(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2019)This thesis, entitled “Anion Templated Self-Assembly – From Anion Complexes to the Formation of Supramolecular 2D Networks” covers the anion complexation and ATSA abilities of different sets of ligands. The work will be ... -
Mimicking ribonucleotide reductases: Biomimetic manganese complexes and their reaction with superoxide
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2019)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 ... -
Supramolecular soft materials and structural studies of a series of BTA and pyridine-dicarboxamide derivatives with various d-metal ions
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2019)As will be discussed in the introduction, the control and tuning of the self-assembly of supramolecular soft materials is an area of great current interest and importance. A particularly interesting motif for investigating ... -
Transmission electron microscopy and spectroscopy of carbon-based nanomaterials
(Trinity College (Dublin, Ireland). School of Chemistry, 2016)Carbon-based nanomaterials, such as graphene, Carbon Nanotubes and fullerenes, have attracted a great deal of interest from the materials research community; especially in electronic and sensing applications. Despite all ... -
Formation of an ordered porous polymer microstructure by water droplet templating
(Trinity College (Dublin, Ireland). School of Chemistry, 2010)This thesis examines the complex system of competing mechanisms involved when evaporation of a polymer solution induces sufficient cooling to drive condensation of water droplets onto the solution surface, where they pack, ... -
Computational studies of lithium complexes and alkanes
(Trinity College (Dublin, Ireland). School of Chemistry, 2001)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, ... -
Enantioselective receptors for anionic species
(Trinity College (Dublin, Ireland). School of Chemistry, 2001)This project aimed to design, synthesise and test neutral, tripodal steroid receptors based on cholic acid 1 that were capable of binding to carboxylates (especially N-acyl-a-aminoacid carboxylates), and differentiating ... -
A study of Hydrogen-Deuterium exchange on the photophysical properties of Ruthenium (II) Polypyridyl complexes
(Trinity College (Dublin, Ireland). School of Chemistry, 2002)This main aim of the present study is to investigate the effect of protium-deuterium exchange on the photophysical and excited state energetics of Ru(ll) complexes by UV-Vis absorption, both steady-state and time-resolved ... -
Development of novel organocatalysts towards the kinetic and dynamic resolution of chiral enolisable anhydrides
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2018)In this thesis we explore the possibilities offered by the bifunctional properties of a series of organocatalysts derived from cinchona alkaloids for the promotion of novel asymmetric transformations. In particular, we ... -
Development of Enantioselective Processes Catalysed by Novel Asymmetric Bifunctional Phase-Transfer Organocatalysts
A new family of chiral bifunctional phase-transfer catalysts were developed to promote an enantioselective SN2 reaction for the construction of malleable oxindoles with all-carbon quaternary stereocenters in high yield and ... -
Diffusion within fluorite structured materials and the effect of defects
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2018)There is a current global movement toward renewable sources and away from non- renewable energy sources. This can be attributed to the limited resources and harmful effects, both economic and environmental, of non-renewables. ... -
Organocatalysed transformations of enolisable cyclic anhydrides
