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.

The dinuclear complex [(eta6-C6H6)Ru(mu-N3)Cl]2 (1) is obtained by the reaction of [(eta6-C6H6)RuCl2]2 with sodium azide in ethanol. 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.

Novel heterogenized asymmetric catalysts were synthesized by immobilizing preformed Ru catalysts on magnetite nanoparticles via the phosphonate functionality and were characterized by a variety of techniques, including TEM, magnetization, and XRD. These nanoparticle-supported chiral catalysts were used for enantioselective heterogeneous asymmetric hydrogenation of aromatic ketones with very high enantiomeric excess values of up to 98.0%. The immobilized catalysts were easily recycled by magnetic decantation and reused for up to 14 times without loss of activity and enantioselectivity. Orthogonal nature of the present catalyst immobilization approach should allow the design of other superparamagnetic nanoparticle-supported asymmetric catalysts for a wide range of organic transformations.

Three ruthenium complexes containing a bidentate piq ligand, [(piq)Ru(bpy)2]2+ (1), [(piq)Ru(phen)2]2+ (2), and [(piq)Ru(DIP)2]2+ (3) (piq = phenylisoquinolinate, bpy = 2,2?-bipyridine, phen = 1,10-phenanthroline, DIP = 4,7-diphenyl-1,10-phenanthroline), were prepared. The DNA binding properties of complexes 1?3 to double-stranded DNA were studied. The binding of 1?3 to calf-thymus DNA (ct-DNA) yielded lower emission intensities than those observed with the corresponding Ru complexes alone. To explore potential interactions of complexes 1?3 with lipid-rich organs in live cells, the emission properties of the Ru probes were studied with liposomes. The emission intensities of complexes 1?3 were enhanced to similar extents upon interaction with liposomes. The cytotoxic activities of the complexes against MDA-MB-231 and HUVECs were evaluated in vitro. The effects of complexes 1?3 on the survival of MDA-MB-231 cells were examined and compared with that of cis-platin. Complexes 2 and 3 were more cytotoxic to cancer cells than cis-platin. Complexes 1?3 showed cellular uptakes of 1.1, 10.6, and 76.6%, respectively, indicating that the greatest amount of complex 3 entered the cancer cells. Inhibition of cell migration by complexes 1?3 was also evaluated by the wound healing assay.

Reactions of pyrazole based ligand and halide bridged arene d6 metal precursors resulted a series of mono and di-substituted pyrazole based half sandwich d6 metal complexes. In general, they are formulated as [(arene)MLCl2] [M = Ru, arene = benzene (1), p-cymene (2), arene = Cp*, M = Rh (3) and Ir (4)] and [(arene)ML2Cl] [M = Ru, arene = benzene (5), p-cymene (6), arene = Cp*, M = Rh (7) and Ir (8)]. All these complexes were characterized by various spectroscopic techniques (IR, 1H NMR, ESI-MS, and UV/Vis). The molecular structures were confirmed by single-crystal X-ray diffraction technique. Spectroscopic studies revealed that complexation i.e., mono- and di-substitution occurred by the ratio-based reaction between pyrazole ligand and metal precursor through the neutral nitrogen rather than protic nitrogen. In these complexes deprotonation of the protic nitrogen does not occur unlike the other complexes containing pyrazole derivatives, in which the pyrazole ligand is anionic.

A tripodal tris(urea) ligand with 2,2?-bipyridyl (bpy) substituents (L) has been designed and synthesized, which coordinates with three equivalents of Ru(bpy)2Cl2·2H2O, followed by treatment with NH4PF6, to afford the anion receptor [(bpy)6Ru3L](PF6)6 (1). The anion-binding behavior of the ligand L and the RuII-bpy functionalized receptor 1 toward different anions was investigated by 1H NMR (for L and 1), fluorescence, and UV-vis spectroscopy (for 1). Both compounds showed selective recognition of SO42- or H2PO4- ions in the 1:1 binding mode in the NMR studies. The RuII complex 1 displayed the metal-to-ligand charge transfer emission at 600 nm, which was quenched on addition of the sulfate and dihydrogen phosphate ions. Quantitative fluorescence titration experiments were carried out and the stability constants (log K) of the complex 1 with SO 42- and H2PO4- ions were obtained to be 4.73 and 4.69 M-1 (1:1 binding mode), respectively.
