Resumo:

A novel ruthenium(II) polypyridyl complex bearing 1,8-naphthyridine was successfully designed and synthesized. This complex was fully characterized by EI-HRMS, NMR, and elemental analyses. The recognition properties of the complex for various metal ions were investigated. The results suggested that the complex displayed high selectivity and sensitivity for Cu2+ and Fe3+ ions with good anti-interference in the CH3CN/H2O (1:1, v/v) solution. The fluorescent chemosensor showed obvious fluorescence quenching when the Cu2+ and Fe3+ ions were added. The detection limits of Cu2+ and Fe3+ were 39.9 nmol/L and 6.68 nmol/L, respectively. This study suggested that this Ru(II) polypyridyl complex can be used as a high selectivity and sensitivity fluorescent chemosensor for Cu2+ and Fe3+ ions.

This thesis reports the spectroscopic and computational studies of a number of Cu(I), Re(I) and Ru(II) complexes of polypyridyl ligands. The ligands considered in this study were 1,10-phenanthroline, 4,7-diphenyl-1,10-phenanthroline, 3,4,7,8-tetramethyl-1,10-phenanthroline, dibenzo[b,j][1,10]phenanthroline, dipyrido[2,3-a:3�,2�-c]phenazine, dipyrido[2,3-a:3�,2�-c]-6,7-dichlorophenazine and dipyrido[2,3-a:3�,2�-c]-6,7-dimethylphenazine. Density functional theory calculations were carried out on the polypyridyl ligands. Validation of the calculations was carried out by comparison of the predicted values to observables. The structures were compared to previously published X-ray crystal data. Calculated bond lengths were typically calculated to be within 0.02 Å of those in the crystal structure. The calculated vibrational spectra were compared to measured IR and Raman spectra. The correspondence between calculated and measured frequencies was quantified using the mean absolute deviation between the two sets of frequencies. This was typically found to be less than 10 cm⁻�. The robustness of the calculation was further tested by calculations on perdeuterated analogues of some of the ligands. The calculations were extended to metal moieties and validated as for the ligands. Resonance Raman and infrared spectra of the reduced states of some Re(I) complexes are reported. The structure and spectra have been modelled by considering the radical anion of the polypyridyl ligand and the reduced state of the complex. There is improvement in the mean absolute deviation, between calculated and observed frequencies, upon incorporation of the metal moiety into the calculation. Spectra are successfully modelled confirming the validity of the modelled structures. The resonance Raman and infrared spectra of the metal-to-ligand charge transfer excited states of some Cu(I), Re(I) and Ru(II) complexes are reported. Density functional theory calculations on the lowest energy triplet states aided in the spectral assignment of bands. Cu(I) complexes were successfully modelled with mean absolute deviations, between calculated and observed frequencies, of less than 10 cm⁻�. The spectra of the Re(I) and Ru(II) complexes were less successfully modelled. Incorporation of the Ru(II) centre into the calculation of the vibrational frequencies of dipyrido[2,3-a:3�,2�-c]phenazine complexes offers no improvement over modelling the radical anion of this polypyridyl ligand. The excited state lifetimes of a number of polypyridyl complexes have been reported. The changes in lifetimes of similar complexes were found to be consistent with the energy gap law or changes in the conjugation of the involved polypyridyl ligand. This project has allowed the excited state structures of a number of polypyridyl complexes to be determined using vibrational spectroscopy to validate density functional theory calculations. This has provided a study strategy that may be applied to other metal polypyridyl complexes.

Resumo:

Application of chemotherapeutic agents in current cancer treatment has been limited by adverse effects as poor selectivity results in systemic toxicity; most chemotherapy approaches also experience inherited or acquired drug resistance which lead to reduced treatment outcome. Research efforts have focused on the discovery of novel chemotherapies that overcome the limitations mentioned above. Ru(II) polypyridyl complexes with anti-cancer properties have been extensively studied as traditional cytotoxic agents and photodynamic therapy agents due to their photophysical and photochemical characteristics. Most research has focused on the design of Ru(II) polypyridyl complexes that have affinities to nucleic acids as inspired by the classic small molecule metal complex cisplatin. Though modifying the structures of ligands on the ruthenium metal center, the hydrophilicity, charge state and photochemical properties can be tuned, resulting to Ru(II) polypyridyl complexes that act through cellular targets other than DNA. Understanding the mechanism of action and identifying functional targets remain the challenging and complex research topic in the design and study of novel medication or candidates. With the development of semi-high throughput cytological profiling in a bacterial system, rapid investigation of the mechanism of action can be achieved to distinguish anti-cancer agents which possess different mechanisms of actions. Ru(II) polypyridyl complexes with different scaffolds have been studied and suggested to have anti-cancer properties through DNA damage response, and/or translational inhibition.

A series of alkynylplatinum(II) polypyridine complexes with 4,4′,4′′-tricarboxy-2,2′:6′,2′′-terpyridine and 4,4′-dicarboxy-2,2′-bipyridine as TiO2 anchoring functionalities, has been successfully synthesized. Their photophysical, electrochemical and luminescence properties have been extensively studied. The excited state properties were probed using nanosecond transient absorption spectroscopy. [Pt(tctpy)(C≡C-Th-BTD-Th)][NnBu4]2 displayed a long-lived transient signal which was tentatively assigned to result from the formation of a charge-separated state, which could be alternatively described as a [Pt(tctpy)???(C≡C-Th-BTD-Th)+?] state, with the charge recombination rate constant determined to be 2.9 × 105 s?1. The excited state redox potentials for the oxidation process were determined and the data confirmed the ability of the complexes to inject an electron into the conduction band of TiO2. The majority of the complexes were found to sensitize the nanocrystalline TiO2 and exhibit photovoltaic properties, which have been characterized by current-voltage measurements under illumination of air mass (AM) 1.5G sunlight (100 mW cm–2). A new class of molecular dyads comprising metalloporphyrin-linked alkynylplatinum(II) polypyridine complexes was synthesized and characterized. Their photophysical, electrochemical and luminescence properties have been studied in detail. The excited state properties were probed using nanosecond transient absorption spectroscopy which indicated the formation of a charge-separated state involving the porphyrin radical anion, [Por??－(C≡C)Pt+?]. The excited state redox potentials for the oxidation process were also determined with the data supporting the capability of the complexes to inject an electron into the conduction band of TiO2. The majority of the complexes were found to sensitize the nanocrystalline TiO2 and exhibit photovoltaic properties, as characterized by current-voltage measurements under illumination of air mass (AM) 1.5G sunlight (100 mW cm–2). A series of organic materials consisting of a triphenylamine-based donor with oligothiophene or oligothienylenevinylene based-conjugated linker and dicyanovinyl, tricyanovinyl or cyanacrylic acid groups as acceptor, was synthesized and characterized. Their photophysical, electrochemical, thermal and luminescence properties were studied. Transient absorption spectra of TPA-OTV-DCN in dichloromethane solution on the pico- to nanosecond timescale were recorded after femtosecond laser excitation at 400 nm. A transient signal at ca. 700 nm was tentatively assigned to result from the formation of a charge-separated [(TPA-OTV)+??DCN??] state with the charge recombination rate constant determined to be 5.3 × 109 s?1. The energy levels of the LUMOs of TPA-OTV1-DCN, TPA-OTV2-DCN, TPA-OTV3-DCN TPA-TAZ1-DCN, TPA-TAZ2-DCN and TPA-o-4Th-DCN were calculated to be of ca. ?3.9 eV, establishing the formation of a downhill driving force for the energetically favorable electron transfer process involving the injection of an electron into the LUMO of the C60 acceptor. The majority of the compounds were found to exhibit photovoltaic properties. The photovoltaic responses were characterized by current-voltage measurements under illumination of air mass (AM) 1.5G sunlight (100 mW cm–2).

Measurement and mapping of the pressure distribution across the surface of a suitably scaled model is an integral step in the design of any aircraft or automobile. For this purpose, the traditional workhorses of the aeronautic and automotive industries have been pressure taps--small orifices that contain electronic pressure transducers. Unfortunately, in addition to the limited spatial resolution achievable with such devices, their technical complexity and cost constitute serious disadvantages. For more than 35 years, researchers have pursued a fundamentally different alternative: indirect measurement of pressure via oxygen-induced quenching of the luminescence emitted by certain chemical species. Porphyrin complexes of dipositive palladium and especially platinum have emerged as one of the principal classes of oxygen-sensitive luminophores; ruthenium(II) polypyridyl complexes comprise another. Various other metals also form luminescent coordination complexes that are susceptible to quenching by O2, however, and these too have contributed to the diversity of luminophores that are now available for incorporation into pressure-sensitive paints and related films and coatings. After treating the photophysics of luminescence quenching by molecular oxygen and quantitative descriptions of this phenomenon in the ideal case and in heterogeneous media, the thesis presents a comprehensive survey of the chemical literature on oxygen-sensitive luminophores. Efforts to prepare and characterize a novel porphyrin-pillared mixed zirconium phosphonate are then detailed. Following complexation of Pt(II) ions by the porphyrin moieties, this material is expected to display oxygen-sensitive luminescence and should ameliorate such difficulties as luminophore aggregation and matrix photodegradation that are associated with many existing pressure-responsive coatings. Its preparation necessitated preliminary formation of a porphyrin functionalized with two phenylphosphonic acid groups, which was obtained by synthesizing dipyrromethane and diethyl 4-formylphenylphosphonate and condensing these two precursors. The mixed phosphonate, a layered material assembled from ZrOCl2 · 8H2O, methylphosphonic acid, and the aforementioned porphyrin, was then prepared in refluxing HF. Solid-state 31P NMR spectra and powder X-ray diffraction patterns were acquired for the final product, its estimated interlayer spacing of 22.8 Å figuring prominently in analysis and discussion of the X-ray data.

A series of Fe2+ spin crossover (SCO) complexes [Fe(5/6)]2+ employing hexadentate ligands (5/6) with cis/trans-1,2-diamino cyclohexanes (4) as central building blocks were synthesised. The ligands were obtained by reductive amination of 4 with 2,2′-bipyridyl-6-carbaldehyde or 1,10-phenanthroline-2-carbaldehyde 3. The chelating effect and the rigid structure of the ligands 5/6 lead to exceptionally robust Fe2+ and Zn2+ complexes conserving their structure even in coordinating solvents like dmso at high temperatures. Their solution behavior was investigated using variable temperature (VT) 1H NMR spectroscopy and VT Vis spectroscopy. SCO behavior was found for all Fe2+ complexes in this series centred around and far above room temperature. For the first time we have demonstrated that the thermodynamics as well as kinetics for SCO can be deduced by using VT 1H NMR spectroscopy. An alternative scheme using a linear correction term C1 to model chemical shifts for Fe2+ SCO complexes is presented. The rate constant for the SCO of [Fe(rac-trans-5)]2+ obtained by VT 1H NMR was validated by Laser Flash Photolysis (LFP), with excellent agreement (1/(kHL + kLH) = 33.7/35.8 ns for NMR/LFP). The solvent dependence of the transition temperature T1/2 and the solvatochromism of complex [Fe(rac-trans-5)]2+ were ascribed to hydrogen bond formation of the secondary amine to the solvent. Enantiomerically pure complexes can be prepared starting with R,R- or S,S-1,2-diaminocyclohexane (R,R-trans-4 or S,S-trans-4). The high robustness of the complexes reduces a possible ligand scrambling and allows preparation of quasiracemic crystals of [Zn(R,R-5)][Fe(S,S-5)](ClO4)4·(CH3CN) composed of a 1 : 1 mixture of the Zn and Fe complexes with inverse chirality

Ruthenium (II) polypyridine complexes in general have been extensively studied because of their unique redox and photochemical properties. A typical example of such complexes is tris(2,2’-bipyridyl) ruthenium (II). In this study, this complex was synthesized and then characterized using electronic spectroscopy and cyclic voltammetry. It was also shown that the ruthenium concentration could be accurately determined using ICP-MS. It was found that the complex is very stable in various chemical environments. It was observed from spectrophotometric investigations that persulphate and lead dioxide easily oxidize Ru(bpy)3 2+ to Ru(bpy)3 3+ in the presence of heat and H2SO4, respectively. It was also observed that the oxidation between Ru(bpy)3 2+ and cerium (IV) occurred at approximately 3:2 [Ce(IV)]/[Ru(II)] mole ratio. The resultant Ru(bpy)3 3+ solution was unstable in the presence of light and recovery of Ru(bpy)3 2+ occurred gradually. The regeneration of Ru(bpy)3 2+ from Ru(bpy)3 3+ was found to be a multistep process, which appears to involve the formation of an intermediate species. The following reaction model was found to best explain the kinetic data obtained: Ru(bpy)3 2+ + Ce(IV) → Ru(bpy)3 3+ Ru(bpy)3 3+ → Ru(bpy)3 2+ Ru(bpy)3 3+ → Ru* intermediate Ru* intermediate → Ru(bpy)3 2+ Theoretical rate constants were also calculated for the same process under the experimental conditions. The comparison between the experimental and theoretical results gave good agreement. In addition, the factors that influence the rate of the regeneration of Ru(bpy)3 2+ from Ru(bpy)3 3+ were also discussed.

Metallopolymers, a combination of organic polymers and metal center, contain metal atoms in repeating monomers can change its dynamic and thermodynamic properties through the directionality of coordination bonds and chemical tailoring of ligands. In the past decade, self-assembled functional supramolecular metallopolymers have aroused a surge of research interest, and have demonstrated application potential in cancer therapy. In this chapter, we have summarized the progress in the rational design of biological application of different metallopolymers. Especially, a copper polypyridyl complex was found be able to self-assemble into a supramolecular metallopolymer driven by the intermolecular interactions, which could enhance the uptake in cancer cells through endocytosis, thus effectively inhibit tumor growth in vivo without damage to the major organs. This study may provide a good example to use self-assembled metallopolymer to achieve enhanced anticancer efficacy.

Polypyridyl ruthenium(II) complexes have been widely researched as promising functional molecules. We have found unique photoisomerization reactions of polypyridyl ruthenium(II) aquo complexes. Recently we have attempted to provide insight into the mechanism of the photoisomerization of the complexes and distinguish between the distal−/proximal-isomers in their physicochemical properties and functions. Moreover, polypyridyl ruthenium(II) aquo complexes have been intensively studied as active water oxidation catalysts (WOCs) which are indispensable for artificial photosynthesis. The catalytic aspect and mechanism of water oxidation by the distal-/proximal-isomers of polypyridyl ruthenium(II) aquo complexes have been investigated to provide the guided thought to develop more efficient molecular catalysts for water oxidation. The recent progress on the photoisomerization and water oxidation of polypyridyl ruthenium(II) aquo complexes in our group are reviewed to understand the properties and functions of ruthenium complexes.

Biorelevant metal ions such as Cu2+ and Fe2+/Fe3+ participate in various biological events which include electron transfer reactions, delivery and uptake of oxygen, DNA and RNA syntheses, and enzymatic catalysis to maintain fundamental physiological processes in living organisms. So far, several analytical techniques have been investigated for their precise detection; however, luminescence-based sensing is often superior due to its high sensitivity, selectivity, fast and easy operation and convenient cellular imaging. Owing to their immense photophysical and photochemical properties stemming from large Stokes shift, absorption in visible region, good photostability and long excited state lifetimes, Ru(II)-polypyridyl-based complexes have gained increasing interest as luminophores. Over past few decades, several Ru(II)-polypyridyl based chemosensors have rapidly been developed for detection of different biorelevant and other metal ions. The main object of this book chapter is to cover a majority of Ru(II)-polypyridyl based chemosensors showing a selective and sensitive detection of bio-relevant Cu2+ and Fe2+/Fe3+ ions. The photophysical properties of Ru(II) complexes, detection of metal ions, sensing mechanism and applications of these sensors are discussed at a length.
