Photoactivated anticancer chemotherapy distinguishes itself by its high selectivity by virtue of the spatiotemporal control of irradiation. However, short photoactivation wavelengths limit its application. Herein, an amphiphilic Ru(ii) complex, cis-[Ru(bpy)2(C18H37CN)2]2+ (bpy = 2,2?-bipyridine), was embedded along with a poly(ethylene glycol, PEG)-modified lipid onto the surfaces of oleate-capped lanthanide-doped upconversion nanoparticles (UCNPs). The resultant core-shell hybrid system is water-dispersible, stable in the dark, and releases a DNA covalent-binding agent of [Ru(bpy)2(H2O)2]2+ upon 980 nm laser irradiation, providing guidelines for developing near-infrared (NIR) light triggered chemotherapeutics.

Synthetic Route of 15746-57-3. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II). In a document type is Article, introducing its new discovery.

A series of cyclometalated RuII coordination compounds of the general structural formula [Ru(bpy)2(C^N)]PF6 {C^N = 2-phenylpyridine (1), 2-(2,4-difluorophenyl)pyridine (2), 2-(4-methoxyphenyl)-5- methylpyridine (3), benzo[h]quinoline (4); bpy = 2,2′-bipyridine} have been synthesized, structurally and electrochemically characterized, and examined by using a battery of spectroscopic techniques. The combination of static and dynamic photoluminescence at room temperature and 77 K, resonance Raman spectroscopy, cyclic voltammetry, spectroelectrochemistry, and ultrafast transient absorption spectroscopy reveal that – although the nature of the cyclometalating ligand substantially affects the oxidation potential at the metal center – the lowest-energy metal-to-ligand charge-transfer excited state always retains pure Ru?bpy character across this series of molecules, and the cyclometalating subunit plays the role of ancillary ligand. Cyclometalated RuII coordination compounds of the general formula [Ru(bpy) 2(C^N)]PF6 {C^N = 2-phenylpyridine (1), 2-(2,4-difluorophenyl)pyridine (2), 2-(4-methoxyphenyl)-5-methylpyridine (3), benzo[h]quinoline (4); bpy = 2,2′-bipyridine} have been synthesized, structurally and electrochemically characterized, and examined with spectroscopic techniques including ultrafast transient absorption.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a Article，once mentioned of 15746-57-3, Computed Properties of C20H16Cl2N4Ru

A new polyazamacrocycle (L) containing two 2,2?-bipyridino (bpy) units, where the heteroaromatic nitrogen atoms point outwards from the macrocyclic cavity, was synthesized and characterized by elemental analysis, ESI-MS, 1H and 13C NMR, FTIR and TGA. Five protonation constants involving aliphatic nitrogens with log K in the range 9.39-3.07 were determined by potentiometry and NMR and a sixth protonation (log K = 2.2) involving a bipyridine moiety could be detected by UV-Vis and NMR titrations. The interaction of L with the cyanometallate anions [Pt(CN)4] 2- and [Co(CN)6]3- was studied by potentiometry yielding respectively log K values in the ranges 4.0-6.4 and 5.2-10.5, covering protonation degrees from 1 to 5. Studies on L with [Ru(CN)6] 4- led to early precipitation preventing potentiometry, but crystals of [H4L][Ru(CN)6]·10H2O and also of [H2L](ClO4)2·4H2O suitable for X-ray diffraction could be obtained and the crystalline structures are described. The interaction of L with Zn2+ was investigated by potentiometry and UV-Vis showing the formation of mono- and dinuclear complexes involving the bipyridines. The macrocycle was used as a bridging ligand for the successful synthesis of a new dinuclear [(Ru(bpy)2) 2(L)](PF6)4·4HPF6 complex that was fully characterized. The protonation (log K in the range 9.9-1.6) and coordination features of this compound towards Cu2+ and Zn 2+ were explored by UV-Vis absorption and emission spectroscopies.

Electric Literature of 15746-57-3, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a patent, introducing its new discovery.

Electronic coupling across a bridging ligand between a chromophore and a catalyst center has an important influence on biological and synthetic photocatalytic processes. Structural and associated electronic modifications of ligands may improve the efficiency of photocatalytic transformations of organic substrates. Two ruthenium-based supramolecular assemblies based on a chromophore-catalyst dyad containing a Ru-aqua complex and its chloro form as the catalytic components were synthesized and structurally characterized, and their spectroscopic and electrochemical properties were investigated. Under visible light irradiation and in the presence of [Co(NH3)5Cl]Cl2 as a sacrificial electron acceptor, both complexes exhibited good photocatalytic activity toward oxidation of sulfide into the corresponding sulfoxide with high efficiency and >99% product selectivity in neutral aqueous solution. The Ru-aqua complex assembly was more efficient than the chloro complex. Isotopic labeling experiments using 18O-labeled water demonstrated the oxygen atom transfer from the water to the organic substrate, likely through the formation of an active intermediate, Ru(IV)=O.

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.

Targeted delivery of clinically approved anticancer drug to tumor sites is an effective way to achieve enhanced drug efficacy as well as reduced side effects and toxicity. Here bicalutamide is caged by the Ru(II) center through the nitrile group, and three photoactive Ru(II) complexes were designed and synthesized. Docking study showed that the ruthenium(II) fragments can effectively block the binding of complexes 1?3 with AR (androgen receptor) owing to the large steric structures, thus bicalutamide in complexes 1?3 could not interact with AR-LBD (ligand binding domain). Once irradiation with blue light (465 nm), complexes 1?3 can release bicalutamide and anticancer Ru(II) fragments, which possesses dual-action of AR binding and DNA interaction simultaneously. In vitro cytotoxicity study on these complexes further confirmed that complexes 1?3 exhibited considerable cytotoxicity upon irradiation with blue light. Significantly, complex 3 could be activated at 660 nm, which greatly increases the scope of complex 3 to treat deeper within tissue. Theoretical calculations showed that the lowest singlet excitation energy of complex 3 is lower than those of complexes 1?2, which explains the experimental results well. Moreover, the 3MC (metal centered) states of these complexes are more stable than their 3MLCT (metal to ligand charge transfer) states, indicating that the photoactive processes of these complexes are likely to result in ligand dissociation.

The synthesis and characterization of two new RuII complexes, a mononuclear complex [RuII(MeMPTP)(bpp)Cl]PF6 (1) and a dinuclear complex [RuII(MeMPTP)(bpp)RuII(bpy)2Cl](PF6)3 (2), [where MeMPTP = 4?-(4-methylmercaptophenyl)-2,2?:6?2??-terpyridine, bpp = 2,3-bis(2-pyridyl)pyrazine, bpy = 2,2?-bipyridine] is reported. Single-crystal X-ray structural determination of the compounds unambiguously confirms the formation of the complexes 1 and 2. Catalytic investigations of the complexes for the chemical oxidation of water in the presence of Ce4+ as a sacrificial oxidant reveals a higher rate of O2 evolution by the dinuclear complex 2 over the physical mixture of complex 1 and a redox mediator, [Ru(bpy)3]2+ (med), followed by the mononuclear complex 1. The enhancement in the catalytic rate of O2 evolution by 2 is ascribed to being due to the intramolecular redox process, which facilitates the facile formation of a high-valent ruthenium?oxo species that is required for water oxidation through a cooperative effect. The present study highlights the importance of the intramolecular redox process over the intermolecular redox process.

A series of mononuclear Ru trisbypiridine complexes connected to an anthraquinone unit by a flexible alkyl chain of varying lengths and a bolaamphiphilic dinuclear ruthenium complex bearing an anthraquinone unit in the middle of alkyl chain spacers were synthesized. Their conformational preference in CH3CN and in dihexadecyl phosphate vesicles was probed by utilizing the intramolecular electron-transfer quenching of the metal-to-ligand charge-transfer excited state of the Ru center by the appended quinone moiety. The length of the alkyl chain spacer had little effect on the quenching efficiency in either medium. A marked difference in the quenching behavior was observed only in the case of the dinuclear Ru complex in vesicles. These results indicate that the bolaamphiphilic structure is necessary and effective for the set of immobilized molecules to take a stretched conformation spanning a bilayer membrane.
