A new Ru(II) complex is described which serves as a luminescence lifetime-based sensor for fluoride and cyanide anions (KF = 640 000 mol-1, KCN = 430 000 mol-1). This chromophore displays observable changes in its UV-vis and steady-state luminescence spectra upon cyanide binding. Prior to cyanide addition, this complex exhibits a single-exponential lifetime (tau = 377 ± 20 ns). With increasing cyanide concentrations, the intensity decays are composed of two exponentials: long tau (320-370 ns) and short tau (13-17 ns). The average lifetimes shorten as a function of cyanide concentration since the fractional intensity shifts from an initial dominant long lifetime component to the short lifetime component. This work represents the first example of a direct method for the luminescence lifetime-based sensing of anions. Copyright

Near-infrared light can be used to manipulate the pH of aqueous solutions by using upconverting nanoparticle-assisted photocleavage of a ruthenium complex photobase. Upconverting nanoparticles and the photobase were also introduced into a pH-responsive hydrogel, in which near-infrared irradiation induced swelling of the hydrogel.

Two pyridine substituted beta-cyclodextrins have been synthesized and coordinated to the photoactive metal centres, [Ru(ii)(bpy)2] and [Re(i)(CO)3bpy], where bpy is 2,2?-bipyridyl. The photophysical and electrochemical properties of these model complexes have been examined and compared with dinuclear complexes formed when C60 was included between two cyclodextrin cavities of the metallocyclodextrin units. On inclusion of C60, significant quenching of the emission of the luminophores is observed. Concentration and laser power dependence confirm that this quenching is intramolecular. The quenching process is interpreted in terms of a photoinduced electron transfer between the photosensitizer and C60 centre on the basis of spectroscopic and electrochemical evidence. Rate constants of 1.3 ± 0.1 × 108 and 7.0 ± 0.4 × 107 s-1 have been determined for the Ru and Re based complexes, respectively. Significantly, these large rate constants indicate that that there is substantial electronic communication across the cyclodextrin at least for excited state processes.

Ruthenium complexes are very useful phosphorescent probes for the visualization of hypoxia. We designed and synthesized three ruthenium complexes possessing bromopyrene, naphthalene, or anthracene units to improve the oxygen response. These ruthenium complexes provided strong phosphorescence under hypoxic conditions, while an increase in oxygen concentration led to a decrease in phosphorescence intensity. Among the ruthenium complexes, that with a bromopyrene unit (Ru-BrPy) had the best properties. This showed good cellular uptake and bright emission in cells, and had the highest sensitivity for molecular oxygen. Thus, Ru-BrPy is a promising candidate as a molecular probe for detecting cellular hypoxia.

A new ruthenium(II) complex, [Ru(bpy)2(Htip)]Cl2 {where bpy = 2,2?-bipyridine and Htip = 2-(thiophen-2-yl)-1H-imidazo[4,5- f][1,10]phenanthroline}, has been synthesized and characterized by 1H NMR spectroscopy, elemental analysis, and mass spectrometry. The pH effects on UV-Vis absorption and emission spectra of the complex have been studied, and the ground- and excited-state acidity ionization constant values have been derived. The calf thymus (ct) DNA binding properties of the complex have been investigated with UV-Vis absorption and luminescence titrations, steady-state emission quenching by [Fe(CN)6]4-, DNA competitive binding with ethidium bromide, DNA melting experiments, and viscosity measurements. The molecular structures and electronic properties of [Ru(bpy)2(Htip)] 2+ and deprotonated form [Ru(bpy)2(tip)]+ have also been investigated by means of density functional theory calculations in an effort to understand the DNA binding properties. The results suggest that the complex undergo three-step successive protonation/deprotonation reactions with one of which occurring over physiological pH region, and act as a ct-DNA intercalator with an intrinsic DNA binding constant value on 105 M-1 order of magnitude that is insensitive to pH.

The first example of a binuclear ruthenium complex involving the p-carborane framework in the bridging ligand is reported. The bridging ligand is a symmetric linear array comprising a central p-carborane unit, two p-phenylene spacers, and two 5-yl-2,2?-bipyridine coordinating units. A homobinuclear RuII complex, with 2,2?-bipyridine as peripheral ligands, was synthesized and characterized. The RuII-RuIII mixed-valence species, obtained by partial oxidation, has been investigated with steady-state and time-resolved techniques in CH3CN. The rate of photoinduced electron transfer is 2.3 × 108 s-1.

Two new ligands designed to act as the core for metallostars based upon multiple bpy (bpy = 2,2′-obipyridine) metal-binding domains have been prepared. The first ligand 6 consists of a 1,3,5-triazine bearing three bpy metal-binding domains and was prepared inter alia using Stille methodology. All attempts to form complexes of 6 were unsuccessful. In contrast, a non-planar core compound based upon a tetraphenylmethane moiety bearing four bpy domains, also prepared using Stille couplings, was shown to form a tetraruthenametallostar complex containing four {Ru(bpy)3} motifs. Each of the {Ru(bpy)3} motifs is chiral, possessing Delta or Lambda chirality and detailed NMR studies indicate that the complex is formed with little or no diastereoselectivity leading to a mixture of diastereomers and a fuzzy stereochemistry.

A series of ruthenium (II) complexes of formulae trans-[Ru(PPh 3)2(L?H)2](ClO4)2 (1), [Ru(bpy)(L?H)2](ClO4)2 (2), [Ru(bpy)2(L?H)](ClO4)2 (3), cis-[Ru(DMSO)2(L?H)2]Cl2 (4), and [Ru(L?H)3](PF6)2 (5) (where L?H = 2-(2?-benzimidazolyl)pyridine) have been synthesized by reaction of the appropriate ruthenium precursor with 1,2-bis(2?-pyridylmethyleneimino) benzene (L). The complexes were characterized by elemental analyses, spectroscopic and electrochemical data. All the complexes were found to be diamagnetic and hence metal is in +2 oxidation state. The molecular structure of trans-[Ru(PPh3)2(L?H)2](ClO 4)2 has been determined by the single crystal X-ray diffraction studies. The molecular structure shows that Ru(II) is at the center of inversion of an octahedron with N4P2 coordination sphere. The ligand acts as a bidentate N,N?donor. The electronic spectra of the complexes display intense MLCT bands in the visible region. Cyclic voltammetric studies show quasi-reversible oxidative response at 0.99-1.32 V (vs Ag/AgCl reference electrode) due to Ru(III)/Ru(II) couple.
