Texto completoEsta tesis se centra en la síntesis coloidal de nanocristales (NCs), en la exploración de su química de superficie y en su ensabanado en nanomateriales porosos funcionales. Para demostrar la versatilidad de aplicación de dichas estructuras, en este estudio se han considerado NCs de distintos tipos de materiales: metales (Au), óxidos metálicos (CeO2, TiO2, Fe2O3), calcogenuros metálicos (In2S3, ZnS, PbS, CuGaS2,Cu2ZnSnSe4) y sus materiales compuestos. El trabajo se dividió en dos bloques. En el primero se desarrolló y optimizó la síntesis de NCs de óxidos y calcogenuros metálicos y se evaluó su potencial para aplicaciones de catálisis y fotocatálisis. Se investigó en profundidad la síntesis de NCs de CeO2, poniendo énfasis en controlar su morfología. Se consiguió producir NCs de CeO2 de forma controlada (esférica, octapodo ramificado, cúbico ramificado y romboidal) y con tamaño controlado (7-45 nm). Asimismo, se obtuvieron NCs de Cu2ZnSnSe4 con una fina distribución de tamaños y composición controlada. En el segundo bloque se establecieron y estudiaron procedimientos para fabricar nanomateriales porosos mono- o multicomponentes a partir del ensamblado de NCs. Se desarrolló una estrategia basada en el ajuste de la química de superficie de NCs de óxidos metálicos (CeO2, Fe2O3,TiO2) y de calcogenuros metálicos (In2S3, CuGaS2-ZnS) que permitió su ensamblaje controlado en estructuras porosas de tipo gel y aerogel. En el caso de los óxidos metálicos, se determinó que el ensamblado se inicia con la adición de un epóxido a NCs funcionalizados con glutamina, causando la gelación. La desorción oxidativa de ligandos basada en la formación de enlaces calcogenuro-calcogenuro se propuso como mecanismo de gelación en calcogenuros mono- (In2S3) y multicomponente (CuGaS2-ZnS). Se investigó el impacto del empleo de distintos ligandos en la eficiencia foto-electrocatalítica de NCs en forma coloidal, ensamblados en geles y soportados en sustratos. Se desarrolló y estudió el ajuste de la química de superficie de NCs para la obtención de ensamblajes multicomponente mediante interacción electrostática de coloides en suspensión. El mecanismo de gelación fue investigado al detalle para materiales compuestos de NCs de oxido metálico (CeO2) con NCs de óxido de calcogenuro (PbS-CeO2) y metálicos (Au-CeO2). Los aerogeles de Au-CeO2 demostraron potencial para la oxidación de CO.

Texto completoHybrid nanoscale complexes incorporate the attributes of organic and inorganic components to yield novel multifunctional materials. Because the individual components themselves and the combinations used can be widely varied to tune the properties of the resulting complex, the potential for new properties and practical applications is nearly limitless. However, widespread use of these materials relies on appropriate design, synthesis and characterization strategies to ensure proper function and compositional integrity. This dissertation describes the chemistry of these hybrids, made possible by combining organic ligands, inorganic nanoparticles, and metal ions, and the interesting optical and spectroscopic properties associated with the hybrid nanomaterials. Organic ligands containing Bunte salt and acyclic malonamide functionalities were attached to gold nanoparticles to produce colorimetric sensors for lanthanide ion detection. Bunte salt functionality stabilizes the gold core and malonamide functionality offers selective and sensitive lanthanide ion binding. The binding interaction controls a nanoparticle cross-linking event that changes the color of the nanoparticle solution, resulting in visual, colorimetric lanthanide ion detection. Next, the concentration of malonamide ligand was diluted and replaced with a diluent ligand yielding nanoparticles stabilized with a mixed ligand composition. The mixed ligand environment makes the optical response of the colorimetric sensor reversible. Furthermore, the use of Bunte salt ligands during nanoparticle synthesis has allowed the investigation of the role of reducing agent on nanoparticle stability. In addition to exploring interactions pertaining to gold nanoparticle complexes, a new approach to sensitize europium ion luminescence was developed by fabricating a zinc oxide/europium complex. A molecular linker permits simultaneous zinc oxide nanoparticle functionalization and trivalent europium binding in order to tether the europium ion close to the nanoparticle surface. The zinc oxide nanoparticle can then act as an inorganic antenna, transferring energy to the europium ion and enhancing its luminescence. Finally, a strategy was developed to synthesize bifunctional bicyclic malonamides. Synthesis of these ligands allows the enhanced f-block ion binding affinity of bicyclic malonamides to be incorporated into functional materials to compare their performance to our previously prepared acyclic malonamide hybrid complexes. This dissertation includes my previously published and co-authored materials.

Texto completoThe immobilization of photosensitizers (PS) in nanometric materials is an excellent alternative to their use in molecular forms for photodynamic therapy (PDT). The present work describes a series of synthetic strategies for the immobilization of PS on silica nanospheres containing magnetic nucleous, as well as the studies of the photochemical, photophysical and morphological properties of the obtained materials. The studied PS were methylene blue, thionin, azure A, protoporphyrin IX, hematoporphyrin IX and chlorophyllin. The immobilization methodologies involve the addition of PS during the growth of the silica shell or the attachment of PS to the material surface. Often, a previous modification of the PS with organosilanes was necessary. The magnetic cores were prepared by co-precipitation of iron(II) and iron(III) salts in basic media and the coating with silica was performed by a microemulsion using TEOS. After coating with silica, the magnetic nanomaterial maintained the superparamagnetic behavior. The generation of singlet oxygen by thionin and methylene blue was not detect after immobilization. The generation of singlet oxygen by immobilized azure A, protoporphyrin IX and chlorophyllin was detected and characterized by chemical and physical methods. The material containing chlorophyllin is promising for PDT and was applied in preliminary studies with HeLa cells, causing cell death after irradiation. The behavior of the immobilized PS and the possible extra protection given by the silica shell were investigated by fluorescence quenching with bromide ions and by suppression of singlet oxygen generation with bovine serum albumin. Hematoporphyrin IX was more affected in the free form than immobilized in silica nanospheres, which indicates that the immobilized FS still generates singlet oxygen and is more protected against interfering species

Texto completoNew routes for low cost production of functionalized magnetic nanoparticles (MagNP) have been pursued in this Thesis, by employing environmentally compatible chemicals and resources. The nanomaterials exhibited typical superparamagnetic behavior consistent with the presence of magnetic monodomains, revealing no hysteresis above 280 K, Tb = 90 K at H = 500 Oe, and saturation magnetization as high as 90 emu g-1. The synthetic procedures were carried out using biocompatible solvents derived from biodiesel of soybean and Brazilian mamona seeds, leading to substantial reduction of cost for large-scale production. The superparamagnetic nanoparticles were initially designed for capturing, transporting and recycling chemicals or drugs, including pollutants, catalysts and enzymes, using external magnets. They provide a green alternative strategy for conventional processes that make extensive use of solvents, generate too much waste, and proceeds through highly energetic demanding steps such as centrifugation, solvent extraction and high-pressure filtration. In our work, the MagNPs were appropriately modified for working in polar and non-polar media, employing for instance, amphiphilic species for interacting with Fe3O4 using the available polar groups, and also with carbon surfaces by means of hydrophobic interactions. Accordingly, new superparamagnetic nanomaterials incorporating several types of materials carbon based. It was observed that the carbon materials containing 15 to 20% of magnetic nanoparticles could be completely removed from the media with the use of a magnet. In this way, the functionalized superparamagnetic nanoparticles proved useful for the removal of oil spills and of organic pollutants from industrial processing water, as well as for the capture, removal and recovery of metallic elements and organic species from the effluents. In addition, as a proof of concept, smart windows and displays were elaborated based on the modulation of the transmitted or reflected light by the external magnet. This work was sponsored by PETROBRÁS, and also covered missing, non-authorized aspects involved in two patent applications. Finally, an important consequence to be mentioned is the contribution of this project for launching new chemical routes towards sustainability, such as the development in this Laboratory, of green, magnetic nano-hydrometalurgy for processing and recycling strategic metals, and of the magnetic remediation of polluted environments using the functionalized nanomaterials.
