Spin crossover in iron(II) dinuclear helicates and tetranuclear cages
Amongst the 151 discrete di- to poly-nuclear spin crossover (SCO) active assemblies of Fe(II) published before July 2020, only 19 are Fe(II) triply bridged dinuclear helicates (Fe2L3) and only 6 are edge bridged tetranuclear ... -
On the functions of palladium (II) cages
This thesis consists of four chapters. Chapter 1 provides an overview of metallosupramolecular chemistry, detailing the three main approaches to self-assembled metallosupramolecular architectures: the ligand direct ... -
Discoveries from the alpine daisy Celmisia viscosa: unique diterpenes and flavones, and variation within the species
This thesis focuses on the natural product chemistry of the native Alpine daisy, Celmisia viscosa. Previous work on C. viscosa has shown the presence of the diterpenes epimanool and the rare halimadienol, also present were ... -
Carbon-rich cavitands from reduced-symmetry resorcin[4]arenes
Cavitands (or container molecules) possess an enforced cavity suitable for binding small guests in solution and the solid state. The aryl units of arene-rich cavitands act as both structural elements and binding sites to ... -
Investigating the Vibrational and Electronic States of Various pi-Conjugated Systems
The vibrational and electronic properties of a range of pi-conjugated systems were explored. Such systems included some donor-acceptor dyes in which their symmetry made computational analysis of their charge-transfer ... -
Exploration of the techniques and applications of δ2H, δ18O and δ13C stable isotope analysis for the authentication of raw cotton
As the practices of fraud and use of child labour in the cotton industry become more sophisticated and harder to prevent[1], undermining detection using falsified documentation becomes easy to achieve[2]. Stable isotopes ... -
Towards the synthesis of hydrogen bonded frameworks
Hydrogen-Organic frameworks (HOFs) are supramolecular materials constructed by linking organic molecules through intermolecular hydrogen bonds. HOFs are a lightweight alternative to MOFs and have been shown to be effective ... -
Thermochemical heat storage system utilizing low-grade heat sources: combined investigations, material development, design and integration
The cost of space heating is dependent on electricity prices because of its significant utilization of electricity. There was a 60% increase in the unit electricity price between 2005 and 2019 which is sure to further ... -
Donor acceptor systems; a study using vibrational and electronic spectroscopies and computational modelling
Spectroscopic techniques, namely electronic and vibrational spectroscopy, have been shown to be very powerful tools in providing insight into the excited state nature and dynamics of compounds and complexes. A mixture of ... -
Isoreticulation of an adamantane-based lithium framework
Isoreticulation is the “tweaking” of the structure of an already established metal-organic framework (MOF) to alter certain properties, while still maintaining the original parent topology. This work investigated the ... -
Towards Fluorescent Carbon Monoxide Releasing Molecules
This research project aimed to develop fluorescent analogues of the oCOm molecules reported by Larsen and co-workers.1 It was proposed that the attachment of phenanthrene-based fluorescent reporter groups to these CO ... -
Development of traceability tools based on metabolomics for milk products
Fraud is endemic throughout the food industry and a major concern to producers and consumers. Adulteration or substitution with an inferior product may cause economic or health problems. Milk is a foodstuff that is widely ... -
Thermoreversible hydrogels based on PEO stars
The aim of the project is to develop a range of hydrogels made from biocompatible monomers which could be used in various biomedical applications. The particular interest is on star-shaped block copolymers which consist ... -
The Pesticide Loss via Volatilisation (PLOVO) Model and an Environmental Fate Study of Chlorpyrifos
Pesticides are an important tool in modern crop management to ensure high quality and high yield food production. However, pesticide Volatilisation from agricultural fields can have a significant impact on non target, ... -
Chemistry of a Stable Vitamin C Glycoside in Apples (Malus spp.) and Other Fruit Crops
The primary aim of the research described in this thesis was to investigate an ascorbyl glycoside tentatively identified in crab apples (Malus sylvestris) by a non-targeted metabolomics study (unpublished thesis, J. Cho, ... -
Bridging the Gap: Synthesis of Bay-Annulated Hexa-peri-hexabenzocoronenes
This thesis consists of five chapters describing the bay-annulation of the planar hexa-peri-hexabenzocoronene towards a bowl-shaped hexa-peri-hexabenzocoronene where all six bay sites are annulated. Chapter one provides ... -
Carbon-rich coordination cages
This thesis consists of five chapters describing the synthesis and host-guest binding studies of various carbon-rich metallosupramolecular cages. Chapter 1 provides an introduction of the field of metallosupramolecular ... -
Understanding Semi-Volatile Pesticides Fate and Transport: Field and Laboratory Studies with Modelling Approach
The use of pesticides in the agricultural sector, alongside other technological advances, caused dramatic increases in crop yield but also accompanying increases in environmental concerns. Pesticide volatilisation and ... -
New macrocycles for polymerisation catalysis
This thesis concerns the synthesis of diphenylamine-based macrocycles for generating new dimetallic polymerisation catalysts. Chapter 1 introduces the target polymerisations we aim to catalyse, and reviews the current ... -
Modification of Catalytically Active and/or Switchable Complexes for Surface Attachment
The overall aim of this project was to take robust complexes which exhibit reversible redox, catalytic activity, or spin crossover (SCO), and design, prepare and characterise suitably functionalised analogues of them, in ...
