Texte intégralThe accumulation of persistent compounds in biota creates environmental, health and regulatory concerns. Among these substances, the poly-fluorinated compounds (PFASs) represents a case of interest due to their specific physicochemical properties. So the PFAs behavior in the environment is difficult to predict as the existing tools are not suitable. Athough it is recognized that these compounds are persistent and accumulate in biota, many knowledge gaps remain, including the mechanisms of sediment-biota transfer and the factors that control them. This thesis examines the role of sediment in the accumulation process, especially (a) exposure routes of biota, (b) role of biodiversity in the accumulation, by exposing two benthic invertebrates (Chironomus riparius and Gammarus sp.) to natural sediment. The description of PFASs kinetics of accumulation and elimination have showed the biodisponibility of the compounds to organisms. Thus, a bioaccumulation model including the organisms growth and the specificity of the compounds was used to estimate the accumulation and depuration rate constants (ku and ke). A conceptual representation of compounds transfer allowed us to understand the major routes for organisms contamination. Moreover, the interspecific variability has been assessed by comparing the PFASs bioaccumulation and transfer pathways for both invertebrates. This thesis have helped to open up many issues, and especially the influence of both biofilm and organism bioturbation onPFASs bioaccumulation. Moreover some new perspectives on the study of biomagnification were opened

Texte intégralA lot of studies showing the water-repellency of fluorine-containing polyacrylates were reported since 1950. A string connection between these surface properties and the structure of the polymers (bilayer organization of the perfluorinated lateral chains) has been demonstrated. The purpose of this work is the synthesis and the polymerization of new functionalized fluorine-containing acrylic monomers. Then physical and chemical properties of these compounds are investigated. In a firt part, we describe the synthesis of acrylic monomers bearing different kind of organic group (mesogenic group). Particularly, we investigate the free radical addition of perfluorinated mercaptans to [omega]-unsaturated alcohols and the Fisher esterification of β-hydroxyl sulfide with acrylic acid. In second part, the homopolymerization and copolymerization of the previous monomers is studied. Then, the results of physical and chemical properties determinations are detailed. The investigation of the changes of the thermal, strutural and surface properties of [omega]-perfluorooctyl-alkyl acrylates with the increasing of the number of methylen group into the lateral chains, shows an even-odd effect. Structural and thermal properties of fluorine-containing polyacrylates can be increased significantly by adding an organic group into the lateral chain. The mesogenic group effet of these moieties is demonstrated. Finally, a sulfonated monomer is copolymerized with butyl acrylate in one hand and in second with stearyl crylate. The two copolymers water-repellencies are investigated and compared to commercial compounds. The good results obtained and the quite simple synthesis of this monomer, afford a possible commercial use

Texte intégralThe development of methodologies to easily functionalize surfaces is a fast growing field. We have synthesized and characterized new highly fluorophilic copper(II)-carboxylate complexes that have been employed to modify surfaces. In the solid state, these complexes exhibit a high affinity for water, the hydration process inducing dramatic modifications of their magnetic properties. These fluorophilic complexes are strongly adsorbed on teflon or glass to afford hydrophilic and coordinating surfaces. Using coordination chemistry, the surfaces can than be functionalized. Porphyrins monolayers and thin layers have been prepared on glass and teflon and characterized, in particular by their optical properties

Texte intégralThe results reported in this thesis contribute to a better understanding of the tropospheric fate of VOCs belonging to two families, nitrogen containing and fluorinated compounds. The work has been conducted in different laboratories (LCSR, University of Wuppertal, JRC and EUPHORE). The experimental techniques used are UV-Visible absorption, pulsed laser photolysis-laser induced fluorescence (PLP-LIF) and smog chambers. Height nitrogen containing compounds have been investigated: one amine (JV-methyl pyrrolidine, NMPL), five amides (N-methyl formamide, MF ; JV. JV-dimethyl formamide, DMF ; jV. TV-dimemyl acetamide, DMA ; A/-methyl pyrrolidone, NMP and jV-formyl pyrrolidine, FPL) and two imides (N-methylsuccinimide, NMS and Af-formylpyrrolidone, FP). The second part of this work aimed at better defining the atmospheric degradation processes of perfluorinated compounds, fluorotelomer alcohols and perfluorinated aldehydes. The results obtained show a reduction of the strength of this potential source in the atmosphère of the toxic and persistant perfluorinated carboxylic acids

Texte intégralThe presented research represents a comprehensive exploration of phosphorhydrazone (PPH) dendrimers, delving into their synthesis, functionalization, and catalytic applications, with a specific focus on para-substituted phenols for surface functionalization. The synthesis process entails a meticulous two-step reaction sequence, initiating from chlorinated phosphorus atoms in the core and progressing through substitution with 4-hydroxybenzaldehyde, ultimately culminating in dendrimer generation through condensation with MMHP(S)Cl2. To enable subsequent metal introduction were synthesized different phenolic derivates, alongside a model molecule designed to emulate iminophosphine reactivity while addressing phosphine oxidation concerns. The synthesis of bidentate phenols was described in detail, emphasizing the challenges faced and optimizations made, with a particular focus on the scalability of the procedures. The research also explores the modification of dendrimer surfaces to enhance solubility, with a specific emphasis on integrating perfluorinated ligands. Despite challenges in overall yield, alternative synthetic pathways were considered, resulting in the successful synthesis of phenols functionalized in the para position with alkylpolyfluorinated chains of varying lengths. Moving on to the characterization of PPH dendrimers, the study begins with the preparation of (1-methylhydrazineyl)phosphonothioic dichloride (MMHP(S)Cl2). Model molecules were synthesized to simulate PPH dendrimer surfaces, progressing to higher dendrimer generations. Distinctive features of PPH dendrimers, including their identification through 31P-NMR, were highlighted. A significant challenge in this phase involved ensuring the scalability of PPH dendrimer synthesis, which was successfully overcome. The research then shifts its focus to the precise functionalization of PPH dendrimers with previously synthesized phenolic substituents. The objective was to minimize di-symmetric substitution during the precise di-functionalization of the P(S)Cl2 function. Catalyst synthesis involved ligands with metal complexation for stability. Both precisely and stochastically substituted PPH dendrimers were successfully scaled up to the gram scale. In the final segment, the research delves into the catalytic activity of dendrimeric catalysts in various coupling reactions, both in organic and non-conventional solvents. Stille cross-coupling, Heck cross-coupling, and Suzuki coupling reactions were explored. The dendrimeric catalyst exhibited heightened activity in the Stille cross-coupling, showcasing a positive multivalence and generation dendritic effect. Despite insolubility in scCO2, the catalyst demonstrated activity for the Stille cross-coupling in heterogeneous conditions, emphasizing a positive generation dendritic effect. Additionally, the dendrimeric catalyst showed activity for the Heck cross-coupling in a biphasic fluorous/organic system. The study also addresses challenges associated with catalyst recovery in both organic and non-conventional solvents. Comparisons between precisely and stochastically difunctionalized dendrimers underscore positive multivalence and generation dendritic effects in specific reactions. Notably, higher activity of precisely substituted dendrimers from generation 1 to 3 compared to stochastically substituted homologues was demonstrated in the Stille cross-coupling. In summary, this research provides a thorough examination of dendrimer synthesis, functionalization, and catalytic applications, offering valuable insights and suggesting avenues for future refinement in sustainable catalytic processes

Texte intégralThe first part of the manuscript describes the still underdeveloped chemistry of the heavier Alkaline-Earths (Ae): Ca, Sr and Ba. Catalytic applications of homoleptic and heteroleptic complexes of Ae have been investigated in the last years, heteroleptic complexes being more efficient in the control of the catalytic process. Unfortunatelly, heteroleptic complexes often rearrange to homoleptic towards the Schlenk equilibrium, which can be prevented by chelating, steric stabilizing ligands. Large, electron-withdrawing highly fluorinated tris(indazolyl)borate ligands (TpF) provide the desired steric protection, enhancing at the same time the catalytic activity in the hydroamination of aminoalkenes. Chapter 1 describes homoleptic and heteroleptic complexes TpF 2Ca and TpF CaI with the aim of chosing the adapted ligand. Several heteroleptic silylamido complexes of the formula TpF Ae-N(SiMe2R)2 (Ae = Ca, Sr ; R = Me, H), precatalyst of hydroamination of aminoalkenes have been studied in Chapter 2. The structures often showed interesting agostic interactions. TpF Ca-N(SiMe3)2 is one of the most active precatalyst in cyclohydroamination. Organocalcium compounds containing Ca-alkyl bonds are a rare family. Only a few heteroleptic complexes TpFCa-R (R = alkyl) have been described. Two examples are described in Chapter 3. The second part of the manuscript contains a reactivity study of dicyclopropylzirconocene Cp2Zr(c-C3H5)2 towards small heteroaromatic cycles. C-H bond activation of furan and thiophene, dearomatization of pyridine and C-F bond activation of pentafluoropyridine result from the initial formation of a Eta2-cyclopropene intermediate. Mechanistic investigations through kinetics and DFT calculations are provided

Texte intégralPerfluorinated compounds (PFCs) is a collective name for fluorinated surfactants and polymers with the general structure CF3-(CF2)n-SO3- (sulfonates) or CF3-(CF2)n-1-CO2- .(acids). This group is characterized by a high persistence, bioaccumulation and long term toxicity which are rising environmental and public health concerns. In the present work, we analyzed the in vitro carcinogenic potential of the two major PFCs, perfluorooctane sulfonate (PFOS), and perfluorooctanoic acid (PFOA), and their substitute, perfluorobutane sulfonate (PFBS). Cell transformation assays were carried out on Syrian hamster embryo (SHE) cells in a 7 day-treatment using the standard and the initiation-promotion protocols. Genotoxicity was tested using the comet assay. PFOS was not genotoxic on SHE cells, but it induced cell transformation at non cytotoxic concentrations 0,37 and 3,7 µM (p<=0,01). These concentrations coincided with serum PFOS concentrations measured in occupationally exposed workers. An increased expression of PPARs was registered after 7 days. The ppar-beta/gamma mRNA appeared to increase rapidly (24 hours after PFOS treatment) at concentrations closely related to cell transformation (p<=0,05). PFOA was inactive alone, but induced cell transformation of SHE cells pre-initiated with benzo(a)pyrene (BaP). Therefore PFOA was shown to act as a tumor promoter and a non genotoxic carcinogen at a large range of concentrations (3,7 x 10-4 à 37 µM). This range of concentrations covered seric concentrations in non-occupationally exposed and occupationally exposed populations. PFBS was negative alone and on BaP-pretreated SHE cells. For this reason, its use as a substitute for PFOS appears to be justified. To conclude, the cell transforming potenty of PFOS and PFOA denotes in vitro carcinogenic potential. Consequently, the hypothesis of their implication in human cancer recorded in occupationally exposed populations cannot be ruled out

Texte intégralContext. Although traditional foods play a central role in Indigenous Peoples nutrition and culture, their intake is increasingly being replaced by processed foods, particularly among younger generations. Other than their lower nutritional quality, processed foods may also contain chemical contaminants from food processing and packaging that are known or suspected endocrine disruptors, such as perfluoroalkyl acids (PFAAs) and bisphenol A (BPA). In 2015, the project Jeunes, Environnement et Santé / Youth, Environment and Health (JES!-YEH!) was conducted among children and youth (3-19y) in collaboration with four First Nation communities in Quebec (n=198) and the objectives of the present project were to: (i) Document exposure to PFAAs and BPA in comparison to the most recent youth data of the Canadian Health Measures Survey (CHMS Cycle 5 2016-2017); (ii) Describe the intake of different food categories that may contain PFAAs or BPA; and (iii) Examine the associations between food categories intakes and exposure to these contaminants. Methods. Anthropometric measurements were taken and questionnaires were administered, including a food frequency questionnaire, based on which food intakes were calculated. Biological samples were collected, and serum was analysed for PFAAs (PFOS, PFOA, PFHxS, PFNA) and urine for BPA. Generalized linear models were used to test associations between food intakes and biomarkers of exposure to PFAAs and BPA. Results. Mean PFNA serum concentrations were significantly higher than in the CHMS Cycle 5 (2016-2017) for the same age groups among Anishinabe participants, where as concentrations of mean PFOS, PFOA and PFHxS levels were lower than CHMS values among all JES!-YEH! participants. Mean urinary BPA concentrations were also higher than in the CHMS Cycle 5 (2016-2017) in all participants. Dairy products intake was high in comparison to other food categories, and especially milk, among Anishinabe participants aged 6 to 11 years old and Innu participants aged 3 to 5 and 6 to 11 years old. Total dairy products intake was significantly associated with PFNA serum concentrations among Anishinabe participants and Innu participants. PFNA was likewise associated with ultraprocessed foods intakes among Anishinabe participants, whereas it was associated with wild marine fish and berries intakes among Innu participants. PFHxS was associated with microwave popcorn intake among Anishinabe participants. For BPA, a positive association was found with cheese and milk intakes in Anishinabe participants, and with wild marine fish, wild berries, desserts and processed meats intakes in Innu participants. Conclusion. These results highlight the importance of better documenting food-processing and packaging methods, particularly for dairy products, and their contribution to endocrine disruptors exposures as well as to promote minimally processed and unpackaged foods to provide healthier food environments for youth in Indigenous communities and beyond.

Texte intégralFluorine atom is essential in our everyday life. It is necessary for the development of battery, refrigeration (Fréon), liquid crystals which constitute the screens of phones, or materials (Téflon®). But its main role is in life sciences. The introduction of a fluorine atom modifies the physical and chemical properties of organic molecules, allowing to modulate and to enhance their biological activities. Its introduction in organic molecules constitutes a key challenge for chemists, which necessitates continually the development of new reagents for fluoration or perfluoroalkylation reactions. Among these, perfluorinated sulfoximines are electrophilic, nucleophilic or radical perfluoroalkylating reagents. Moreover, perfluorinated sulfoximines have peculiar properties with uses in material or life sciences.My PhD work falls within the project of our laboratory to develop a new general acces to perfluorinated sulfoximines and the synthesis of highly functionalized sulfoximines. My PhD work also deals with the synthesis of sulfilimino iminiums, derived from sulfoximines, which are efficient and versatile reagents for visible light-induced perfluoroalkylation reactions

Texte intégralCurrently , the molds used for making aircraft composite piecess are made of metal alloys ( FeNi Invar ) popular for their low coefficient of expansion. However, these alloys have several drawbacks ( weight, price , delivery time ) which encourage manufacturers to rotate to other materials. In this context, the epoxy composites / carbon fibers are an interesting altemative given their mechanical properties similar to Invar while combining lightness and ease of implementation . However , with such molds, phenomena of adhesion may occur between the infused epoxy resin constituting the future piece , and the mold itself made of an epoxy resin. Their close nature promotes diffusion phenomena or molecular interactions involved in the adhesion of polymers.The works presented in this thesis is therefore to minimize all phenomena promoting the adhesion between two epoxy resins (one being cured in contact with the second). To do this, the work is focused on sustainable change in the physicochemistry and the surface topography of the epoxy resin component mold. These two parameters are indeed identified as essential for obtaining surfaces prerequisited low wetting character , for good adhesion with a third body. At first , the physicochemistry of the resin surface of the mold was permanently changed using a fluorinated additive grafted beforehand on the epoxy resin. The mechanism of fluorination of the surface has been studied and a critical step in migration of the fluorinated additive towards the air / resin interface during curing has been identified. In a second step , a controlled micrometer scale roughness is applied to the surface of the resin as amended . The surface properties arising are studied and show an accentuation of low wetting character of fluorinated resins . Finally, the properties of interfaces between the modified epoxy resins constituting the mold and blank epoxy resin representing a molded part are studied via a mechanical test. The results obtained ( strength and type of failure ) are put in contact with the surface of the modified epoxy resin properties
