Au cours des dernières années, les avancées dans le domaine des machines moléculaires ont été remarquables. Néanmoins, la réalisation d'un mouvement unidirectionnel contrôlé au sein de ces nanostructures reste compliquée. L'objet de cette thèse est d'exploiter l'asymétrie intrinsèque de la cyclodextrine (CD) pour développer des machines moléculaires capables de réaliser un mouvement unidirectionnel. Une série de [2]rotaxanes, comportant une α-CD perméthylée simple ou fonctionnalisée avec une amine sur le col primaire a été synthétisée.Dans une première partie, un mécanisme de cliquet d'informa

The natural organic host, cyclodextrin and its chemically modified derivatives, are utilised as hosts for the inclusion of a range of guests. The study contributes to understanding the fundamental factors influencing selectivity of binding and the stability of the complexes formed when a guest is bound essentially at two recognition sites.

Lipophilic dialkylated-a-, β- and γ-cyclodextrin derivatives were used as selective ionophores for a series of clinically relevant ammonium ions, and as enantioselective ionophores for both a- and β-aryl ammonium ions. Sensitive and selective potentiometric detection of the local anaesthetics lidocaine and bupivacaine was achieved by using 2,3,6 trioctyl-β-cyclodextrin as the ionophore, leading to micromolar detection limits. Interference studies showed that the simulated clinical electrolyte background caused minimal interference whereas organic interferents of similar size and charge caused

Nitroaromatic explosives, such as trinitrotoluene (TNT), are of particular environmental concern due to their recalcitrance in soils and their potent toxicity and mutagenicity to both aquatic and mammalian species.

As a result, there is widespread contamination of soils by TNT around weapons manufacture, testing, and disposal facilities.

Mestrado em Bioquímica - Bioquímica Alimentar<br>A inclusão em ciclodextrinas (CDs) de hóspedes multi-componente, tais como óleos essenciais e extratos de plantas, é um tema atual e útil para uma série de aplicações nas indústrias alimentar, cosmética e farmacêutica. No presente trabalho foram estudados dois destes sistemas, tendo por hóspedes o óleo essencial de Cistus ladanifer e uma mistura de gingerois extraídos de rizoma fresco de gengibre. A composição do óleo essencial de C. ladanifer foi estudada por GC-MS, tendo-se identificado 94,3% dos seus componentes e determinado a massa molecul

Abstract:
Le développement de nanotransporteurs basés sur des lipides, des polymères et des nanoparticules avec des propriétés «sur mesure» pour augmenter l’efficacité de médicaments, fait l’objet de recherches intensives. Toutefois, la physico-chimie subtile des intéractions polymères-lipides and nanoparticules-lipides présente encore de larges domaines mal compris et de nombreuses questions sans réponse. Ce projet de recherche doctoral utilise des techniques de visualisation (Cryo-MET, LSCM), et de caractérisation (ITC, DSC, SAXS, SANS, QCM-D) avancées pour obtenir des informations nouvelles sur les m

Abstract:
Triprolidine hydrochloride (C₁₉H₂₂N₂.HCl.H₂O) (TPH) is a well-known antihistamine drug. It melts between 118°C and 122°C and the amount of water present is 4.5 mass percent. TPH is reported as being photosensitive and must be stored in sealed, light-tight containers. The thermal stabilities of TPH and of 1:1 molar and 1:1 mass ratio physical mixtures of TPH with beta-cyclodextrin (BCD) and with glucose have been examined using DSC, TG and TG-FTIR, complemented by X-ray powder diffraction (XRD) and infrared spectroscopic (IR) studies. Thermal studies of the solid TPH/BCD mixtures indicated that

Abstract:
Cyclodextrins (CDs) are cyclic oligosaccharides of various sizes containing several α-(1→4)-linked D-(+)- glucopyranose units. The commercially available ones comprise six, seven or eight glucose units, named respectively α-CD, β-CD and γ-CD. Their truncated cone-like and well-defined cavity are particularly attractive for the encapsulation of a variety of substrates. As such, they found numerous applications in many areas of chemistry. A recent development, from which the present work is inspired, consisted in covalently linking transition metals to CD cavities in order to perform and study c
