Abstract:
Metal-organic frameworks (MOFs) present potential for various applications such as gas sorption, gas storage, sensing, drug delivery, and catalysis. This attracts researchers to design and synthesize MOFs that can respond to a specific application. In this thesis, mixed ligands 34pba and 44pba ligands (34pba = 3-(4-pyridyl)benzoate, and 44pba = 4-(4-pyridyl)benzoate) and Co2+ metal salts were used to synthesize porous MOFs {[Co(34pba)(44pba)]·DMF}n (1) and {[Co(34pba)(44pba)]·(C3H6O)}n (2), with DMF = N,N'-dimethylformamide and C3H6O = acetone through solvothermal reaction.

Abstract:
Metal-organic frameworks are a new class of porous materials that have potential applications in gas storage, separations, catalysis, sensors, non-linear optics, displays and electroluminescent devices. They are synthesized in a "building-block" approach by self-assembly of metal or metal-oxide vertices interconnected by rigid linker molecules. The highly ordered nature of MOF materials and the ability to tailor the framework's chemical functionality by modifying the organic ligands give the materials great potential for high efficiency adsorbents. In particular, MOFs that selectively adsorb

Abstract:
Mercury is one of the most serious heavy metal pollution sources that threaten people’s health. For decades, people have developed many technologies and materials to capture mercury from flue gas of coal-fired plant. Currently, the most effective material for mercury absorption is powdered activated carbon, which shows increased efficiency when modified with halogen functional groups such as bromine. Metal-organic frameworks (MOFs) have potential applications in mercury capture due to their fantastic properties such as high porosity and high thermal stability. More important, their pore sizes

Dans cette thèse, on réalise des études basées sur les méthodes de simulation numérique (Dynamique moléculaire ab initio notamment) des propriétés physico-chimiques des adsorbants cristallins utilisés industriellement, comme les zéolithes,ou qui pourraient l’être dans le futur, comme les matériaux hybrides MOFs (Metal–Organic Frameworks). On s’intéresse en premier lieu aux propriétés d’adsorption des fluides moléculaires et de leurs mélanges, mais aussi au comportement mécanique et thermique des solides nanoporeux. Il s'agit d'expliciter des relations structure-propriétés, par le biais de simu

Abstract:
L'émergence d’un nouveau système nanoparticulé dans le domaine biomédical, les matériaux hybride poreux du type MOF (pour Metal Organic Framework), a récemment attiré beaucoup d'attention en raison de leur grande versatilité structurale et chimique. En particulaire, le trimésate de fer(III) mésoporeux (MIL-100; MIL pour Matériau de l'Institut Lavoisier) a démontré des capacités remarquables de stockage de médicaments avec leur libération contrôlée dans des conditions physiologiques, ainsi que des propriétés en imagerie très intéressantes.Néanmoins, avant toute bioapplication, il estnécessaire

Abstract:
The development of a new technique capable of analyzing compounds crystallographically without first needing to crystallize them has been recently described. The present thesis aims to demonstrate the potential of such a technique, which utilizes crystalline sponges, in order to regularly order guest compounds in a porous media. The structural stability of the molecular sponges, which are highly porous metal-organic frameworks (MOFs), is first investigated, revealing that the Co-based MOF, 1, undergoes two remarkable transformations. This thesis also demonstrates how the technique can be emplo

Abstract:
The synthesis of a scandium aluminium methylphosphonate ScAl₃(CH₃PO₃)₆ isostructural to the aluminium methylphosphonate AlMePO-α and with permanent microporosity is reported here for the first time. Structural characterisation of three lanthanide bisphosphonate structures (I,II,III) with the light lanthanides and N,N'-piperazine bis-(methylenephosphonic acid) and its 2-methyl and 2,5-dimethyl derivatives is described. The framework of structure type I shows considerable flexibility upon dehydration with a symmetry change from C2/c, a = 23.5864(2) Å, b = 12.1186(2) Å, c = 5.6613(2) Å, β = 93

Abstract:
Metal-organic materials (MOMs) represent a unique class of porous materials that captured a great scientific interest in various fields such as chemical engineering, physics and materials science. They are typically assembled from metal ions or metal clusters connected by multifunctional organic ligands. They represent a wide range of families of materials that varied from 0D to 3D networks: the discrete (0D) structures exemplified by metal-organic polyhedra (MOPs), cubes and nanoballs while the polymeric 1D, 2D and 3D structures exemplified by coordination polymers (CPs). Indeed, the porous 3

Dans cette thèse, de nouvelles stratégies pour la préparation de matériaux de type Metal-Organic-Frameworks (MOF) ont été étudiés et développés. L’électrodeposition bipolaire indirecte (IBED) a été utilisé pour préparer ZIF-8 et HKUST-1 sur des substrats métalliques de façon simple et avec une sélectivité spatiale. Ce concept devrait pouvoir être généralisée pour la synthèse de nombreux autres composés MOF, permettant ainsi une synthèse pas chère et verte, conduisant à de nouvelles générations de composites de type Janus basés sur des MOFs.

Abstract:
This work explores the fabrication and permeability testing of mixed matrix membranes (MMM) utilising a polymer of intrinsic microporosity (PIM-1) and various fillers. PIM-1 has been chosen for this work due to its high apparent surface area and high sorption of gases. PIM-1 also is a good candidate for gas sorption applications due to the film forming properties of the polymer. The fillers utilised in this work are Metal Organic Frameworks (MOFs) and organic cages, which have been chosen due to the gas sorption properties they exhibit. The MOFs used are micro and nanoparticles of Zeolitic Imi

Abstract:
The separation of industrially important gases into pure supplies that can be used for many practical applications is based mainly on energy intensive methods such as the cryogenic distillation which is costly and energy intensive. Therefore other routes have been introduced to industrial separation of gases such as the selective adsorption using porous solid materials. Zeolites and activated carbon are the most widely used recyclable energy-efficient porous solid materials for industrial gas separations, however the low uptake and selectivity hurdles their commercialization in some separation

Abstract:
Global warming along with the climate change derived from the World's demand for energy are among the greatest challenges to our society. To tackle climate change issue, research must focus on proposing practical approaches for carbon emissions reduction and environmental remediation. This thesis focuses on carbon dioxide separation mainly from flue gases (major sources of carbon dioxide emissions) using metal organic frameworks (MOFs) to reduce its impact on the global warming hence the climate change.
