Повний текст джерелаIn this thesis, iterative syntheses of sequence-controlled oligonylons and oligo(triazole-amide)s by protecting group-free approaches have been described. Oligonylons have been prepared by an «AA+BB» approach i.e. by stepwise couplings of a large excess of diacids (AA) and diamines (BB) monomers. This strategy was interesting but could not prevent the formation of bridged molecules. Therefore, an «AB+CD» strategy has been adopted for the synthesis of oligo(triazole-amide)s. In this case, the growth of oligomers was controlled by consecutive chemoselective couplings of AB (A = acid, B = alkyne) and CD (C = amine, D = azide) monomers. This approach was found to be efficient for the preparation of encoded monodisperse oligo(triazole-amide)s whose sequence is based on a binary code (0, 1). However, this iterative approach is slow and is not adapted to longer sequences. Consequently, a strategy based on trimers couplings has been developed in order to simplify the process. This new approach has enabled the synthesis of long code sequences containing a molecular byte

Повний текст джерелаDuring this thesis, we have worked on the synthesis and characterization of new compounds using the porphyrin macrocycle as a starting material. The aim, after synthesis, was to study the photophysical properties of these new molecules. More precisely, we have synthesized and characterized three groups of fluorenyl-porphyrin dendrimers and two oligomers in conjugated structures. Their correlation on optical property-structure have been discussed in detail, as well as the energy transfer processes from the conjugated dendron donor to porphyrin acceptor. In the first chapter, we introduce the general background of the porphyrin chemistry based on three aspects: (i) structure, (ii) optical properties and (iii) synthetic methods. We further review prior porphyrin studies done in our group and propose new molecular designs based on these results. In the second chapter, we study the influence of substitution position and nature of the antennae on the central core. Two groups of new TPP-cored porphyrin dendrimers were synthesized according to different substituted positions on the peripheral phenyl rings: para-substituted series TPP1, TPP2 and TPP3, and meta-substituted ones TPP4, TPP5 and TPP6. All have conjugated dendrons with bridged phenyl-alkynyl and are terminated by fluorenyl groups. In the third chapter, we study the influence of positions of light absorbers. To this aim, a series of TFP-cored porphyrin dendrimers presenting fluorenyls in conjugated dendrons on different positions is reported (core fluorenyl, bridging fluorenyl and terminal fluorenyl): TFP1, TFP2 and TFP3. The core fluorenyl mainly influences emission peaks and quantum yield, while the bridging fluorenyl and terminal fluorenyl have a large effect on the dendron absorption and on the energy transfer efficiency. Thus, for the largest dendrimer TFP3, dendron emission is not totally quenched by long distance energy transfer process when exciting the peripheral dendrons. In the fourth chapter, we study the influence of linkages in the Dendron. Thus, two new porphyrin dendrimers with bridged vinyl, TPP-D and TFP-D, were synthesized and compared to analogues with alkynyl bridged TPP-T and TFP-T. Vinyl and alkynyl bridges are shown to influence the optical properties of the porphyrin dendrimers to a certain extent depending on the substituted positions. Finally, in the last chapter, two oligomers with n-butyl substituted TFP as terminal group, a linear dimer and a star – shaped trimer, were synthesized from the same porphyrin monomer

Повний текст джерелаPolyelectrolytes are water-soluble charged polymers that are ubiquitous in life science and capable of interacting with many cellular constituents. Their use in clinical trials is currently limited by a lack of reliable data on the relationships linking their structures to bioproperties. This project is part of a larger program aimed at obtaining a library of well-characterized multifunctionalized polyelectrolytes for the screening of bioproperties. In this framework, we aimed at synthesizing macromolecular chains containing malonic units C(COOH)2 located at various positions alongside the polymer backbone. These units can be used as starting points to introduce several other functional groups using many reactions from organic chemistry, leading to a great number of structures from a common skeleton, including copolymers. This thesis is schematically divided into four parts: (a) a bibliographical presentation of the relationships existing between structures and properties for multifunctional polymers, followed by a more specific analysis on the importance of carboxylic esters positioning alongside a carbon chain backbone, (b) a description of experimental efforts aimed at obtaining poly(trimethylene-1,1-dicarboxylate)s, key intermediates in the synthesis of a large family of polymers described in the next chapters, (c) a depiction of the hydrolysis of the above precursor, yielding poly(trimethylene-1,1-dicarboxylic acid), as well as of the properties and reactivity of this polyacid, (d) a detailed report on the synthesis of poly(trimethylenecarboxylic acid) via the quantitative decarboxylation of the above polyacid, as well as of the properties and reactivity of this polyacid. A special focus is made in the last two sections on the scope and limitations of various post-functionalizing procedures when attempting to obtain a large library of functional polymers from polycarboxylic precursors

Повний текст джерелаThis thesis deals with the synthesis of new organicmaterials for electronic applications. Several new ring-formingmethods are employed to construct sulphur heterocycles: Tandemelectrophilic aromatic substitution and acid-catalyzedtransetherification of methoxythiophene, double electrophilicaromatic substitutions with ethane-1, 2-disulphenyl chloride,and also, the reaction of dienes with sulphur dichloride. Twonew condensed thiophenes have been incorporated in end-cappedoligothiophenes. An improvement of the synthesis of [3,2-b:2, 3-d]thiophene is reported, with some attempts toincorporate it in oligomers. A synthesis of substitutednaphthalenes is also described. A new method of producingdisubstituted thiophenes from substituted butadienes anssulphur dichloride is employed in a new route to 3, 4-ethylenedioxythiophene, a very important monomer for conductingpolymers.

Повний текст джерелаThis thesis is part of a project of the National Research Agency (ANR) which involved two companies and two university laboratories. The objective of this project is to improve the mechanical properties (abrasion resistance) and thermal (degradation temperature) nonstick fluorinated coatings by incorporating silica nanoparticles. However, silica is a hydrophilic filler which is hardly dispersed in a fluoridated matrix. Therefore, we planned to modify its surface with fluorinated reagents, and the nature of various precursors has an influence on improving the nanoparticles dispersion. Thus, we, as a first chapter, studied the miscibility and compatibility of the fluoropolymers. Fluoropolymers are known for their very attractive properties like chemical inertness, hydrophobicity and thermal. But these very good properties of fluoropolymers sometimes cause difficulties application, we chose to work with two fluorinated copolymers, poly (TFE-co-HFP), a copolymer based on tetrafluoroethylene (TFE,-CF2-CF2-) and hexafluoropropylene (HFP,-CF(CF3)-CF2-) neighbor of PTFE used for coatings, and poly (VDF-co-HFP), a copolymer composed of vinylidene fluoride (VDF, -CH2-CF2) and hexafluoropropylene. They have good properties and are easy to use in blend due to their low melting temperatures (140 and 275° C for poly (VDF-co-HFP) and poly (TFE-co-HFP), respectively). Blends have been realized and characterized between two semi-crystalline copolymers but also with a fluorinated polyether composed of several units of hexafluoropropylene oxide (HFPO,-CF(CF3)CF2O-) which is completely amorphous. The results obtained from these blends indicated that the three types of precursors can be used for fluorinated surface modifications and in function of the fluoropolymer : compounds are based on TFE (-CF2-CF2-), VDF (-CH2-CF2-) and HFPO (-CF(CF3)CF2O-). Thus, in the second chapter, the synthesis of these fluorinated precursors containing VDF and HFPO units are shown for this, two polymerization methods were carried out : 1) The iodine transfer polymerization (ITP) of VDF ; 2) The anionic polymerization by ring opening of HFPO. These products were characterized by 19F and 1H NMR spectroscopy, FTIR, GPC, XRD, TGA and DSC. Oligomers of the TFE (CnF2n+1-I or CnF2n+1-C2H4-SH with n = 4 or 6) have not been prepared because of the risks incurred during the handling of TFE (explosive gas). After their synthesis, functionalization and characterization, we have grafted them on the surface of silica nanoparticles. The main method used is the "grafting onto" which allows to modify the surface of inorganic particles with macromolecules (oligomers or polymers) and the third chapter presents three methods of grafting : 1) The radical addition of RFI and/or RFC2H4SH on a double bond (vinyl or allyl) ; 2) The condensation of an oligomer based HFPO functionalized methyl ester on a silica with amine functions ; 3) The most commonly used hydrolysis-condensation, using oligo (HFPO) functionalized alkoxysilane. The analysis methods used to characterize these fluorinated nanohybrids are the 1H and 29Si solid state NMR, FTIR, elemental and thermogravimetric analysis. We used these different surface modification to obtain a wide range of modified silica with fluorinated groups. After their characterization, these fluorinated silica are introduced by blend into two fluorinated matrices poly (VDF-co-HFP) and poly (TFE-co-HFP). The fourth is dedicated to the study of nanocomposite poly (VDF-co-HFP) / silica. Initially, a state of the art is presented as this type of composite has been widely discussed in the literature contrary to nanocomposites poly (VDF-co-HFP) or poly (TFE-co-HFP) with fluorinated nanoparticles
