▼ The photochemistry of some analogs of insect growth regulators (IGR's) was studied. Methyl geranate, TY, was synthesized and the mechanisms of its photochemical reaction pathways were studied by a variety of techniques. Direct irradiation of 71 in ether leads to the formation of five new products: 98, the product of a [1,3] sigmatropic shift; 72, a bicyclo[2.1.1]hexane derivative; 73, a cylclopentane derivative; 100, the product of in-chain deconjugation to the Z isomer; and 97, the product of isomerization about the C-2 bond. Irradiation in the presence of propiophenone as a triplet sensitizer lead to the formation of only 72, 73 and 97, identifying them as arising from the triplet excited state. Irradiation of 71 in ether with varying amounts of base lead to the formation of (in addition to products already mentioned) 99 and 100, the other two possible deconjugation products. Examination of Scheme 29 leads to the derivation of the kinetic rate expressions in Scheme 31, and plotting the ratios of 99/73, 100/73 and 101/73 yields values for the relative rate of [1,5] sigmatropic shift of hydrogen from a photodienol species (119, 121, 123) to regenerate starting esters (71, 97) rather than going on to deconjugation products (99, 100, 101). It was found that the relative rates of sigmatropic shift for 119 and 123 were nearly identical but 121 was about 75 times slower. This decrease in the relative rate for 121 is ascribed to the extra steric repulsion in 121, causing it to adopt the unreactive s-trans conformation and thus slowing the reaction. Insect juvenile hormone, 74, was synthesized and irradiated in ether and was found to undergo photochemical processes similar to that of 71. The primary photoprocess is isomerizatrion about the C-2 and C-6 double bonds. Isomerization about the C-6 bond was unexpected and indicated the intermediacy of an exciplex. To study the role of exciplexes in the E/Z isomerizartion of isolated double bonds in the juvenile hormone, 74, the unsymmetrically terminated analog 92 and the dihydro analog 93 were synthesized. Irradiation of 92 and 93 in solvents of varying polarity (ET) lead to an increase of the quantum yield of E/Z isomerization for both 92 and 93, indicating the intermediacy of an intermolecular exciplex. to study the role of intramolecular exciplexes 92 and 93 were irradiated in ether at increasing dilution (0.1 M - 0.0008 M). It was found that the intermolecular exciplex is the major contributor in the concentration range studied without any evidence for an intramolecular exciplex.

▼ Photochemical reactivity of several dibenzannelated systems has been investigated to demonstrate that the driving force inherent in many of their reactions is the attainment of a 4n π-electron system or intermediate in S1. It has been shown that the inherent driving force for the benzylic C-H bond ionization in 9H-xanthene (125) and 9H-thioxanthene (136) is the formation of 8π-electron cyclically conjugated carbanion intermediates 130 and 137, respectively, in S1. Formation of deuterium incorporated products when 125 and 136 are photolyzed in NaOD-EtOD solutions and protium incorporation in products when photolysis of 123 and 134 is carried out in NaOH-EtOH is consistent with the intermediacy of carbanions in these reactions. Fluorescence quenching of 123 and 125 by ethanolamine in CH3CN gave linear Stern-Volmer plots, with kq = (2.16 ± 0.05) x [special characters omitted] for 125 and (1.12 ± 0.05) x [special characters omitted] for 123, which corresponds to an isotope effect for quenching by ethanolamine, of [special characters omitted] = 1.92 ± 0.04. Enhanced stability of 8π carbanions in S1 is further evidenced in the photodecarboxylation of xanthene-9-carboxylic acids (142 and 145) and thioxanthene-9-carboxylic acids (147 and 148) in aqueous solution. The intermediacy of carbanions has been demonstrated in the product studies carried out in 80% [special characters omitted] solution. A mechanism has been proposed which involves heterolytic bond cleavage of the carboxylate ion in S1 to give intermediate carbanions. Additional support for the excited state stability of 4n systems comes from the studies of 155. Photoexcitation of bent 155 results in its planarization to give planar 155 in S1. The driving force for this change of conformation of 155 is believed to be the attainment of a conjugated 8π-electron internal cyclic array in S1. Photolysis of substituted suberenes in aqueous [special characters omitted] results in benzylic C-H bond cleavage in these systems in S1 the efficiency of which is greatly affected by the nature of substituent present. Results obtained in this study are consistent with benzylic C-H bond cleavage, with H2C acting as the base, to give intermediate carbanions in S1. Quantum yields of exchange in [special characters omitted] (L = H or D) and in a variety of other solvent mixtures have been measured. The photochemistry of xanthenium (99 and 114) and thioxanthenium (219) cations has been studied in aqueous [special characters omitted] in the presence of di- and trimethoxybenzenes. It has been shown that the primary photochemical step is electron transfer from methoxybenzenes to singlet excited 99 and 114. The radical intermediates thus generated subsequently react with 02 to give peroxy compounds as final products. These and other results of the photochemistry of dibenzannelated systems show that there is much interesting photochemistry to be discovered in these molecules.

▼ Previous research on the photolyses of ketene at 2700 A and 3650 A has shown that considerably different mechanisms are necessary to explain the experimental results. Exactly how the process of deactivation of the excited ketene molecule was affected by change in wavelength was not fully understood. It was felt that investigations of the primary quantum yields at intermediate wavelengths would be fruitful in obtaining a better understanding of the variation of reaction mechanism with wavelength. At 2700 A, using pure ketene, the only primary process is dissociation and therefore the primary quantum yield is unity, while at 3650 A dissociation occurs by way of an excited state which has a finite lifetime during which the excited ketene molecule may undergo collisional deactivation and internal conversion. At 3650 A therefore the primary quantum yield is much less than unity even at low pressure, and decreases with increasing pressure. This research has shown that in the case of ketene at 3130 A the primary quantum yield is approximately unity at low pressures, 20 mm., and decreases to 0.6 at one atmosphere. At 3340 A the primary quantum yield is approximately 0.7 at 26 mm. and 0.2 at 400 mm. and increases with increasing temperature. The dependence of primary quantum yield on pressure at 3130 A and 3340 A was anticipated and can be explained by almost the same mechanism as that proposed for 3650 A radiation. The amount of radiation absorbed during each run was very accurately measured and it was therefore possible to determine quantum yields to within ± 2% at 3130 A, and within ± 10% at 3340 A. For the photolysis at 3650 A the ratios of the rate constants of collisional deactivation and product formation and of internal conversion and product formation at 26° C are 4.6 x 10⁴ litres/mole and 28 respectively. At 3130 A and 37°C this research has shown these ratios to be 16.8 litres/mole and zero respectively, while at 3340 A the ratios are 1.64 x 10² litres/mole and 0.25 at 37°C and 0.99 x 10² and 0.1 at 100°C.

▼ Vibrationally excited oxygen with up to 15 quanta of energy has been produced in the flash photolysis of NO₂ . When the NO₂ was selectively photolysed such that only radiation below 4000 A° was admitted to the reaction vessel the highest level observed was reduced to v" = 11 which in terms of vibrational energy corresponds to the exothermicity of the reaction O + NO₂ —> NO + O₂ Relative population ratios for the successive vibrational levels v" = 6 to 11 were calculated for both the filtered and unfiltered photolysis of NO₂ using two independently calculated arrays of Franck-Condon Factors. In both cases the ratios showed that the population distribution was definitely non Boltzmann. in that the levels were almost equally populated. The distribution for the unfiltered experiments gave a pronounced dip at v" =11 indicating that the levels 12 ≤ v" ≤ 15 are formed by a second reaction. This reaction has been shown to be Q+ NO*₂—> O*₂ v" ≥12 +NO where the NO₂ is probably electronically excited. The adiabatic flash photolysis of both NO₂ and SO₂ has been investigated. These spectra show weakening of their banded structure up to 100 microseconds after the flash and then gradual strengthening until back to normal by 10 milliseconds. This effect is well known for SO₂ and has been postulated to be the result of the formation of a high temperature isomer of SO₂. Subsequently the postulated isomer had a transient spectrum in the vacuum ultraviolet assigned to it. We have found that the weakening of both the NO₂ and SO₂ banded structure is the result of temperature broadening. The spectrum assigned to the SO₂ isomer has been extended. It has also been produced from the flash photolysis of SO₂ under isothermal conditions showing that its assignment to a high temperature isomer is incorrect. From kinetic data this spectrum in the 1800 A° region and another the 1400 A° region has been tentatively identified as two triplet systems of SO.

▼ This thesis presents the synthesis of neutral and cationic metallophthalocyanines and their gold nanoparticles conjugates. The spectroscopic characterization of these compounds is presented herein. The studies presented in this work shows that the conjugation of gold nanoparticles influenced both photophysical and photochemical properties. Gold nanoparticles were found to enhance the singlet oxygen quantum yield while lowering the fluorescence quantum yields. This work also looks at the effect of anisotropic gold nanoparticles such as nanorods and bipyramids on the photophysical behaviour of the metallophthalocyanines. The effect of the size of the gold nanorods was investigated herein. The results show that photophysical and photochemical properties can be influenced by both size and shape of the nanoparticles. Physical characterization about the loading of nanoparticles was also looked into. Parameters such as the surface area, the number of surface atoms, the number of atoms as well as the number of nanoparticles loaded on the surface of the phthalocyanines were studied. The self-assembled monolayers formed by phthalocyanines on gold surfaces were studied using the X-ray photoelectron spectroscopy (XPS). The gold nanoparticles synthesized herein include both organic and water soluble, different capping agents (citrate, tetraammonium bromide (TAOBr) and cetrimethylammonium bromide (CTAB). The concentration of the gold nanoparticles was measured on the inductively coupled plasma (ICP) and their size and shape were obtained from the transmission electron microscopy (TEM) images. A cationic aluminium phthalocyanine and its conjugates were used for photoinactivation of bacteria and fungi. The results show significant reduction and higher activity in the presence of gold nanoparticles, especially nanorods. A small chapter in this work presents an attempted work on the binding of metallothionein protein with protophorphyrin (IX). The pH and concentration dependent binding studies were investigated

▼ The present study focuses on the development of high surface area nanostructures and their applications in the removal of gas-phase contaminants through both photocatalytic and adsorptive techniques. Particular importance was given to ensure the commercial viability of the developed technologies. Due to its industrial importance, the elimination of siloxanes from biogas was investigated with major interest. Through electrospinning techniques it was possible to synthesise a large number of nanostructures: TiO2, SiO2, WO3, and WO3 doped TiO2 nanofibres. These structures were further enhanced through templating techniques in order to make core/shell SiO2/TiO2 nanofibres, hollow TiO2 nanofibres, and porous TiO2 nanofibres. Additionally, the synthesis of SiO2 aerogel granules under ambient conditions was performed through a novel, commercially facile, technique. The created nanostructures were initially employed as adsorptive materials for the removal of gaseous siloxanes from static environments. The adsorption kinetics and total siloxane loadings of the created structures were compared to those of P25, commercial silica gel, and the industrial PpTek siloxane removal standard. Although the commercial adsorbents were shown to perform better than the created nanostructures, the nanostructure surface areas were seen to lead to enhanced adsorptive properties with respect to P25. TiO2 nanofibres, porous TiO2 nanofibres, WO3 doped TiO2 nanofibres, and P25 were further used to study the photodecomposition of siloxanes in a static environment. Through kinetic studies it was possible to establish that 1 mol% WO3 doped TiO2 nanofibres were an ideal candidate for the photodecomposition of gaseous siloxanes, with a decomposition rate 126.5 % larger than that of simple P25. P25 was coated on glass beads through a novel technique in order to photocatalytically degrade contaminants in gas flows. Through the decomposition of both siloxanes and VOCs it was possible to study the turnover numbers and conversion levels of the reactions. The poisoning of the catalysts was identified and countered through industrially viable recoating techniques. From these studies it was possible to develop a prototype reactor for the photodecomposition of siloxanes in biogas. Finally, the synthetic properties of the flow reactors were studied by carrying out the photoepoxidation of hexene over P25. These studies were further enhanced by reacting the partial photoepoxidation products of the reactor's exhaust in order to create rare and complex organic species.

▼ Energy harvesting directly from sunlight has attracted tremendous attention owing to its great potential for low-cost and clean hydrogen production. However, the current photoconversion efficiency from nanostructured metal oxides remains low due to a number of factors, such as low surface area, limited light absorption, poor electron mobility and high electron-hole recombination. In this research, a number of approaches have been carried out to overcome these difficulties. Firstly, changing the morphology of nanomaterials will help to increase the effective surface area of the photoanodes. ZnO nanotubes were prepared and the photoelectrochemical measurements revealed an efficiency of 3 times higher than their nanorod counterparts. In addition, the combination of ZnO nanorods with a 3D metal substrate, stainless steel mesh, showed a further enhancement in the water splitting efficiency by two-fold when compared with that on a planar substrate. Secondly, the hybridisation of two different metal oxides was studied by creating a heterojunction to improve the charge separation, extending the light absorption and increasing the total surface area of the electrode. In this work, both urchin-like ZnO nanorod arrays on TiO2 hollow hemispheres and 1D BiVO4/ZnO nanorod films displayed synergistic enhancement in photoelectrochemical water splitting efficiency. Thirdly, doped ZnO nanostructures with different optical and/or electrical properties were tailored for photoelectrochemical water splitting and gas ionisation sensing applications. The photoelectrochemical water splitting performances of the doped ZnO nanostructures was improved by at least 27% due to increased light absorption. Conductive Y-doped ZnO nanorods were prepared and applied in gas ionisation sensor application. The measurements revealed that both the selectivity and sensitivity of Y-doped ZnO nanorods were enhanced with respect to undoped ZnO nanorods. Furthermore, the effect of UV illumination on gas sensitivity was also investigated. In summary, different approaches and namomaterials have been adapted and demonstrated in this thesis, for the design of specific photoanodes/electrodes for specific applications.
