Conjugation at the oligonucleotide level based on isoxazole phosphoramidites generated by click chemistry
(2011)
Freeman, Colin; Ni Cheallaigh, Aisling; Heaney, Frances
Abstract:
The versatility of the isoxazole generating nitrile oxide–alkyne Huisgen cycloaddition for provision of chemically modified oligonucleotides has been extended; in a novel approach isoxazole conjugated oligodeoxyribonucleotides have been constructed by phosphoramidite chemistry of isoxazole derivatives previously generated by nitrile oxide–alkyne click chemistry. The conjugation involves manual solid phase synthesis at room temperature in aqueous ethanol and proceeds in high yield.

Ethyl 2-{[2-(3-nitrophenyl)-5-phenyl-1H-imidazol-4-yl]sulfanyl}acetate: synthesis via a microwave-mediated combinatorial chemistry approach
(2002)
Gallagher, John F.; Coleman, Claire M.; O'Shea, Donal F.
Abstract:
The orange title compound, C₁₉H₁₇N₃O₄S, can be synthesized either via microwave-mediated combinatorial chemistry strategies or conventional synthetic procedures. The phenyl and meta-nitrophenyl C₆ rings are essentially coplanar with the central imidazolyl ring, with interplanar angles of 0.87 (5) and 0.97 (4)°, respectively, resulting in optimum conjugation (SCH₂ moiety included); [lambda]max = 281 nm in CH₃CN. The principal intermolecular interactions are Nimid-H...Onitro and Nimid-H...O=C [N...O = 3.058 (2) and 3.432 (3) Å, and N-H...O = 128 and 153°, respectively]. The closest H...S distance is an intramolecular C-H...S contact, with H...S = 2.54 Å and C-H...S = 136°.

A click chemistry route to 2-functionalised PEGylated and cationic beta-cyclodextrins: co-formulation opportunities for siRNA delivery
(2012)
O'Mahony, Aoife M.; Ogier, Julien R.; Desgranges, Stephane; Cryan, John F.; Darcy, Raphael; O'Driscoll, Caitríona M.
Abstract:
A new approach to the synthesis of amphiphilic beta-cyclodextrins has used 'click' chemistry to selectively modify the secondary 2-hydroxyl group. The resulting extended polar groups can be either polycationic or neutral PEGylated groups and these two amphiphile classes are compatible in dual cyclodextrin formulations for delivery of siRNA. When used alone with an siRNA, a cationic cyclodextrin was shown to have good transfection properties in cell culture. Co-formulation with a PEGylated cyclodextrin altered the physicochemical properties of nanoparticles formed with siRNA. Improved particle properties included lower surface charges and reduced tendency to aggregate. However, as expected, the transfection efficiency of the cationic vector was lowered by co-formulation with the PEGylated cyclodextrin, requiring future surface modification of particles with targeting ligands for effective siRNA delivery.

The complex synthesis and solid state chemistry of ceria-lanthana solid solutions prepared via a hexamethylenetetramine precipitation.
(2011)
HOLMES, JUSTIN DEREK
Abstract:
Mixed oxide solid solutions are becoming ever more commercially important across a range of applications. However, their synthesis can be problematical. Here, we show that ceria-lanthana solid solutions can be readily prepared via simple precipitation using hexamethylenetetramine. However, the solution chemistry can be complex which results in the precipitated particles having a complex structure and morphology. Great care must be taken in both the synthesis and characterisation to quantify the complexity of the product. Even very high heat treatments were not able to produce highly homogeneous materials and x-ray diffractions reveals the non-equilibrium form of particles prepared in this way. Unexpected crystal structures are revealed including a new metastable cubic La2O3 phase.

Abstract:
The Chemistry-Aerosol Mediterranean Experiment (ChArMEx; http://charmex.lsce.ipsl.fr) is a collaborative research program federating international activities to investigate Mediterranean regional chemistry-climate interactions. A special observing period (SOP-1a) including intensive airborne measurements was performed in the framework of the Aerosol Direct Radiative Impact on the regional climate in the MEDiterranean region (ADRIMED) project during the Mediterranean dry season over the western and central Mediterranean basins, with a focus on aerosol-radiation measurements and their modeling. The SOP-1a took place from 11 June to 5 July 2013. Airborne measurements were made by both the ATR-42 and F-20 French research aircraft operated from Sardinia (Italy) and instrumented for in situ and remote-sensing measurements, respectively, and by sounding and drifting balloons, launched in Minorca. The experimental setup also involved several ground-based measurement sites on islands includi...

Azadipyrromethenes: from traditional dye chemistry to leading edge applications.
(2016)
Ge, Yuan; O'Shea, Donal F
Abstract:
<p>This article is also available at <a href="http://pubs.rsc.org/en/content/articlelanding/2016/cs/c6cs00200e#!divAbstract">http://pubs.rsc.org/en/content/articlelanding/2016/cs/c6cs00200e#!divAbstract</a></p>
<p>Azadipyrromethenes were first described over 70 years ago as blue pigments, but now are rapidly emerging as a compound class with highly desirable near infrared photophysical properties. Since the turn of the century several routes to azadipyrromethenes have been developed and numerous post-synthesis derivatizations have allowed for their exploitation in both biological and material sciences. The relative ease of access to specifically designed derivatives is now allowing their use in multiple technological formats from real-time fluorescence imaging, to solar energy materials, to optoelectronic devices and many more. In this review we have highlighted the synthetic component of this story as it is the ability to generate the des...

The chemistry and photochemistry of Ru(II) bipyridyl carbonyl complexes incorporated in Nafion
(1991)
Jermyn, Adrienne
Abstract:
THESIS 2556
The chemical reactions of bis(bpy)carbonylruthenium complexes, catalysts for the water gas shift reaction, have been investigated under mild conditions in Nafion, an ionic polymer. Chemical and photochemical reactions performed under alkaline, aqueous or atmospheric conditions were of particular interest. A variety of techniques have been used to investigate the reactions occurring. These include Infra-red and Ultra-violet spectroscopy. The Nafion matrix is ideally suited to these techniques for bis(bpy)carbonylcomplexes because of the absence of absorption bands in the UV/V is spectrum and the carbonyl region of the IR spectrum. It is also chemically inert. It is possible to prepare and incorporate the complexes into Nation. Reactions are confined within an inert matrix and therefore the species involved in the water gas shift reaction catalysed by [Ru(bpy)2(CO)CI]+ have been formed in-situ and subsequently characterised by spectroscopic methods.

Abstract:
THESIS 11406
The ability to directly and selectively functionalise hydrocarbons is one of the greatest remaining challenges facing chemists. The development of catalytic systems capable of affecting these transformations under ambient conditions would be of great environmental and economic importance. In nature, enzymes have been shown to utilise metal-based oxidants, such as high-valent terminal metal-oxos (M=O) to carry out these reactions. A multitude of biomimetic Mn=O and Fe=O complexes have been reported which are capable of activating C-H bonds. In this thesis, we postulate that late transition metal-oxos (Co, Ni, Cu, Zn) will form more potent oxidants than their early transition metal counterparts. However, there are currently no examples of stable late transition metal-oxo species in the literature, owing to the concept of the oxo-wall. It has been postulated that the oxo-wall may be circumvented through the synthesis of pseudo-tetrahedral metal-oxos. Herein, we describ...

Computational studies of lithium complexes and alkanes
(2001)
Hayes, Joseph Martin
Abstract:
THESIS 6356
This thesis studies via computation "non-standard" aspects of the chemistry of two different systems; lithium complexes and alkanes. Various approaches to modelling of these species is investigated: classical forcefield, semiempirical and ab initio methods. A program is developed (PAROPT) for extraction of forcefield parameters from ab initio energies, forces, or a combination of energies and forces. Our studies of lithium complexes focus on synthetically important lithium amide type bases such as lithium diisopropylamide (LDA), but we propose that the success/failures of the modelling approaches observed are generally valid for lithium chemistry.

Mimicking ribonucleotide reductases: Biomimetic manganese complexes and their reaction with superoxide
(2019)
MAGHERUSAN, ADRIANA MARIA
Abstract:
An important discovery in class Ib ribonucleotide reductase?s chemistry has been the identification of a MnII2 active site, that required a superoxide anion (O2??), rather than dioxygen (O2), to access a high-valent MnII2 oxidant. Many synthetic mononuclear Mn model complexes have been prepared to mimic the structures and reactivity of Mn-metalloenzymes. However, the reactivity of a MnII2 model complex with O2?? has never been investigated and this was the main objective of this thesis. The main topics of the work described in this thesis are the study of O2?? reactivity of MnII2 complexes, preparation and characterisation of intermediates, to mimic the active postulated intermediates observed in class Ib Mn2 RNRs. In chapter 2, we describe our initial discovery that complex [MnII2(O2CCH3)(N-Et-HPTB)](ClO4)2 (1) could be reacted with O2?? at low temperature (?-40 ?C), to form the metastable [MnIIMnIII(O2)(O2CCH3)(N-Et-HPTB)]+ (2). This species was characterised by electronic absorpt...

Abstract:
THESIS 8297
Part 1 describes the synthetic route and the characterisation of a family of nitrogen heterosuperbenzene compounds. Those polyaromatic ligands, which contain a fused dipyrimidine unit possess unusual photophysical properties and are ideal for transition metal coordination. The novel homoleptic Ru(II) complexes and their photophysical properties are presented.

Solution-state Anion Binding Studies of Urea- and Amide-based Hydrogen-bonding Receptors for the Design of Supramolecular Assemblies
(2019)
GILLEN, DERMOT
Abstract:
This work investigates urea- and amide-based hydrogen-binding systems as small-molecule anion-binding receptors, as part of a project in the Gunnlaugsson group to develop complex molecular assemblies built around the urea?anion interaction. Chapter 1 introduces the concepts of anion binding, templating and directing, and discusses the utility of molecular assemblies, interlocked structures and urea-based anion-binding receptors, specifically in the context of recent advancements in supramolecular chemistry. An overview of anionreceptor clusters is provided, with a focus on helicates and barrels. In Chapter 2, the anion binding behaviour of a series of novel electron-rich derivatives of the meta-phenylene bis(phenylurea) motif is analysed in detail through 1 H NMR titrations with the tetrabutylammonium salts of a range of anions. The meta-phenylene bis(phenylurea) motif is shown to bind anions such as dihydrogenphosphate, benzoate and acetate in 1:2 host?guest stoichiometries. No el...

Abstract:
THESIS 9181
Transparent conducting oxides (TCOs) are a unique class of materials which combine the normally mutually exclusive properties of transparency and conduction. Despite the many applications and widespread interest in TCO materials, there are a number of unanswered questions regarding the electronic structure and defect chemistry of TCO materials, in particular with regard to p-type TCOs. The main motivation for the work presented in this thesis has been to fully understand the complex chemistry of the Cu I-based delafossite oxides, and to ascertain if high performance p-type TCOs can be produced from these materials.

Abstract:
General experimental Analytical TLC was performed on precoated (250 μm) silica gel 60 F-254 plates from Merck. All plates were visualized by UV irradiation, and/or staining with 5% H2SO4 in ethanol followed by heating. Flash chromatography grade silica gel 60 (230-400 mesh) was obtained from Merck. Mass analysis was performed on an Ettan MALDI-TOF Pro from Amersham Biosciences or LASER-TOF LT3 from Scientific Analytical Instruments with 3- hydroxypicolinic acid or 2,’ 4’, 6’-trihydroxyacetophenone as matrix. The NMR spectra were obtained at 1H (300 MHz), 13C (75 MHz) and 31P (121 MHz) on a Bruker instrument at 25 ºC. Chemical shifts are reported in ppm downfield from TMS as standard. HPLC was carried out using a Gilson instrument equipped with a UV detector and a Nucleosil C18 column (4.0 × 250 mm) or Phenomenex Clarity. Fluorescence spectra were recorded on a Varian Cary Eclipse instrument. All other chemical agents were purchased from Aldrich Chemical Company unless otherwise noted.

Abstract:
Mercury ion complexation reactions were carried out between 3 and various mercury(II) salts. 1H NMR studies showed that the role of solvent, the anion chosen and the initial reaction conditions were critical and that the formation of a “simple” mercury(II) complex was non-trivial. The mercury(II) ion can cause either (i) the formation of an ion-pair system, which have a characteristic doubling of all signals in the 1H NMR spectrum, (ii) a cleavage reaction to occur resulting in the reformation of the calix[4]arene diester compound 2, but only when the reaction is heated and (iii) “simple” mercury binding to the pyridine rings when the binding studies are carried out using NMR titration techniques. The electrochemistry results, on the same systems, show that the initial reaction involves the removal of the phenoxide protons followed by the resulting catalysis of the mercury species. This proton removal is not observed in the NMR spectra of any of the mercury reactions. It was also fo...

Abstract:
With an ever demanding job market and indu stry complaints of grade inflation in the university sector, o ur graduates need m ore t han jus t good grades to obtain su ccess ful employment. They need to be a b l e to demonstrate a wide variety of skills such as problem solving, team work and the ability to work on t h eir own initia tive. This paper discusses a new type of chemistry practical that tries to incorporate all of these skills in to a n engaging undergraduate la b oratory entitled “Mystery Death on a River”. Chemistry undergraduate labs a t present o f ten follow the cookbook recipe appro a ch where students follow a distin ct recipe wi th help from a de mon strator. While these type s of laboratories provide the students with valuable skills, they inhibit th e student’s ability to understand or pr o vide insight in to what they are a ctually d o i n g throughout the practical (Beussman 2007).

The development of hybrid antigene therapeutics using nucleic acid click chemistry

Abstract:
Given their ability to break single- and double-strand DNA with high selectivity, the design of restriction endonuclease mimics has become an area of considerable research interest. One class of mimetics are copper artificial metallo-nucleases (AMNs) that prompt direct strand scission by oxidatively damaging duplex DNA. Therefore, the formation of metal-catalysed free radicals in the vicinity of nucleic acids provides a viable route to developing artificial gene editing tools. The aim of this research was to develop new copper-based AMNs for selective knockdown of the green fluorescent protein (GFP) gene. To achieve this, a novel pool of gene-targeted biomaterials was developed by hybridising intercalating azide-modified phenanthrene AMNs to triplex formation oligonucleotides (TFOs) using copper-catalysed alkyne-azide cycloaddition (CuAAC) ‘click’ chemistry. Upon isolating the family of AMN-TFO hybrids, the project focused on their triplex formation and stabilisation properties. In ...

Abstract:
Chemically resistant parts for flow chemistry, with integrated mixing elements have been produced using the 3D printing process of fused filament fabrication, from poly(etheretherketone). Poly(etheretherketone) has greater chemical resistance than common fused filament fabrication materials such as acrylonitrile butadiene styrene, polypropylene, or even high-performance plastics like poly(etherimide), in addition to having superior thermal resistance and excellent mechanical strength. Printed reactors were demonstrated to be suitable for liquid–liquid extraction and flow chemistry and to be capable of withstanding pressures of at least 30 bar allowing superheated solvents to be used. Burst tests in simple geometries of 20 minute duration have indicated that increased operating pressures of up to 60 bar could be accommodated in future reactor designs. The ability to use fused filament fabrication for these reactors allows highly customisable, cost effective flow reactors and equipmen...

Abstract:
Self-assembly has proven to be a powerful tool for the construction of complex superstructures. The assembly of monomers into supramolecular architectures via non-covalent interactions is chiefly directed by the molecular structures, their functional groups, and environmental conditions. The principal advantage of non-covalent interactions is reversibility, which allows the assembly of monomers into supramolecular structures in situ depending on the local conditions. In addition, the supramolecular approach provides a degree of control over self-assembly at the molecular level, thereby influencing the macroscopic level and facilitating tuning of the bulk material properties. This review discusses the meritorious examples of supramolecular materials constructed through the molecular assembly process, guided by the classical principles of supramolecular chemistry. Furthermore, this year (2017) marks the 50th anniversary of supramolecular chemistry in honor of the first example of supr...
