Ferrocene-derived Heterobimetallic Supramolecular Architectures: Synthesis, Guest Encapsulation and Stimulus-Responsive Studies
… stimuli and have the ability to encapsulate guest molecules within their internal cavities. As the majority of studies into homometallic stimuli-responsive supramolecular systems has focused on total disassembly of the architecture, this provided an opportunity to explore reversible partial …

Control and Prediction of Polymer Network Structure and Connectivity for Sustainability, Stimuli-Response, and Catalytic Function
… a cavity which is known to bind small molecule guests. We systematically study the influence of guest binding on the physical properties of gels containing Pd2L4 cross-links and demonstrate that this feature can be used to tune bulk dynamics, and expand gel stability and assembly conditions, …

Allosteric Interactions in Coordination Cages
… inhibit their activity in response to molecules binding around their periphery. Synthetic receptors that can mimic this allosteric binding behaviour extend the potential applications of host-guest chemistry to programmable molecular systems. Modulating the degree and magnitude of interaction …

Structures and Applications of Porous Coordination Cages
… PCCs create in solution allows for interesting guest-binding behaviors inside the cavity, which has been exploited as catalytic sites, gas binding and storage and drug binding for cellular delivery. This dissertation work seeks to gain more understanding into the PCC as a host system in the …

Characterization and Synthesis of Cyclodextrin Inclusion Complexes and their Applications as Fluorescent Probes for Sensing Biomacromolecules
… cavity that allows them to form stable host-guest complexes with lipophilic molecules. This combination of functionality and guest binding ability makes CDs important scaffolds for the design of functional supramolecular systems. This thesis explored the interaction of …

Hexagonally-Packed Helical Oligo(m-Phenylene Ethynylene) Nanotubules via Structural Modification and Guest Templation
… powder diffraction (WARD and SAXD). Terpene guest binding was also examined using circular dichroism (CD) spectroscopy. The addition of endo-phenoxy methylene tert-butyl esters and carboxylic acids to the seven and ten positions of a symmetrically-capped hexadecamer was found to slightly …

Synthesis of Higher Homologues of Cucurbituril Derivatives and Evaluation of their Supramolecular Properties
… alkyl substituents on Q[6,7] modify the host guest binding behaviour with regard to increased binding constants and slower rates of exchange. The reasons for these changes have been discussed with reference to their substitutent effects upon the electronic characters of their portals and …

Supramolecular derivatisation of bioactive molecules via co-crystallization and cyclodextrin inclusion complexation
… distinct complexes of β-CD with fluconazole as guest having 2:1 host-guest stoichiometry were isolated. While these two hydrated complexes had been identified recently by previous researchers and the X-ray structure of one of the crystal forms had been partially resolved, their characterization …

Supramolecular effects in pyridinium compounds and their application towards practical redox flow battery systems
… systems. In a first demonstration, both the host-guest chemistry and existing tonne-scale production capacity of both cucurbit[*n*]uril (CB[*n*]) macrocycles and methyl viologen are leveraged to advance an additive concept for AORFBs that enables stable and tuneable multi electron accessibility – …

Study of ternary complexes of cucurbit[8]uril and their applications in self diagnostic composites
… sensors. Macrocyclic receptors that form host guest complexes with organic molecules, provide a unique platform for the formation of tailor made materials with programmable properties for specific applications. The cucurbiturils are one such class of receptors that have garnered increasing …
