Self-assembly of synthetic and biological components in water using cucurbit[8]uril

Zayed, Jameel Majed January 2012 (has links)
This thesis discusses progress made towards assembling molecular building blocks in the presence of our molecular host of choice, cucurbit[8]uril (CB[8]). Our studies on the self-assembly of synthetic and biological components in water bridge overlapping conceptsand techniques drawn from the fields of synthetic organic chemistry, supramolecular self-assembly, and applied NMR techniques. Chapter 1 introduces the reader to chemical complexity, and how supramolecular chemistshave advanced in their capability of assembling more complex molecular architectures. The discussion focusses particularly on self-assembly carried out in the aqueousphase, and how, like in biology, molecular design of the building blocks become criticalin enabling non-covalent assembly to occur in this dynamic, and relatively competitiveenvironment. The cucurbit[n]uril family of molecular hosts are then introduced with anoverview of their modes of binding, and affinities towards typical guests. Finally, a practicalintroduction to NMR methods gaining prominence in supramolecular chemistry ispresented. In particular, the use of diffusion NMR, a key tool for probing the solutiondynamics of molecular assemblies, is highlighted. Chapter 2 details work carried out on the CB[8]-mediated self-assembly of supramolecularblock copolymers from polymeric, and small molecule building blocks. Here, endgroup-functionalised polymer guests were shown to assemble with small molecule ditopicguests in the presence of CB[8] to form block copolymers. Copolymers of various molecularweights were assembled, and the supramolecular complexes were studied usingsolution viscometry and diffusion NMR. This study represented the first use of diffusionNMR for probing the assembly of polymeric guests with CB[8].Chapter 3 describes the self-assembly of CB[8] with complementary ditopic guests. Highmolecular weight supramolecular polymers are known to form through the step-growthassembly of complementary ditopic building blocks. Here we sought to probe CB[8]?sability to drive supramolecular polymerisation. Solution viscometry, ESI-MS, and diffusionNMR were used to investigate the self-assembly process, which indicated that cyclicoligomers had formed. The relatively low solubility of CB[8] in water was thought to bea major limitation to polymer formation in this instance. Important observations relating to the effect of salts on the solution viscosities and stabilitiesof the complexes, are also discussed. Chapter 4 places emphasis on the synthetic methods employed towards preparing multivalentguests for CB[8] binding studies. Our synthetic guests were based on watersolubleoligomers of ethylene glycol. A bidirectional elongation route is presented foraccessing higher molecular weight, and monodisperse ethylene glycol oligomers (n = 12)in suitable purity. Chapter 5 describes the assembly of protein-polymer conjugates, and the versatility ofdiffusion NMR as a means to probe the assembly process. Here, end group-functionalisedpoly(ethylene glycol) guests were appended to bovine serum albumin (BSA) through amixed chemical ligation-self assembly protocol. The NMR studies conducted are emphasisedhere, which served to complement other characterisation methods used thatare reported elsewhere. Chapter 6 discusses ongoing work on lipid-based guests, and the resulting liposome assembliesformed. Head group-functionalised phospholipid guests, and cholesterol-basedguests were synthesised. Phospholipid guests were obtained through an enzymatic route,a novelty in our group. Dye-encapsulated liposomes were then assembled, purified, andcharacterised by fluorescence microscopy. Finally, we sought to optimise lipid formulationsto enhance liposome stability, towards conducting molecular recognition studies inthe presence of CB[8].Chapter 7 then closes the thesis with concluding remarks that summarise the describedresearch, while highlighting points of note.

Approche exploratoire de l’expérience de repas gastronomique - éléments mémorisés et familiarité client : Le cas des Grands Chefs Relais & Châteaux / Exploratory research on gourmet meal experience - remembered elements and guest’s familiarity : The case of Grands Chefs Relais & Châteaux

Bayet-Robert, Philomène 16 December 2011 (has links)
Cette recherche exploratoire s’articule autour du concept d’expérience client et de sa mémorisation dans le contexte de la restauration gastronomique, spécifiquement dans les restaurants des Grands Chefs Relais & Châteaux. Cette thèse a pour objectif de comprendre ce qui constitue une expérience de repas gastronomique via l’étude des éléments mémorisés par les clients. Un dispositif méthodologique en trois temps est mis en place : deux phases d’entretiens qualitatifs (n=65) et une phase quantitative (questionnaire administré en ligne, n=1855). Les échantillons sont structurés autour du critère de langue (francophone, anglophone et germanophone) et de la fréquence de consommation. L’analyse des données collectées permet de dégager d’une part les rubriques qui composent l’expérience mémorisée par les clients, d’autre part de mesurer l’influence de la familiarité individuelle sur l’interprétation des composantes de l’expérience de repas. Ce travail aboutit à l’élaboration d’un outil opérationnel à destination des Grands Chefs et des managers de restaurants. / This research is integrated into the guest experience concept and its memorization in the area of Grands Chefs Relais & Châteaux’ restaurants. This thesis aims to understand the constitution of a gourmet meal experience according to guests’ memories. A three-step methodological approach is set up: a double qualitative phase (interviews, n=65) and a quantitative phase (on-line questionnaire, n=1855). Samples are structured regarding languages (French, English and German) and consumption frequency. Data analysis permits to identify categories describing a meal experience as memorized by guests, and to measure the influence of individual familiarity on the interpretation of experiential components. This work leads to the elaboration of an operational tool dedicated to Grands Chefs and restaurant managers.

Structures and Characteristics of Macromolecular Interactions in Gas Phase Using Fourier-Transform Ion Cyclotron Resonance Mass Spectrometry

Shen, Jiewen 09 December 2020 (has links)
This dissertation investigates non-covalent macromolecular chemistry using Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) based techniques. The included studies reveal the impact of molecular structure on conformation and binding energetics. Supramolecules that might be too heavy to be dissociated in single collision-induced dissociation (CID) were dissociated using sustained off-resonance collision induced dissociation (SORI-CID) techniques. Relative binding energies and thresholds were evaluated for various macromolecular host-guest systems. Besides the non-covalent binding energies, conformation characterization was undertaken by a novel method to determine collision cross sectional areas using FTICR (CRAFTI, and multi-CRAFTI), initially developed by the Dearden lab. The systems chosen for further understanding of macromolecular interactions include calixarene-alkali metal complexes, cucurbit[5]uril-alkali halide complexes and cryptand-alkali metal complexes. The results were found to be consistent with expected behavior, and strongly correlated with predictions from computations. Size- and shape selectivity, as well as host-guest polarizability, are the main factors that govern the non-covalent macromolecular interactions that control complex conformation and dissociation. The results demonstrate the ability of FTICR to simultaneously determine binding energy, structure and conformation, which are the most important aspects for determination of comprehensive molecular characterization.
