed. The chemical functionalization of these molecules is the tool which allows to tune their electronic and magnetic properties and to directly create these hybrid architectures. However, the coupling of molecules with the spin transport phenomena is far from being trivial. First, the stability of molecules in the device environment must be tested and, subsequently, the organization of molecules in the desired architectures must be mastered permitting a careful control of the interactions between inorganic substrates and molecular layers. Here we summarize how this research activity can be developed in the case of one of the simplest magnetic molecules, an organic radical. We will start from an innocent surface, such as gold, to move then toward a real-device environment. We evidence how these efforts can result in a surface-specific molecular-based method to influence the spin injection and transport phenomena, paving the way for developing new devices in which a fine-tuning of magnetic features is required.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.13815-94-6, Name is Ruthenium(III) chloride trihydrate, molecular formula is Cl3H6O3Ru. In a Article，once mentioned of 13815-94-6, category: ruthenium-catalysts

cis-[Ru(Hmcpq)2(NCS)2] (1; Hmcpq=4-carboxy-2-(2?-pyridyl)quinoline) was newly synthesized, and its spectral (absorption, luminescence) and electrochemical properties were compared with those of cis-[Ru(H2dcpq)2(NCS)2] (2; H2dcpq=4-carboxy-2-[2?-(4?-carboxypyridyl)]quinoline). Solar cells based on nanocrystalline TiO2 film sensitized with 1 showed efficient photosensitization over a large portion of the visible and near-IR spectral region. These solar cells generated a large short-circuit photocurrent (12 mA cm-2), produced an open-circuit voltage of 0.53 V, and exhibited a solar energy conversion efficiency of 4.6% under simulated AM 1.5 solar irradiation (100 mW cm-2). The effects of the number of carboxyl groups in 1 and 2 on the binding to nanocrystalline TiO2 and on the photovoltaic performance of the solar cells were investigated.

Reactions of 3,6-bis(2-pyridyl)-4-phenylpyridazine (Lph) with [(eta6-arene)Ru(mu-Cl)Cl]2 (arene = C6H6, p-iPrC6H4Me and C6Me6), [(eta5-C5Me5)M(mu-Cl)Cl]2, (M = Rh and Ir) and [(eta5-Cp)Ru(PPh3)2Cl] (Cp = C5H5, C5Me5 and C9H7) afford mononuclear complexes of the type [(eta6-arene)Ru(Lph)Cl]PF6, [(eta5-C5Me5)M(Lph)Cl]PF6 and [(Cp)Ru(Lph)(PPh3)]PF6 with different structural motifs depending on the pi-acidity of the ligand, electronic properties of the central metal atom and nature of the co-ligands. Complexes [(eta6-C6H6)Ru(Lph)Cl]PF6 1, [(eta6-p-iPrC6H4Me)Ru(Lph)Cl]PF6 2, [(eta5-C5Me5)Ir(Lph)Cl]PF6 5, [(eta5-Cp)Ru(PPh3)(Lph)]PF6, (Cp = C5H5, 6; C5Me5, 7; C9H7, 8) show the type-A binding mode (see text), while complexes [(eta6-C6Me6)Ru(Lph)Cl]PF6 3 and [(eta5-C5Me5)Rh(Lph)Cl]PF6 4 show the type-B binding mode (see text). These differences reflect the more electron-rich character of the [(eta6-C6Me6)Ru(mu-Cl)Cl]2 and [(eta5-C5Me5)Rh(mu-Cl)Cl]2 complexes compared to the other starting precursor complexes. Binding modes of the ligand Lph are determined by 1H NMR spectroscopy, single-crystal X-ray analysis as well as evidence obtained from the solid-state structures and corroborated by density functional theory calculations. From the systems studied here, it is concluded that the electron density on the central metal atom of these complexes plays an important role in deciding the ligand binding sites.

A document type is Article, introducing its new discovery.

Olefin metathesis is now one of the most efficient ways to create new carbon-carbon bonds. While most efforts focused on the development of ever-more efficient catalysts, a particular attention has recently been devoted to developing latent metathesis catalysts, inactive species that need an external stimulus to become active. This furnishes an increased control over the reaction which is crucial for applications in materials science. Here, we report our work on the development of a new system to achieve visible-light-controlled metathesis by merging olefin metathesis and photoredox catalysis. The combination of a ruthenium metathesis catalyst bearing two N-heterocyclic carbenes with an oxidizing pyrylium photocatalyst affords excellent temporal and spatial resolution using only visible light as stimulus. Applications of this system in synthesis, as well as in polymer patterning and photolithography with spatially resolved ring-opening metathesis polymerization, are described.

Synthesis of new half-sandwich ruthenium (II) complexes of the type [Ru (eta6-arene) (L)Cl] (arene = benzene or p-cymene; L = 1-pyrene-carboxaldehye benzhydrazone ligands) has been described. The synthesised complexes were completely characterised by elemental analysis and spectral (FT-IR, UV?vis, Emission, NMR and HRMS) methods. The isolated arene Ru(II) complexes are fluorescent in nature resulting the emission maxima observed in the visible region. The solid state molecular structures of the complexes 1, 2, 3 and 5 evidence that the ligands coordinate to ruthenium in a chelating kappa2 N, O- bidentate fashion, and shows the presence of typical pseudo-octahedral geometry. The potential of the complexes to act as anticancer agents are thoroughly screened on breast adenocarcinoma MCF-7, lung adenocarcinoma A549 and NIH-3T3 cell lines by in vitro experimental conditions. The anticancer activity of complex 4 is found to be remarkable towards A549 with high selectivity index and low IC50 values compared to cisplatin. The differences in biological activity of the complexes were explained on the basis of partition coefficient values and differences in the energy of ruthenium?chloride bonds. Further, AO/EB, Hoechst 33258 and flow cytometry analyses indicate that present ruthenium complexes cause cell death only via apoptosis mechanism. The DNA content in cell cycle distribution was analysed by flow cytometry which shows that complex 4 suppress the cell growth in A549 cells at sub G0/G1 phase region, indicative of apoptotic cells. This study outlines the preliminary steps towards understanding the mechanism of action with a new class of ruthenium-based chemotherapeutics.

An enhanced photoluminescence is observed upon addition of organic guests to the trimeric macrocycle (see picture; tpy = 2,2′:6′,2”- terpyridine). The use of a short alkyne bridge has enabled the rigid trimer and the smaller dimer to be prepared with controllable cavity sizes. A better redox communication between the Ru centers in the dimer is also observed.

The stereoselective total synthesis of (-)-microcarpalide, a recently discovered 10-membered lactone of fungal origin displaying a remarkable disrupting action on actin microfilaments, was accomplished by using ring-closing metathesis (RCM) as the key step for the formation of the medium-sized ring. The diene ester required for the macrocyclization reaction was assembled via DCC-mediated esterification of two suitable partners, each bearing a terminal alkene group. The alcohol fragment was synthesized from n-bromohexane through a seven-step sequence entailing two consecutive stereoselective homologations of chiral boronic esters as strategic transformations for the sequential insertion of the two stereocentres with the final S absolute configuration, using (+)-pinanediol as the chiral director; final elaboration to the desired C11 framework envisaged treatment with an allyl Grignard reagent and oxidative cleavage of the boronic scaffold. In contrast, the acidic fragment was prepared in ten steps from D-tartaric acid, whose C4 backbone was elongated to the required C7 skeleton by means of two distinct Swern-Wittig oxidation-homologation sequences.
