Five 3,5-difluorophenyl-substituted ruthenium complexes [Ru(bpy)2(dfpbpy)(ClO4)2] (Ru-Fbpy-bpy; bpy=bipyridine, dfpbpy=5,5?-di(3,5-difluorophenyl)-2,2?-bipyridine), [Ru(dpp)2(dfpbpy)(ClO4)2] (Ru-Fbpy-dpp; dpp=4,7-diphenyl-1,10-phenanthroline), [Ru(dpp)2(dfpphen)(ClO4)2] (Ru-Fphen-dpp; dfpphen=5,5?-di(3,5-difluorophenyl)-1,10-phenanthroline), [Ru(dpp)2(4,7-dfpphen)(ClO4)2] (Ru-Fdpp-dpp; 4,7-dfpphen=4,7-di(3,5-difluorophenyl)-1,10-phenanthroline), and [Ru(4,7-dfpphen)3(AsF6)2] (Ru-Fdpp) were synthesized, and their photophysical, electrochemical, and electroluminescent properties were studied systematically. The introduction of the electron-withdrawing group 3,5-difluorophenyl leads to a redshift of the emission of the ruthenium complexes. In addition, the 3,5-difluorophenyl substituent extends the pi conjugation of the ligand, and thus facilitates the metal-to-ligand charge-transfer process of the complexes. All the complexes display orange-red phosphorescent emissions centered at 638, 638, 624, 614, and 605 nm, respectively. Density functional theory calculations show that the lowest unoccupied molecular orbital of Ru-Fbpy-dpp, Ru-Fphen-dpp, and Ru-Fdpp-dpp are all distributed on the 3,5-difluorophenyl-substituted ligand. By using these complexes as emitters, highly luminescent single-layer devices are obtained. The optimized device based on Ru-Fdpp exhibits the highest luminous efficiency and power efficiency of 4.19 cd A-1 and 1.46 lm W-1, respectively. Bright ideas: Five 3,5-difluorophenyl-substituted ruthenium complexes have been synthesized and characterized. The photoluminescent efficiencies of the complexes improved after introduction of an electron-withdrawing substituent (see scheme). The complexes are suitable as dopant light-emitting materials for organic light-emitting diodes.

Efficacy of the ferrocene appended piano-stool dipyrrinato complexes [(eta6-C6H6)RuCl(fcdpm)] (1), [(eta6 – C10H14)RuCl(fcdpm)] (2), [(eta6-C12H18)RuCl(fcdpm)] (3) [(eta5-C5Me5)RhCl(fcdpm)] (4) and [(eta5-C5Me5) IrCl(fcdpm)] (5) [fcdpm = 5-ferrocenyldipyrromethene]toward anticancer activity have been described. Binding of the complexes with calf thymus DNA (CT-DNA) and BSA (bovine serum albumin) have been thoroughly investigated by UV-Vis and fluorescence spectroscopy. Binding constants for 1-5 (range, 104-105 M-1) validated their efficient binding with CT-DNA Molecular docking studies revealed interaction through minor groove of the DNA, on the other hand these also interact through hydrophobic residues of the protein, particularly cavity in the subdomain IIA. In vitro anticancer activity have been scrutinized by MTT assay, acridine orange/ethidium bromide (AO/EtBr) fluorescence staining, and DNA ladder (fragmentation) assay against Dalton’s Lymphoma (DL) cells. Present study revealed that rhodium complex (4) is more effective relative to ruthenium (1-3) and iridium (5) complexes.

The synthesis, linear optical and nonlinear optical properties, as well as the electrochemical behavior of a series of proligands containing the 4-(4-N,N-dimethylaminostyryl)-1-methyl pyridinium (DASP+) group as a push-pull moiety covalently linked to terpyridine or bipyridine as chelating ligands are reported in this full paper. The corresponding multifunctional RuII and ZnII complexes were prepared and investigated. The structural, electronic, and optical properties of the pro-ligands and the ruthenium complexes were investigated using density functional theory (DFT) and time-dependent (TD) DFT calculations. A fairly good agreement was observed between the experimental and the calculated electronic spectra of the pro-ligands and their corresponding ruthenium complexes. A quenching of luminescence was evidenced in all ruthenium complexes compared with the free pro-ligands but even the terpyridinefunctionalized metal complexes exhibited detectable luminescence at room temperature. Second order nonlinear optical (NLO) measurements were performed by Harmonic Light Scattering and the contribution of the DASP+ moieties (and their relative ordering) and the metal-polypyridyl core need to be considered to explain the nonlinear optical properties of the metal complexes.

A series of ruthenium(II) arene complexes (arene = p-cymene, hexamethylbenzene and benzene) containing dibenzoylmethane ligand (DBMH) of formula [(arene)Ru(DBM)Cl] and their ionic derivatives bearing PTA (1,3,5-triaza-7-phosphaadamantane), of formula [(arene)Ru(DBM)(PTA)]X (X = PF6- or SO3CF3-) have been synthesized and fully characterized. The solid-state structures of five complexes have been determined by single-crystal X-ray diffraction. These ruthenium materials exhibit intense photoluminescence emission at room temperature in the solid state. All complexes effectively bind to calf thymus DNA through intercalative/electrostatic interactions with more affinity for DNA minor groove. Finally, the antitumor activity of both ligand and complexes was evaluated against the U266 and RPMI human multiple myeloma cell lines, and some of them showed a cytotoxic and pro-apoptotic effect toward both cell lines.

A strategy based on a ring-closing metathesis (RCM) reaction of pyridinium azadienes in the presence of the second generation Grubbs catalyst was employed as a new approach to synthesize the 1-azaquinolizinium (pyrido[1,2-a]pyrimidin-5-ium) heterocycle and some simple derivatives. This method was also successfully applied to the first reported synthesis of the benzo-1-azaquinolizinium (pyrimido[2,1-a]isoquinolinium) cation by using the Hoveyda-Grubbs catalyst in Cl2CHCHCl2 at 130 C.

Concise and high-yielding total syntheses of amphidinolides T1, T3, and T4 have been completed using an alkynyl macrolactone as a common late-stage intermediate. The required alpha-hydroxy ketone motif was installed by sequential alkyne hydrosilylation, epoxidation, and Fleming-Tamao oxidation. An oxonium ylide rearrangement formed the trisubstituted tetrahydrofuran core found in the natural products.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, you can also check out more blogs about246047-72-3

The benzene ruthenium beta-diketonato complexes of the general formula [(eta6-C6H6)Ru(L?L)Cl] {L?L = O,O?-acac (2); O,O?-bzac (3); O,O?-dbzm (4)} are obtained in methanol by the reaction of [(eta6-C6H6)RuCl2]2 with the corresponding beta-diketonates. These complexes further react with sodium azide in ethanol to yield complexes of the type [(eta6-C6H6)Ru(L?L)N3] [L?L = O,O?-acac (5); L?L = O,O?-bzac (6); L?L = O,O?-dbzm (7)]. The complexes 5-7 are obtained as well by treating 1 with sodium salts of beta-diketonates. These neutral benzene ruthenium azido complexes undergo [3+2] dipolar cycloaddition reaction with activated alkynes (MeO2CC{triple bond, long}CCO2Me, EtO2CC{triple bond, long}CCO2Et) or fumaronitrile (NCHC{double bond, long}CHCN) to yield the corresponding benzene ruthenium triazolato complexes; [(eta6-C6H6)Ru(O,O?-acac){N3C2(CO2Me)2}] (8), [(eta6-C6H6)Ru(O,O?-acac){N3C2(CO2Et)2}] (9), [(eta6-C6H6)Ru(O,O?-acac){N3C2HCN}] (10), [(eta6-C6H6)Ru(O,O?-bzac){N3C2HCN}] (11) and [(eta6-C6H6)Ru(O,O?-dbzm){N3C2HCN}] (12). These complexes are fully characterized on the basis of microanalyses, FT-IR and FT-NMR spectroscopy. The molecular structure of [(eta6-C6H6)Ru(O,O?- acac){N3C2(CO2C2H5)2}] (9) is confirmed by single crystal X-ray diffraction study.
