▼ Short-lived organic and organometallic species produced photochemically using a UV laser or UV lamp were studied by using NMR spectroscopy.The compounds studied included photochromic compounds, cyclic ketenimines, indole compounds and s-alkane complexes.A new method of laser alignment was tested in this project for directing laser light into an NMR tube. A photochromic molecule was used as the reacting compound. This photochromic molecules switches rapidly between a merocyanine form in the presence of strong UV light, back to a spirooxizine form without UV irradiation. By observing the composition of the solution via NMR spectroscopy, the laser can be aligned by maximizing the amount of merocyanine form. However, this molecule only reverts rapidly when the light induced changes occur around room temperature. Thus, the application of this method is limited to around room temperature.Phenyl azide and 3,5-dimethoxyphenyl azide were photolyzed in different solvents with the aim of observing a didehydroazepine reactive intermediate. Unfortunately, no intermediate was directly observed.The photolysis of 4,6-dimethoxy-1,2-diphenyl indole, was also studied in this thesis. This indole sample can be photo reacted with singlet O2 in solution and it is expected to form short lived peroxide and oxetane intermediates. The indole compound was photolyzed in different solvents at low temperature in the presence of a sensitizer and oxygen, but no intermediates were observed.An organometallic compound, (hexaethylbenzene)tungstentricarbonyl has been shown previously to generate short lived s-alkane complexes when photolyzed in alkane solvents. This tungsten compound was previously found to have a selective binding of methyl groups when forming tungsten alkane complexes. In this work, the tungsten compound was photolyzed in methylcyclopentane at low temperature. By analysing the 2D 1H NMR spectra, the product composition was found to be a mixture of two tungsten(methylcyclopentane) complexes with the tungsten bound either to the methylene groups which are the furthest from the methyl group ( methylene groups on the C-3) or bound to the methyl group. The binding ratio to the C-3 methylene groups and methyl group was 5.8:1. Advisors/Committee Members: Ball, Graham, Chemistry, Faculty of Science, UNSW.

▼ The presence of trace organic compounds (TOrCs) in wastewater effluent and surface waters has raised attention due to their health and environmental effects. Some TOrCs are naturally attenuated via biodegradation, photo-degradation and/or adsorption, but some persist in the environment as contaminants in surface and ground waters. Thus, it is crucially important to understand their transformation pathways and their mechanisms following their discharge into the environment. This work presents research in three parts: • The first part represents an investigation of photo-transformation of TOrCs (e.g., furfuryl alcohol, p-cresol, gemfibrozil) under UV254, UVA and natural sunlight, and involving reactive oxygen species including singlet oxygen, hydroxyl radicals, triplet excited states, and specific inorganic radicals that are created by effluent organic matter (EfOM). Singlet oxygen was the only ROS, generated from effluent organic matter (EfOM) that mainly contributed to the photo-transformation of these selected TOrCs. A comprehensive mechanism and complementary kinetic model were proposed to predict the trajectories of TOrC removals via reaction with singlet oxygen. Simulations built on predicted quantum efficiencies accounted for light shading and competitive effects. Agreement between measurements and simulations was excellent. • The second part of the dissertation summarizes expected removal efficiencies for fifty-five TOrCs in alternative engineered and natural treatment processes including conventional biological treatment, advanced oxidation processes (AOP), reverse osmosis (RO), granular activated carbon (GAC), and sunlight photolysis. • The last section of the dissertation follows the trajectories of a series of TOrCs and total estrogenic activity in the Santa Cruz River, following their discharge from a wastewater treatment plant in the Tucson area. The study suggests that some TOrCs tend to persist in the environment while others experience photo (or other) transformations that diminish their concentrations or activities with distance and time of travel in the river. The attenuation of estrogenic activity was dependent on sunlight and the presence of specific (unidentified) wastewater components. Advisors/Committee Members: Arnold, Robert G (advisor), Sáez, A.

Os produtos farmacêuticos têm sido considerados como um problema ambiental devido à sua entrada contínua e persistência no ecossistema aquático, mesmo em baixas concentrações (µg L-1 e ng L-1). Muitos fármacos têm sido frequentemente determinados em Estações de Tratamento de Esgoto (ETEs), águas superficiais, subterrâneas e de abastecimento, devido à baixa eficiência dos sistemas convencionais de tratamento na eliminação destes compostos. O diclofenaco (DCF), é um Anti-Inflamatório Não Esteróide (AINE) comumente utilizado como analgésico, antiartrítico e antirreumático. Possui uma baixa biodegradabilidade e tem a capacidade de bioacumulação nos tecidos de seres vivos, podendo apresentar efeitos ecotóxicos. Como o DCF pode não ser eficientemente removido pelos tratamentos convencionais de água e esgoto, novos processos têm sido pesquisados para a sua remoção, entre eles os processos oxidativos avançados (POAs). O objetivo deste trabalho foi tratar o DCF sódico aquoso por fotocatálise heterogênea (TiO2/UV). Para isso foi realizado um planejamento fatorial 25 com a finalidade de se determinar os efeitos dos parâmetros reacionais – dosagem e tipo de fotocatalisador, concentração inicial do fármaco, tipo de aceptor de elétrons e pH – sobre o desempenho do tratamento. A variável-resposta observada foi a redução da área sob o espectro de absorção no UV. A condição ótima de tratamento foi: pH = 5; dosagem de TiO2 = 0,5 g L-1; concentração inicial de DCF = 20 mg L-1; aceptor de elétrons = oxigênio; e tipo de catalisador = P25 (Evonik). No estudo da cinética, a degradação do fármaco foi acompanhada por Cromatografia Líquida de Alta Eficiência (CLAE). Para a amostra tratada por fotocatálise heterogênea, a concentração de DCF foi reduzida a aproximadamente 40 µg L-1 em 30 min de irradiação e a degradação seguiu o modelo cinético de Langmuir-Hinshelwood (R2 = 0,95) com constante de velocidade k = (2,3 ± 0,070) × 103 µg L-1 min-1 e uma constante de adsorção K = (2,1 ± 0,17) × 10-4 L µg-1. No ensaio de fotólise a concentração foi reduzida a aproximadamente 70 µg L-1 em 12,5 min de tratamento e observou-se uma cinética de ordem zero (R2 = 0,96) com k = (2,7 ± 0,070) × 103 µg L-1 min-1. Foram identificados alguns intermediários de oxidação por cromatografia líquida acoplada a espectroscopia de massas (LC/MS-MS) e foram realizados ensaios ecotoxicológicos (Daphnia similis e Lactuca sativa) das amostras tratadas. Nenhum dos tratamentos (fotocatálise e fotólise) estudados gerou ecotoxidade nos organismos-teste. Indica-se a fotólise, nas condições deste trabalho, como mais eficiente para a degradação do diclofenaco.

Pharmaceuticals are considered an environmental problem due to their continuous input and persistence in aquatic ecosystems, even at low concentrations (µg L-1 e ng L-1). Many drugs are often detected in Sewage Treatment Plants (STPs), surface water, groundwater and drinking water due to the low efficiency of conventional treatment systems…

▼ Neonicotinoid insecticides are currently the most widely used class of insecticides worldwide, accounting for 25% of total insecticide use. They are registered in 120 countries for use on more than 140 crops. Concern has grown, however, over their widespread detection in global surface waters, soil, finished drinking water, and wastewater, and for their potential role in colony collapse disorder in honey bees. This work set out to examine hydrolysis and photolysis reaction rates of neonicotinoids, as well as to identify reaction products and determine the toxicity of the reaction products on mosquitoes. Hydrolysis rates were tested between pH 4 and pH 10. Reaction rates were pseudo-first order and highly pH dependent. Calculated half-lives ranged from >1000 days to 10 days. Divalent metal ions (Cu2+, Ni2+, Zn2+) and minerals (kaolinite, goethite, TiO2) were found to have little to no effect on neonicotinoid hydrolysis. Experiments from pH 4 to pH 10 revealed a non-elementary rate law for neonicotinoid degradation, with the hydroxide concentration being raised to a power of 0.55 ± 0.09. Nitenpyram, imidacloprid, thiamethoxam, and clothianidin were found to undergo direct photolysis, with quantum yields of 0.025 ± 0.001, 0.0119 ± 0.0001, 0.0167 ± 0.0002, and 0.0133 ± 0.0001, respectively. Acetamiprid degraded very slowly via direct photolysis, but was found to undergo indirect photolysis due to reaction with OH∙ with a bimolecular rate constant of 1.7 ± 0.2×109 M-1 s-1. Reaction products were identified for all reactions, with the urea derivative as the most commonly detected product. Toxicity experiments on mosquitoes indicate no residual toxicity from hydrolysis or photolysis products, which may be expected given the removal of the pharmacophore during reactions. While abiotic reaction products were found to be non-toxic, results from experimental work indicates long environmental half-lives for the tested neonicotinoids, which may help to explain their observed persistence in environmental matrices.

▼ A clean energy driven economy requires renewable production of zero-emission fuels, such as hydrogen (H2). Photocatalytic generation of H2 is one such method to fulfill this demand. Photocatalytic water splitting is an electrochemical process driven by solar energy to produce H2. Although there have been many investigations on photocatalytic water splitting, the number of concepts utilizing visible light is limited. In the present study, H2 evolution from water splitting is demonstrated using the novel concept of nanowire-;nanoparticle (NW-NP) conjugate devices irradiated by visible light. Photolytic nanodevice suspensions are fabricated via sol-;gel synthesis of vanadium oxyhydrate (V3O7�H2O) NWs, followed by solution chemistry with HAuCl4 for reduction of gold (Au) NPs on the NW surfaces. Characterization of nanodevices was performed via TEM, SEM, and optical spectroscopy. Products of photolysis were quantified and analyzed by Gas Chromatography (GC). The performance of the nanowire-;nanoparticle conjugate devices was compared with previous photolytic device designs by the use of quantum and internal conversion efficiencies (QE and ICE, respectively). The present thesis demonstrates photocatalytic production of H2 using V3O7�H2O NW -; Au NP conjugate devices under 470 nm excitation. The "photolytic nanodevice suspension in water" concept poses the potential for scalable H2 production, in addition to the provision for a low-;cost technique due to fabrication by sol-;gel synthesis and solution chemistry. The V3O7�H2O aerogel, a recently discovered semiconductor material, is found to be a suitable photoanode due to its narrow band gap energy of 2.18 eV, and its stability during photolysis. The diameters of the V3O7�H2O NWs are found to be 12 nm (�2.4 nm) from SEM images. The decoration of NWs with Au NPs is verified by TEM imaging and Au NPs are estimated to be 7.5 nm (�2.2 nm) in size. After decoration of NWs by Au NPs, a near-;field enhancement effect on optical absorption by NWs was observed by UV-visible spectroscopy. Further, the emergence of new optical absorbance peaks indicates possible coupling of incident light into waveguide modes of the NWs. QE and ICE values for the NW-NP conjugate devices are found to be 19.28% and 8.98%, respectively, for the first hour of photolysis. Advisors/Committee Members: Kalkan, A.

▼ Due to their potential health impact on human beings and ecosystems, persistent trace organic compounds (TOrCs) have aroused concern from both the public and professionals. In particular, the discharge of pharmaceuticals, endocrine disrupters, disinfection byproducts and other TOrCs from wastewater treatment plants into the environment is an area of extensive current research. This work studies the fate and treatments of TOrCs, with emphases on advanced oxidation processes (AOPs). This work presents predicted removal efficiencies of a variety of engineered and natural processes for 55 frequently encountered TOrCs in treated wastewater, based on previously reported data and using existing predictive models. Correlations between physicochemical and biological properties of TOrCs and treatment performance were explored. Removal of TOrCs in all processes investigated in this study was found to be sensitive to matrix effects. Heuristic guidelines for selection of sequenced treatment processes for TOrCs management were established. A field reconnaissance of natural process of TOrCs was conducted by analyzing the occurrence and fate of a suite of TOrCs, as well as estrogenic activity in water and sediments in the Santa Cruz River, an effluent-dependent stream in Tucson, Arizona. Some TOrCs, including contributors to estrogenic activity, were rapidly attenuated with distance of travel in the river. TOrCs that have low biodegradability and low octanolwater partitioning coefficients were less removed. Results of independent experiments indicated potential indirect photodegradation of estrogenic compound by reactive species generated from photolysis of effluent organic matter. Utilizing advanced oxidation processes (AOPs) as tertiary water and wastewater treatment is an option to prevent discharge of TOrCs into the environment. Compared to conventional AOPs, the ability of generating hydroxyl radicals (•OH) without additional doses of hydrogen peroxide (H2O2) or ozone makes ultraviolet (UV) photolysis of ferric hydroxo complexes a novel AOP, especially in acidic environments. A Fe(III)/UV254 kinetic model, which combines Fenton-like mechanism, and photolyses of Fe3+, FeOH2+ and H2O2 was proposed and experimentally validated to predict Fenton-like and H2O2 direct UV254 photolysis scenarios, individually. Nevertheless, the model underestimated the ferrous ion development during Fe(III)/UV254 photolysis, perhaps due to the overprediction of the oxidation of Fe2+ by •OH. The UV/H2O2 AOP was also studied in this work. A predictive kinetic model was developed to evaluate process efficiency of oxidation of p-cresol by UV/H2O2 photolysis based on a complete reaction mechanism, including reactions of intermediates with •OH. Results of this study highlight the significance of consideration of radical scavenging effects by the byproducts from oxidation of organic matter in model prediction performance.

▼ Triclosan (TCS; 5-chloro-2-(2,4-dichlorophenoxy)phenol) and triclocarban (TCC; 3,4,4’-trichlorocarbanilide) are two antimicrobials ubiquitously found in surface waters. Many studies exist for the photolysis and toxicity of TCS, but not for TCC. Both compounds undergo photolysis, and are commonly found simultaneously in surface waters, yet effects of mixtures of these compounds to aquatic organisms are unknown. The aims of these projects are to determine the relative toxicities of TCS, TCC, and their photolysis products, all with and without dissolved organic matter (DOM), and determine the structure of any TCC photoproducts deemed important due to toxicity. The effects of mixtures of these parent compounds and photoproducts will be studied.Acute toxicities were tested using Daphnia magna in 96-hr LC50 assays for TCS, TCC, and photolyzed compounds with and without DOM in moderately hard EPA water. DOM has no impact on the toxicity of TCS (LC50 of 1.62µM (95% confidence interval (CI) 0.920-2.864) without DOM, 1.76 µM (95% CI 1.174-2.652) with DOM). TCS was significantly detoxified after photolysis (LC50s of 8.48µM (95% CI 6.681-10.77) without DOM, 8.51µM (95% CI 2.700-26.84) with DOM). The toxicity of TCC was not affected by DOM (LC50 of 0.087µM (95% CI 0.040-0.191) without DOM, LC50 of 0.147 µM (95% CI 0.050-0.434) with DOM), and TCC photolyzed in EPA water alone was significantly detoxified (LC50 of 2.67µM, 95% CI 2.067-3.443). When TCC was photolyzed with DOM the toxicity of the photoproducts did not decrease (LC50 of 0.032µM, 95% CI 0.017-0.060), indicating that DOM mediates the transformation of TCC to toxic photoproducts. Using this data, binary mixture concentrations were calculated to assess effects of these compounds and photoproducts simultaneously versus their individual effects. LC50s were the basis for toxic units (TUs), with a mixture of ½ the LC50 of one compound and ½ the LC50 of another compound representing one TU, or LC50, at which 50% mortality would be expected with additive toxicity. Mixture tests were conducted the same as single chemical tests, using a range of TUs to estimate 96-h TU50s. TU50s indicated the type of interaction between D. magna and multiple compounds versus effects of a single compound. Interactions among the compounds/photoproducts were synergistic or additive, with TU50s ranging from 0.025 to 1.45. During initial photolysis experiments differences in photolysis rates of TCS were observed in EPA vs. Milli-Q waters. To assess the reasons for these differences, kinetics of TCS photolysis were determined for waters containing single constituents of EPA water. Results indicated that bicarbonate in EPA water enhanced direct photolysis of TCS (kobs of 0.7109/min vs 0.0382/min, respectively) at pHs below its pKa. Effects of pH and bicarbonate concentration on TCS photolysis rates were tested. Results indicated bicarbonate has more influence on photolysis at higher concentrations and pHs below TCS’ pKa. To assess the role of deprotonation on TCS photolysis, methyl-triclosan (MeTCS), a… Advisors/Committee Members: Lanno, Roman (Advisor), Chin, Yu-Ping (Advisor).

Im Rahmen dieser Promotionsarbeit wurden Fragestellungen der troposphärischen Ozonproduktion, des photostationären Gleichgewicht des NO2-NO-O3-ROx-Systems, des Einflusses von heterogenen Reaktionen an Mineralstauboberflächen und der Bedeutung lokaler anthropogener Emissionen für Spurengasmessungen an einem Gebirgsobservatorium untersucht. Dazu wurde insbesondere ein atmosphärenchemisch-meteorologischer Datensatz ausgewertet, welcher während der Feldmesskampagne MINATROC II im Juli/August 2002 am Global Atmosphere Watch (GAW) Observatorium Izana (2360m über NN) auf Teneriffa gewonnen wurde. Der Datensatz enthält Messdaten von Aerosolen, Spurengasen, Strahlungsgrößen und meteorologischen Parametern. Eine dichte Sahara-Staubwolke passierte die Messstation zwischen dem 28. und 31.07.2002. Die Mischungsverhältnisse von O3, H2O2, NOx und ROx zeigten während dieses Ereignisses Abnahmen zwischen 10% und 50%. Insbesondere infolge der Reduktion von NO und HO2 wurde eine deutliche Verringerung der Netto-Ozon-Produktion in der Staubwolke berechnet. Die Bewertung der verschiedenen Terme der Ozonproduktion bzw. –vernichtung zeigte relativ geringe Beiträge der einzelnen photochemischen Verlustreaktionen am Ozonbudget. Im Rahmen einer Boxmodellstudie, welche die Eingangsdaten von MINATROC II verwendete, wurde ein Vergleich zwischen Simulation und Messung kurzlebiger Spurengase angestellt. Die Modellrechnungen weisen darauf hin, dass die reduzierten H2O2-Mischungsverhältnisse in der Sahara-Staubwolke unter Berücksichtigung heterogener Reaktionen von HO2 bzw. H2O2 an Stauboberflächen erklärt werden können. Die Betrachtungen zum photostationären Gleichgewicht des NO2-NO-O3-ROx-Systems ergeben hauptsächlich stark überhöhte Leighton-Verhältnisse. Die Abweichungen der Messdaten vom photostationären Gleichgewichtszustand sind dabei zum Verschmutzungsgrad der Atmosphäre antikorreliert. Eine Reihe potentieller Einflüsse auf das NO2-NO-O3-ROx-System wurde diskutiert, wobei gezeigt werden konnte, dass das bisherige Betrachtungsmodell nicht ausreicht, um die beobachteten Abweichungen vom photostationären Gleichgewicht zu erklären. Während für die Nachtmessungen von MINATROC II Bedingungen der freien Troposphäre vorlagen, waren die Messungen am Tage von der Kopplung zwischen photochemischer Aktivität und thermisch getriebener Hangströmung betroffen. Die zum Messort gelangte anthropogen beeinflusste Grenzschichtluft konnte dabei auf maximalen Mischungsanteilen zwischen 15% und 85% quantifiziert werden. Abschließend wurden verschiedene Aspekte der Quellen und der Verteilung anthropogener Verschmutzungen auf Teneriffa im Zusammenhang der zuvor behandelten Fragen diskutiert.

Within this doctoral thesis, several questions of tropospheric ozone production, photostationary state of the NO2-NO-O3-ROx system, influence of heterogeneous reactions at mineral dust surfaces, and the influence of local anthropogenic emissions on trace gas measurements at a mountain observatory have been investigated. An atmospheric-chemical and meteorological dataset,…

▼ Treatment wetlands are becoming an increasing popular approach for nutrient removal from municipal wastewater effluent due to their low cost and energy requirements, as well as the ancillary benefits they provide. Recently, they have also been considered as a means of removing wastewater-derived trace organic contaminants. Initial studies of the removal of trace organic contaminants in treatment wetlands indicate that removal is often insignificant and is highly variable among systems. Efforts to improve wetland treatment efficiency have been hampered by a limited understanding of trace organic contaminant removal mechanisms. In this research, a novel type of wetland, consisting of a shallow cell lined with geotextile fabric to prevent the growth of emergent macrophytes, is considered for the removal of wastewater-derived trace organic contaminants and nutrients. When combined with other types of wetland cells in a unit process fashion (i.e., wetland cells designed to remove specific contaminants are arranged in series), open-water unit process wetlands may provide a basis for using treatment wetlands to remove a wide range of trace organic contaminants from municipal wastewater effluent.To understand how open-water treatment wetlands could be integrated with other types of wetland cells in unit process wetlands, the treatment wetland literature was critically reviewed (Chapter 2). Removal mechanisms of trace organic contaminants and pathogens in treatment wetlands were considered, including sorption, biotransformation, photolysis, sedimentation, predation, and photoinactivation. Methods of enhancing these mechanisms in unit process wetland cells were also identified, both in commonly employed vegetated cells and through the development of novel wetland configurations, such as open-water cells. To further optimize unit process wetlands, the arrangement of wetland cells was evaluated. The application of the unit process concept to a wide range of wastewater contaminants has the potential to make treatment wetlands a more attractive component of urban water infrastructure.To assess the ability of open-water cells to exploit sunlight photolysis to remove trace organic contaminants from municipal wastewater effluent, a photochemical model was calibrated using measured photolysis rates for atenolol, carbamazepine, propranolol, and sulfamethoxazole in wetland water under representative conditions (Chapter 3). Contaminant transformation by hydroxyl radical and carbonate radical were predicted from steady-state radical concentrations measured at pH values between 8 and 10. Direct photolysis rates and the effects of light screening by dissolved organic matter on photolysis rates were estimated using solar irradiance data, contaminant quantum yields, and light screening factors. The model was applied to predict the land area required to achieve 90% removal of a suite of wastewater-derived organic contaminants by sunlight-induced reactions under a variety of conditions. Results suggest that during summer,…

▼ Pharmaceuticals have been detected in the environment at low concentrations. A major source of these pharmaceuticals is sewage effluent due to the failure of conventional sewage treatment processes to remove them. Amongst other sources of pharmaceuticals in sewage water, unused and expired medications and those returned to community pharmacies that are improperly disposed of can be a significant source. Currently, there is little data on the overall lifecycle of pharmaceuticals from their prescription or sale to the environment. Aims: The aims of this thesis were (1) to determine whether community pharmacies are sources of pharmaceuticals in sewage, (2) to detect and identify pharmaceuticals in New Zealand sewage and (3) to determine whether their removal from wastewater can be chemically enhanced. Methods: To establish how community pharmacies dispose of expired, unused and unwanted medications, a questionnaire was sent to 500 community pharmacies across New Zealand asking how they disposed of various types of dosage forms. The questionnaire also asked whether pharmacists thought a state-run disposal and destruction system for unused pharmaceuticals should be implemented. To determine pharmaceuticals in wastewater, samples of sewage influent and effluent were collected from a single sewage treatment facility and analysed for the presence of selected pharmaceuticals by liquid chromatography-tandem mass spectrometry (LC-MS/MS). To determine whether sewage treatment can be chemically enhanced, advanced oxidation and reduction processes (AORPs) were assessed for their ability to reduce the concentrations of three pharmaceuticals [oseltamivir (OS), trimethoprim (TMP) and enoxacin (ENX)] in wastewater. These AORPs included degradation by UV irradiation alone and in the presence of hydrogen peroxide (H2O2), a combination of hydrogen peroxide and iron (II) (the photoFenton process) and the photocatalyst, titanium dioxide (TiO2). In addition, the ability of natural organic matter (NOM) in the environment to enhance the removal of pharmaceuticals in water was investigated using the excited triplet state of benzophenone as a surrogate for NOM. Key Findings: Many pharmacists reported the disposal of liquid medications and Class B controlled drugs by flushing down the sink (44.7%, n = 338 and 58%, n = 287 respectively) indicating that community pharmacies are a source of pharmaceuticals in wastewater. Analysis of wastewater detected and identified seven pharmaceuticals (bezafibrate, carbamazepine, fluoxetine, metoprolol, paracetamol, sulfamethoxazole and trimethoprim) in samples of sewage influent and effluent but their concentrations were either too low to be quantified or were not significantly different from their respective limits of detection. In regards to the removal of pharmaceuticals from water, AORPs were shown to be effective at degrading OS, TMP and ENX, with H2O2 and TiO2 generally enhancing photodegradation. Most of the photodegradation processes obeyed first-order kinetics. A second-order kinetic model was… Advisors/Committee Members: Peake, Barrie M (advisor).

▼ It is believed that understanding the reactive intermediates is essential to unveil mechanisms of synthetic chemistry and biological processes. In the library of reactive intermediates, oxenium ions are highly reactive with the formula R−O+. These reactive intermediates possess lone pairs of electrons on their central oxygen atoms, permitting different energetically accessible electronic configurations. More importantly, reactive intermediates with diverse electronic structures would very likely bear distinct reactivities, and thus various reaction pathways may occur. In general, intermediates with closed-shell singlet states usually react as electrophiles, while ions with triplet states show typical radical reaction pattern, such as hydrogen atom abstractions. Moreover, the chemical formula of oxenium ions suggest that these species are isoelectronic to the better understood nitrene intermediates but bear a formally positive charge on a hypovalent oxygen atom, which is substantially interesting considering the high electronegativity value of oxygen element. Although oxenium ions have been proposed as intermediates in numerous processes, relative studies about these ions themselves are surprisingly rare, largely because the isolation of oxenium ions is utterly difficult due to the extremely short lifetimes. To probe these exceedingly short-lived intermediates, a combination of theoretical calculation and experimental laser flash photolysis (LFP) has been applied. On one hand, LFP technology has allowed us to directly observe these reactive intermediates within femtosecond time scale in the aspects of the absorption spectroscopy, Raman spectroscopy, etc. On the other, owing to the advanced theoretical models, computational investigation helps us to validate and interpret the experimental spectroscopic data. Moreover, the theoretical approach also provides a close insight to the spin configurations of these reactive intermediates, guiding us to design oxenium ions with desired electronic configurations. In this manner, appropriate photo-precursors are strongly demanded for generating corresponding oxenium ions photochemically. My research focuses on synthetically developing new photoprecursors which can potentially produce corresponding oxenium ions possessing intriguing electronic structures. LFP studies perform direct observation of these transient species. By comparison to the theoretical predictions, each transient species collected by LFP shall be attributed correctly. Photo product studies are conducted to determine the reactivities of these reactive intermediate. I have also carried out my investigation in searching for anomalous electronic configurations of oxenium ions using computational methods. Oxenium ions with different electronic configurations exhibit distinct reactivities, which are potentially useful for future synthetic applications. More importantly, reactive intermediates bearing triplet states, if well stabilized, are capable of acting as practical magnetic materials.

▼ Judicious addition of photolabile caging groups (PCGs) to protect biologically im- portant molecules, has enabled the development of many powerful chemical tools for the study of biological processes. These tools have the potential to be activated in a cellular setting by irradiation with light of appropriate wavelengths, restoring functionality, with excellent spatial and temporal control. This D. Phil. dissertation highlights two biologically relevant examples where PCGs can be applied: (i) 4,5-dimethoxynitrobenzyl (DMNB) caged derivatives of GSH and ESG, were synthesised and uncaging of the DMNB group at 350 nm to reveal the free Î±-carboxylic acid of the glycine residue was demonstrated. These molecules have the potential to probe the binding mode within the KefC KTN binding domain, a ligand-gated K+ efflux system, critical for bacterial response to electrophilic assault. The molecules are currently with collaborators awaiting further evaluation. (ii) The wavelength-dependent application of PCGs toward the study of protein post- translational modifications (PTMs) was developed. PTMs modulate protein function and have a ubiquitous role in a diverse range of cellular functions. A wavelength selective sequential pair of PCGs was developed and demonstrated in a tripeptide, using the diethylamino coumarin (DEACM), which was cleaved at 420 nm, and the DMNB caging group, which was subsequently cleaved at 350 nm. A chromatically orthogonal pair of PCGs, with possible applications in both organic synthesis and biological systems, incorporating the BODIPY-based and DEACM caging groups, which could be cleaved at 530 nm and 420 nm, respectively, was also developed. Photolysis was conducted on a tripeptide and hexapeptide and an in vitro application was demonstrated where when caged, the peptide was not susceptible to peptidolysis when incubated with enzymes. Following irradiation at 420 nm, the DEACM group was uncaged and the peptide underwent peptidolysis in the presence of Endoproteinase AspN, whereas following irradiation at 530 nm to uncage the BODIPY group, the peptide underwent peptidolysis in the presence of Endoproteinase LysC. These results not only provide conclusive evidence of the ability of this pair of caging groups to act in a wavelength orthogonal sense but also demonstrates the potential applicability of the pair to biochemical studies. This pair of PCGs represents the first example of an orthogonal pair of caging groups where both PCGs could be cleaved, at wavelengths longer than 400 nm, in a sequence independent manner.
