Der volle Inhalt der QuelleThis work concerns the development and the study of the properties of new linear conjugated systems (LCS) built with 3,4-ethylenedioxythiophenes (EDOT) moieties. The synthesis of oligomers varying by their length, the number and the position of the EDOT units in the conjugated chain is described. The analysis of the optical and electrochemical properties clearly shows a marked influence of the EDOT unit on the structure of oligomers. The donor effect of the ethylenedioxy group increases the level of the HOMO and contributes to locate the positive charge on the EDOT moieties. A rigidification of the molecules, by intramolecular interactions between oxygen atoms of ethylenedioxy group and the sulphur atoms of an adjacent thiophene cycle, is observed. The last part proposes two alternatives for replacing the EDOT core, its sulphur analogue, EDST, and the3,6-dimethoxy-thienothiophene, which constitute interesting ways to obtain low gap polymers more soluble than the PEDOT

Der volle Inhalt der QuelleNew conjugated polymers containing separated para-phenylenevinylene-type chromophores have been synthesized via Wittig and Knoevenagel polycondensations using bisphenols-derived monomers. The structures of polymers were confirmed by NMR and FT-IR spectroscopies and their average molecular weights were determined by SEC and NMR ¹H. Thèse macromolecular materials are fully soluble in chloroform and exhibit a good thermal stability. The optical properties of the photoluminescents polymers were investigated in dilute solution and as thin films, and some structure-properties correlations have been established, mainly concerning the effects of spacer group nature, of side-chain structure and incorporation of cyano groups. HOMO and LUMO energy levels were estimated by cyclic voltametry and showed a p-type semi-conducting character for ail polymers. Single-layer diodes, based on these polymers as electro-active materials, bas been fabricated and showed relatively low turn-on voltages. As first application, two multi-layer electroluminescent diodes were elaborate and a green-light emission was obtained

Der volle Inhalt der QuelleNew advanced organic materials combining the fullerene C60 with p-conjugated oligophenylenevinylene (OPV) have been prepared. Two different approaches have been developed. A polymer approach: the synthesis of two monomers, one bearing a fullerene moiety and the other an OPV subunit, has been achieved. Their polymerization led to the following materials: a) fullerene-rich polyesters with a controlled molecular structure; b) OPV-containing polyesters with mesomorphic properties; c) polyesters containing C60 groups and OPV subunits. The latter polyesters combining the two electro- and photo-active units have been used for the preparation of solar cells. A dendrimer approach: fullerene-substituted dendritic branches have been prepared and attached to an OPV core unit. A dendritic effect has been observed for this series of dendrimers. In particular, a progressive shielding of the OPV core has been evidenced when the size of the dendritic branches is increased

Der volle Inhalt der QuelleIn this work, synthesis and characterizations of new conjugated polymers are described.These polymers, developed for their integration into devices, have been synthesized via transitionmetalfree polymerizations. Carbazole based polyazomethines have been synthesized via polycondensation reactions between di-substituted carbazoles, bearing amino and formyl functionsin positions 3,6 or 2,7. Optical and electronical properties of such polymers have been studieddepending of the linkage position. A comonomer EDOT has then been integrated into the polymer chain, and impact of such insertion has been studied. Squaric and croconic acid base polymers have also been synthesized. By varying polymerization conditions, optoelectronic properties have been tuned, leading to the formation of polymers exhibiting a white emission. These polymers have then been integrated into OLED, as the active layer. Finally, more original polymers have been synthesized, using more original reactions or monomers such as by forming in situ benzobisthiazole. Other polymers integrating more originals monomers, such a tetrazine or divanillin, have been synthesized. Optoelectronic properties of such materials have been studied for the purpose of their integration into devices
Vijayakumar, Vishnu. „Highly oriented conducting polythiophene films for thermoelectric applications“. Thesis, Strasbourg, 2020. http://www.theses.fr/2020STRAE004.
Der volle Inhalt der QuelleThe aim of this thesis is to develop new polymeric thermoelectric (TE) materials based on oriented polythiophene (PBTTT) films. High-temperature rubbing produces oriented films of controlled orientation and crystallinity. Various doping methods with suitable dopants (F4TCNQ, F6TCNNQ and FeCl3) produced enhanced TE properties along the rubbing direction. A combination of polarized UV-Vis-NIR spectroscopy and TEM uncovered the amount and orientation of dopants intercalated in the crystals of PBTTT. The diffusion coefficient of dopants is correlated to the length of alkyl side chains : PBTTT with C12 side chains shows the best TE properties because of a fast and effective diffusion of dopants in the polymer films. Finally, we evaluated the impact of dopant (geometry, electronegativity) on the TE properties. Doping oriented PBTTT with FeCl3 helped reach record electrical conductivity of 2×105 S/cm and TE power factors of 1 mW/mK2

Der volle Inhalt der QuelleThis PhD thesis aims at the design, the synthesis and the characterization of new π-conjugated polymers for OFET or OLED applications. More precisely, the first objective is to prepare two side chain liquid crystalline π-conjugated polymers, namely Polythiophene-oxa and PBTTT-Tri, which can self-organize to ordered nanostructures and exhibit p-type conduction. The second objective is to explore 2 families of novel D-A polymers expected to exhibit TADF feature: one family includes two linear TADF polymers (S1, S2) based on a carbazole- or acridan-based donor backbone and acceptor moieties (such as dicyano-benzene or cyano-pyrimidine) as side groups. The other family includes two new series of vinyl polymers (S3, S4) based on through-space conjugation between the same donor and acceptor units as those used in the first family. The photophysical properties in both solution and solid state have been performed to determine if they are TADF or not
