Discotic compounds and columnar materials within organic photovoltaic material blends: synthesis and characterisation
Discotic organic polyaromatic semiconducting materials have been utilized in different organic electronic applications, specifically as light harvesting material for organic photovoltaics (OPV), the development of which, ...
Aqueous Cu2ZnSnS4 & Cu2ZnSnSe4 nanocrystal inks and their non-toxic alternative to selenization
Thin-film solar cells have already reached grid parity with conventional fossil fuel energy sources, and slightly undercut traditional crystalline silicon solar cells, however they still have the potential to lower their ...
Valence tautomerism and exchange interactions in cobalt-dioxolene complexes
This thesis presents an experimental and computational investigation of cobalt and cobalt-dioxolene complexes, focusing on valence tautomeric (VT) behavior, single-molecule magnet (SMM) properties and magnetic exchange ...
Morphological advancements through sidechain engineering for organic photovoltaic applications
Organic photovoltaics (OPV) materials are an established class of light-harvesting, solution-processable organic semiconductors. These materials have attracted substantial interest from the scientific and commercial ...
The oxidative damage of biological molecules by air pollutants NO2● and NO3●
Air pollution is perceived as the world’s greatest environmental risk to human health. According to the World Health Organization (WHO), air pollution is responsible for the deaths of about 7 million people each year. In ...
Coinage metal hydrides: reactive intermediates in catalysis and significance to nanoparticle synthesis
The coinage metal hydrides of copper, silver and gold have applications in catalysis and nanoparticle synthesis. Coinage metal hydrides are key intermediates in the chemical transformations of a range of substrates including ...
Design and synthesis of chemical tools for studies of carbohydrate active enzymes
Glycoside hydrolases (GH) are enzymes that catalyse the hydrolysis of glycosidic linkages. They are classified into over 150 families based on their primary amino acid sequence. Family GH99 endo-α-1,2-mannosidases/endo-α ...
It’s hip to be square: a cyclobutene diester approach to alkyl citrate natural products
This thesis features an enatiospecfic synthesis of a key alkyl citrate retron that was leveraged in the total syntheses of squalene synthase inhibitors (-)-CJ-13,982, (-)-CJ-13,981 and (-)-L-731,120 (featured in Org. Let. ...
Phytoextraction of mercury (Hg) and gold (Au) from contaminated mine tailings and biosolids
The present study is based on a long-term goal of using phytotechnologies to rehabilitate Hg-contaminated substrates like mine tailings and biosolids with the additional value of recovering Au residues. To address this ...
Amide assembly through Ag(I) promoted reaction of thioamides bearing self cleaving auxiliaries
Synthesis of amide bonds is an important issue in organic chemistry but is often overlooked as a contemporary challenge. Existing methods are reaching their limits and new chemical approaches are being developed. The Ag(I) ...
