Self-assembly of highly luminescent heteronuclear coordination cages

Exo-functionalized Pd2L4 cage compounds with attached Ru(ii) pyridine complexes were prepared via coordination-driven self-assembly. Unlike most of the previously reported palladium(ii) cages, one of these metallocages exhibits an exceptionally high quantum yield of 66%. The presented approach is promising to obtain luminescent coordination complexes for various applications.

Heteroditopic rhenium(I) and ruthenium(II) bipyridyl calix[4]arene receptors for binding cation-anion ion pairs

New heteroditopic ion pair receptors that contain rhenium(I) and ruthenium(II) bipyridyl amide anion recognition sites covalently linked to a lower rim calix[4]arene tetraester alkali metal cation binding site have been prepared and shown to bind alkali metal (Li+, Na+)-halide (Br-, I-) ion pair species. Proton NMR titration studies reveal the lower rim ester co-bound alkali metal cation significantly enhances the strength of bromide and iodide binding in acetonitrile solutions with the largest positive co-operative binding effect of sixtyfold observed with bromide and the lithium complex of one receptor. Solid/liquid extraction experiments show two of the receptors are capable of solubilising NaCl and NaOAc in dichloromethane solutions. The Royal Society of Chemistry 2001.

RuII Photosensitizer-Functionalized Two-Dimensional MoS2 for Light-Driven Hydrogen Evolution

Metallic-phase molybdenum disulfide (1T-MoS2) nanosheets have proven to be highly active in the hydrogen evolution reaction (HER). We describe construction of photosensitizer functionalized 1T-MoS2 by covalently tethering the molecular photosensitizer [RuII(bpy)3]2+ (bpy=2,2?-bipyridine) on 1T-MoS2 nanosheets. This was achieved by covalently tethering the bpy ligand to 1T-MoS2 nanosheets, and subsequent complexation with [RuII(bpy)2Cl2] to yield [RuII(bpy)3]?MoS2. The obtained [RuII(bpy)3]?MoS2 nanosheets were characterized using infra-red, electronic absorption, X-ray photoelectron, and Raman spectroscopies, X-ray powder diffraction and electron microscopy. The fabricated material exhibited a significant improvement of photocurrent and HER performance, demonstrating the potential of such two-dimensional [RuII(bpy)3]?MoS2 constructs in photosensitized HER.

Organometallic pi-tweezers, NCN pincers, and ferrocenes as molecular “Tinkertoys” in the synthesis of multiheterometallic transition-metal complexes

This review describes the synthesis, reaction chemistry, structures, and bonding of early-late heterodi-, heterotri-, and heterotetrametallic transition-metal complexes by applying the molecular “Tinkertoy” approach. As connecting units between the different metal atoms, pi-conjugated carbon-rich organic and/or inorganic groups can be used. The electrochemical behavior of such one-dimensional molecular wire molecules, coordination polymers, starlike structures, and dendritic oriented transition-metal species, respectively, is presented as well.

Development of a ruthenium multi-pyridine complex as photosensitizer for highly efficient light driven water oxidation

As we all know, the photosensitizer is the vital role in photocatalytic water oxidation system. In this paper, a novel [Ru(bpy)2(tpphz)](PF6)2 complex (PS1) was synthesized and characterized fully. And, it displayed a higher photoactivity (TON, 110) than [Ru(bpy)3](PF6)2 (PS2) (TON, 62) and [Ru(bpy)2(dcb)](PF6)2 (PS3) (TON, 82) for water oxidation in a three-component system with Ru(bda)(isoq)2 as catalyst. The main reason for the enhancement of photocatalytic activity should be that the pi-pi stacking supramolecular interaction between the pi-tpphz ligand of the PS1 and the pi-isoq ligand of the catalyst increased the intermolecular interaction between PS1 and catalyst, and promoted the molecular aggregation and accelerated valid electronic transmission. Nevertheless, a modest driving force of PS1 for photocatalysis water oxidation should be another contribution.

Turning on red and near-infrared phosphorescence in octahedral complexes with metalated quinones

We report the synthesis of pi-bonded ruthenium, rhodium, and iridium o-benzoquinones [Cp*M(o-C6H4O2)] n [M = Ru (2), n = 1-; Rh (3), n = 0; Ir (4), n = 0] following a novel synthetic procedure. Compounds 2-4 were fully characterized by spectroscopic methods and used as chelating organometallic linkers, “OM-linkers”, toward luminophore bricks such as Ru(bpy) 22+, Rh(ppy)2+, and Ir(ppy) 2+ (bpy = 2,2?-bipyridine; ppy = 2-phenylpyridine) for the design of a novel family of octahedral bimetallic complexes of the general formula [(L-L)2M(OM-linkers)][X]m (X = counteranion; m = 0, 1, 2) whose luminescent properties depend on the choice of the OM-linker and the luminophore brick. Thus, dinuclear assemblies such as [(bpy)2Ru(2)][OTf] (5-OTf), [(bpy)2Ru(2)][Delta- TRISPHAT] (5-DeltaT) {TRISPHAT = tris[tetrachlorobenzene-1,2-bis(olato)] phosphate}, [(bpy)2Ru(3)][OTf]2 (6-OTf), [(bpy) 2Ru(4)][OTf]2 (7-OTf), [(bpy)2Ru(4)][Delta- TRISPHAT]2 (7-DeltaT), [(ppy)2Rh(2)] (8), [(ppy) 2Rh(3)][OTf] (9-OTf), [(ppy)2Rh(4)][OTf] (10-OTf), [(ppy)2Rh(4)][Delta-TRISPHAT] (10-DeltaT), [(ppy) 2Ir(2)] (11), [(ppy)2Ir(3)][OTf] (12-OTf), [(ppy) 2Ir(4)][OTf] (13-OTf), and [(ppy)2Ir(4)][Delta-TRISPHAT] (13-DeltaT) were prepared and fully characterized. The X-ray molecular structures of three of them, i.e., 5-OTf, 8, and 11, were determined. The structures displayed a main feature: for instance, the two oxygen centers of the OM-linker [Cp*Ru(o-C6H4O2)]- (2) chelate the octahedral chromophore metal center, whether it be ruthenium, rhodium, or iridium. Further, the carbocycle of the OM-linker 2 adopts a eta4-quinone form but with some catecholate contribution due to metal coordination. All of these binuclear assemblies showed a wide absorption window that tailed into the near-IR (NIR) region, in particular in the case of the binuclear ruthenium complex 5-OTf with the anionic OM-linker 2. The latter feature is no doubt related to the effect of the OM-linker, which lights up the luminescence in these homo- and heterobinuclear compounds, while no effect has been observed on the UV-visible and emission properties because of the counteranion, whether it be triflate (OTf) or Delta-TRISPHAT. At low temperature, all of these compounds become luminescent; remarkably, the o-quinonoid linkers [Cp*M(o-C6H4O2)] n (2-4) turn on red and NIR phosphorescence in the binuclear octahedral species 5-7. This trend was even more observable when the ruthenium OM-linker 2 was employed. These assemblies hold promise as NIR luminescent materials, in contrast to those made from organic 1,2-dioxolene ligands that conversely are not emissive.

New luminescent probe for the selective detection of dopamine based on in situ prepared Ru(II) complex-sodium dodecyl benzyl sulfonate assembly

Due to clinical importance, detection of dopamine by using easy and rapid method is still ongoing challenge. Here we present a simple and quite efficient method for dopamine (DA) detection in alkalescent medium using in situ prepared Ru(II) complex and sodium dodecyl benzyl sulfonate (SDBS) as highly luminescent luminophore. The luminescence enhancement in the Ru(II) complex (Ru-CIP) has been observed in the miceller medium formed by SDBS. The capability to successively quench the luminescence intensity has been tested for variety of molecules and only dopamine as analyte found to be able to quench luminescence effectively. Hence selective quenching of luminescence by dopamine was used as a tool to detect dopamine and two linear concentration ranges has been established from 0.1 muM to 1muM and from 2 muM to 10 muM with limit of detection (LOD) is 6.6 nM (S/N = 3). Spectral evidence showed that luminescence quenching mechanism arose via Forster resonance energy transfer (FRET) among oxidized DA (i.e. DA quinone) and in situ generated Ru-CIP and SDBS assembly. Due to ultra sensitivity and high selectivity of the prescribed (Ru-CIP-SDBS) luminescent probe has a strong potential for practical analytical application in clinical diagnosis.

Synthesis, characterization, redox behavior, DNA and protein binding and antibacterial activity studies of ruthenium(II) complexes of bidentate schiff bases

Two new ruthenium(II) complexes of Schiff base ligands (L) derived from cinnamaldehyde and ethylenediamine formulated as [Ru(L)(bpy)2](ClO4)2, where L1 = N,N?-bis(4-nitrocinnamald-ehyde)ethylenediamine and L2 = N,N?-bis(2-nitrocinnamaldehyde)-ethylenediamine for complex 1 and 2, respectively, were isolated in pure form. The complexes were characterized by physicochemical and spectroscopic methods. The electrochemical behavior of the complexes showed the Ru(III)/Ru(II) couple at different potentials with quasi-reversible voltammograms. The interaction of the complexes with calf thymus DNA (CT-DNA) using absorption, emission spectral studies and electrochemical techniques have been used to determine the binding constant, Kb and the linear Stern?Volmer quenching constant, KSV. The results indicate that the ruthenium(II) complexes interact with CT-DNA strongly in a groove binding mode. The interactions of bovine serum albumin (BSA) with the complexes were also investigated with the help of absorption and fluorescence spectroscopy tools. Absorption spectroscopy proved the formation of a ground state BSA-[Ru(L)(bpy)2](ClO4)2 complex. The antibacterial study showed that the Ru(II) complexes (1 and 2) have better activity than the standard antibiotics but weak activity than the ligands.

Ruthenium and rhenium complexes with silyl-substituted bipyridyl ligands

The preparation of 5,5?-bis(trimethylsilyl)- (1a) and 5,5?-bis(pentamethyldisilanyl)-2,2?-bipyridines (1b) by dehalogenative coupling of the corresponding 2-bromo-5-silylpyridines is described. Silyl substitution causes broad and red shifted pi ? pi* and sigma ? pi* UV-vis absorption bands; electrochemical reduction is facilitated. With these ligands, a series of ruthenium complexes [Ru(bpy)2(L)](PF6)2 (3a, L = 1a; 3b, L = 1b) and [RuL3](PF6)2 (4a, L = 1a; 4b, L = 1b), as well as rhenium compounds Re (L)(CO)3Cl (5a, L = 1a; 5b, L = 1b) (bpy = 2,2?-bipyridine) were synthesized. These complexes give rise to red-shifted metal-to-lig-and charge-transfer absorptions in the region of 460-480 nm for the ruthenium complexes and around 400 nm for the rhenium complexes. While the oxidation potentials of ruthenium complexes 3a, 3b, 4a, and 4b are almost the same as that of [Ru(bpy)3](PF6)2, reduction of the ruthenium and rhenium complexes occurs at more positive potentials than that of [Ru(bpy)3](PF6)2 and Re(bpy)(CO)3Cl. Band maxima of the metal-to-ligand charge-transfer emission of the ruthenium and the rhenium complexes were observed at 620 and 610 nm, respectively. The results indicate that the LUMO levels of 2,2?-bipyridine and its metal complexes are lowered by electron-accepting effects of trimethylsilyl and pentamethyldisilanyl substituents, while the HOMO level of bpy is elevated by pentamethyldisilanyl substitution due to the effective sigma-pi conjugation between an Si-Si bonding orbital and a bpy pi orbital.
