Guillerm, Vincent. "Synthèse, fonctionnalisation et propriétés d'adsorption de nouveaux solides hybrides poreux". Versailles-St Quentin en Yvelines, 2011. http://www.theses.fr/2011VERS0001.
Texto completo da fontePorous hybrid solids are intensively studied, and are of a growing interest, due to their polyfunctionality, for several field for their potential applications in catalysis, adsorption/storage/separation, optical properties, drug release, etc. The bibliographic part of this thesis summarizes the main concepts related to Metal-Organic Frameworks (MOFs), with a particular interest in tetravalent metal chemistry (zirconium, titanium) and polycarboxylate based MOFs, as well as their functionalization and their sorption properties. The second part deals with the study of a series of functionalized « flexible » MOFs (belonging to the MIL-53(Cr) structure type), using organic groups exhibiting different polarities. This study goes from the synthesis to the gas sorption properties (CO2, CH4). The next chapter is looking toward MOFs synthesis using zirconium and titanium, which were up to now scarcely used in the field of MOFs. In the same way than previously, a large series of functionalized UiO-66 solids were studied, as well as few extended analogues, as well as an unprecedented isoreticular series of zirconium carboxylates, labeled MIL-140. A particular interest is here given to the comparison of these two series, both in term of hydrothermal and mechanical stabilities, which are of outmost importance for most of the industrial applications, but also in term of gas sorption properties (N2, CO2, CH4, H2S). Finally, several large scale syntheses of known or new MOFs have been performed, so that these compounds could be provided to few collaborators. Their published results have been inserted in this chapter

Texto completo da fonteThis thesis focuses on the synthesis and crystal-chemistry characterization of hybrid materials combining a dicarboxylate organic framework and a mineral component (3d and/or 4f ions). A novel divalent iron oxalate, [NH4]2[FeII(C2O4)2]·H2O, obtained by solvent-free synthesis is presented. Its crystal structure is resolved and described from both single crystal and powder X-ray diffraction. It is an orthorhombic structure with a marked two-dimensional character which contains two sites for ferrous ions. Magnetic and Mössbauer 57Fe spectrometry measurements complete and confirm these results. A large family of new compounds, of general formula Ln2(C8H6O4)3(NMF)4.xH2O.yNMF (Ln = Pr, Nd, Sm, Eu, Gd, Dy and Er), based on the terephthalate ligand and 4f ions, is then described. Depending on the size of the 4f ion and temperature of synthesis, three different crystalline structures have been revealed. These compounds were synthesized by the hydrothermal method at temperatures of 120°C and 150°C, using the solvent N-MethylFormamide (NMF), rarely used in the synthesis of hybrid materials based on 4f ions. Depending on the structural type adopted, the 4f ions associate in dimers, in pseudo-dimers or form chains. The association of 3d and 4f ions under similar synthesis conditions led to a three-dimensional assembly in LnMn3(1,4-bdc)4(form)2(NMF)2·Hma compounds. The crystallographic characterization was carried out using X-ray diffraction measurements (single crystal and powder), supplemented by thermogravimetric measurements. Special attention was paid to the completion of the study of the compound Mn3(OH)2(C6H2O4S)2. The preparation of samples in anaerobic conditions, purer than those of previous works, made possible neutron diffraction measurements (PSI, Switzerland) and the determination of the magnetic structure. We show that the antiferromagnetic structure of Mn3(OH)2(C6H2O4S)2 is closely related to that of Mn2(OH)2(C8H4O4)

Texto completo da fonteThermoelectric systems allow for the direct and reversible conversion of a temperature difference into electricity. Doped semiconductors allow to obtain effective systems for a substantial difference of temperature, nevertheless they are limited to niche applications. Bi2Te3, the reference material for applications close to room temperature is, in addition, toxic and costly. Electron conducting polymers represent an alternative for low temperature thermoelectric devices rince they are flexible, light and cost¬effective, however their performance is still too low for large scale development. The objective of this thesis was to develop hybrid materials with a good control of the inorganic-organic interface in order to take advantage of both components and prepare materials with enhanced thermoelectric properties. To achieve this objective, Bi2Te3 doped with Se, S or Sb nanoparticles were synthesized using a soft chemistry route. Their mechanisms of formation in the presence of different additives have been studied and different compositions and morphologies have been obtained. Oligothiophenes molecules functionalized with thiols functions were then prepared and further grafted at the surface of synthesized nanomaterials. Finally, hybrid materials were obtained either by dispersing grafted particles into a conducting polymer matrix, or by chemical or electrochemical co-polymerization of the grafted monomer with a monomer in solution. The use of grafted particles lead to a better dispersion of the inorganic material in the polymer matrix compared to bare particles

Texto completo da fonteGlobal warming is one of the main concerns in our society nowadays, year after year the impact and consequences are becoming more visible. The Paris agreement set a target to limit the CO2 emission, which is mainly caused from the increasing demand for energy based on fossil fuels. Since then, the scientific community has increased their efforts on looking for clean energy sources such as renewable energies. In this regard, solar energy is meant to be one of the main energy sources that could replace fossil fuels. Therefore, photovoltaic technologies have evolved tremendously and, organic-inorganic hybrid halide perovskite materials have been one of the technologies with the fastest growth in solar cell performance. Perovskite materials possess unique properties such as flexibility, low-cost and ease to manufacture. Nonetheless, there are still some issues regarding their stability against atmospheric conditions that need to be understood. This dissertation focuses on the characterization of the electrical properties at the nanoscale of perovskite-based thin films by means of scanning probe microscopies (Conducting AFM, Kelvin Probe Force Microscopy, and Scanning Microwave Microscopy).In this growing field of research, many perovskite structures, deposition methods, and synthesis routes have been developed and introduced in perovskite-based solar cells. In the first part of this dissertation, the context of perovskite materials is detailed and the methodology used through the thesis is also described. Then, we study and compare the electronic properties at the surface of perovskite materials synthesized following two different routes. Moreover, it is known that device engineering can increase both, the performance, and the stability of perovskite solar cells. In a second part if the thesis, we show that for a given perovskite structure, the stability upon exposure to controlled small amounts of water can be significantly improved through the synthesis optimization. Finally, we provide a series of conclusions and perspectives that could help to further understand the perovskite behaviour at the local scale and to improve the cell performances

Texto completo da fonteOn a global scale, the share of renewable energies in the energy mix is constantly increasing. Based on the principle of photosynthesis, Dye-Sensitized Solar Cells are an emerging technology for Building Integration Photovoltaic (BIPV). These hybrid cells use an inorganic semiconductor oxide whose surface is covered with an organic dye. The absorption of the incident light by this dye will cause the injection of an electron from the photo-excited state of the molecule into the conduction band of the oxide. A redox mediator present in the electrolyte will regenerate the oxidized dye and generate a current under illumination. The dyes already described in the literature shows efficiencies reaching 14%. On the other hand, very few of these materials can absorb up to the near infrared range (NIR) (700-1000 nm). Thereby, the absorption of the NIR spectral range could lead to a greater photo-generated current density. In this context, this work presents a complete study of new panchromatic dyes extending into the near infrared range. For this study, the "donor-acceptor" approach was used to obtain the desired optoelectronic properties. A first family based on benzothiadiazole derivatives has been developed leading to very good absorption properties in the NIR region (absorption up to 925 nm). The optical, electrochemical and photovoltaic properties of these materials have been studied in order to understand the limitations for solar cell applications. Following this, a new dye family based on isoindigo derivatives was synthesized and studied by UV-Visible spectroscopy, electrochemistry and DFT simulation. These compounds strongly absorbs in the UV-visible and NIR spectral range up to 848 nm. The dyeing bath composition and the electrolyte formulation were optimized in order to obtain a device conversion efficiency of 5.76%. Photophysical measurements have allowed us to have a fine understanding of the limiting factors of these dyes. On the basis of this observation, we improved the structure of one of the dye and witg this new molecule we reached a power conversion efficiency of 7.0% with a UV-Visible and near infrared absorption for the solar cell. In the last part of this work we have also obtained preliminary results employing various alternative materials to the TiO2/iodine system

Texto completo da fontePhotoluminescent materials are playing a major role in applications related to photonics, optoelectronics or lighting. Combining them with polymers allows the design of easy-to-shape-functional materials with enhanced application versatility. Related to this, hybrid materials composed of an organic polymer matrix containing strongly luminescent octahedral metal clusters were prepared. Octahedral metal clusters have several advantages: a deep luminescence in the red and the near-IR region, a high quantum yield, a large Stokes shift and no photobleaching or photoblinking effects. As organic host matrices, PMMA and PDMS were used because of their optical and mechanical properties in addition to their thermal stability. However, a prerequisite for realizing hybrid materials is to homogeneously introduce the ceramic inorganic emitter in the organic polymer to avoid segregation-phase phenomena. For this purpose, several integration approaches were developed to prepare new hybrid materials. Meanwhile, spectroscopic analysis were performed on these hybrids demonstrating their huge potential. Actually, these hybrids were used to design a self-erasable inkless light-imprinting material when the hybrid is combined with an organic fluorophore, and 1D- and 2D-waveguides. The 1D-waveguides can be applied for integrated photonics while 2D-waveguides combined with liquid-crystals lead to a new luminescent PDLC (Polymer Dispersed Liquid Crystal) material for Luminescent Solar Concentrator technology

Texto completo da fonteThe aim of this work was to investigate the influence of the nanocofinement on the behaviour of organic substrates embedded in mesoporous silicas. This research hinged on two parts. The first study focused on the efficiency of the fragmentation reaction of confined alkoxyamines, under thermal or photochemical activation. Thanks to the comparison with the very same reactions in solution, the quantitative EPR measurements showed that the confinement of organic precursors had no effect on the efficiency of these reactions. Secondly, organic-inorganic hybrid materials were synthesized. These mesoporous silicas were functionalized with diazene radical precursors. Upon 360 nm irradiation, they generated heteroatomic radicals. Different materials were prepared, including one which enabled to form a face-to-face pair of different radicals, i.e. an aryloxyl radical in front of an arylsulfanyl radical. Studies carried out by continuous and pulsed wave EPR enabled to highlight the high stability of these confined paramagnetic species and to measure their relaxation times
