Streszczenie:
Benzo[1,2-d:4,5-d′]bis(oxazole) (BBO) is a heterocyclic aromatic ring composed of one benzene ring and two oxazole rings, which has unique advantages on the facile synthesis without any column chromatography purification, high solubility on the common organic solvents and planar fused aromatic ring structure. However, BBO conjugated building block has rarely been used to develop conjugated polymers for organic thin film transistors (OTFTs). Three BBO-based monomers, BBO without π-spacer, BBO with non-alkylated thiophene π-spacer and BBO with alkylated thiophene π-spacer, were newly synthesized and they were copolymerized with a strong electron-donating cyclopentadithiophene conjugated building block to give three p-type BBO-based polymers. The polymer containing non-alkylated thiophene π-spacer showed the highest hole mobility of 2.2 × 10−2 cm2 V−1 s−1, which was 100 times higher than the other polymers. From the 2D grazing incidence X-ray diffraction data and simulated polymeric structures, we found that the intercalation of alkyl side chains on the polymer backbones was crucial to determine the intermolecular ordering in the film states, and the introduction of non-alkylated thiophene π-spacer to polymer backbone was the most effective to promote the intercalation of alkyl side chains in the film states and hole mobility in the devices.

Streszczenie:
Graphene oxide is an imperative modified form of graphene. Similar to graphene, graphene oxide has gained vast interest for the myriad of industrial applications. Conjugated polymers or conducting polymers are well known organic materials having conducting backbone. These polymers have semiconducting nature due to π-conjugation along the main chain. Doping and modification have been used to enhance the electrical conductivity of the conjugated polymers. The nanocomposites of the conjugated polymers have been reported with the nanocarbon nanofillers including graphene oxide. This review essentially presents the structure, properties, and advancements in the field of conducting polymer/graphene oxide nanocomposites. The facile synthesis, processability, and physical properties of the polymer/graphene oxide nanocomposites have been discussed. The conjugated polymer/graphene oxide nanocomposites have essential significance for the supercapacitors, solar cells, and anti-corrosion materials. Nevertheless, the further advanced properties and technical applications of the conjugated polymer/graphene oxide nanocomposites need to be explored to overcome the challenges related to the high performance.

Streszczenie:
Les cellules solaires organiques (OSC) apparaissent comme une technologie prometteuse pour les énergies renouvelables en raison de leur poids léger, leur grande flexibilité et leur processus de fabrication peu coûteux. Jusqu'à présent, la plupart des OPV ont utilisé des dérivés de Fullerene, tels que PCBM ou PC71BM, en tant qu'accepteur d'électrons dans la couche active, qui s'est avéré être un goulet d'étranglement pour cette technologie. Par conséquent, le développement d'accepteurs non-fullerene est devenu la nouvelle force motrice de ce domaine. Les cellules solaires tout-polymères (tous-PSC) qui ont les avantages de la robustesse, de la stabilité et de l'accessibilité ont déjà atteint PCE jusqu'à 9%. Ainsi, le développement de nouveaux matériaux accepteurs est impératif pour améliorer les performances de tous les PSC
Organic solar cells (OSCs) appear as a promising technology for renewable energy owing to their light weight, great flexibility and low-cost fabrication process. So far most of the OPV shave been using fullerene derivatives, such as PCBM or PC71BM, as the electron acceptor in the active layer, which have been proven to a bottleneck for this technology. Therefore,developing non-fullerene acceptors has become the new driving force for this field. All-polymer solar cells (all-PSCs) that have the advantages of robustness, stability and tunability have already achieved PCE up to 9%. Thus, developing novel acceptor materials is imperative for improving the performance of all-PSCs

Streszczenie:
It is well established that the morphology and physical properties of an organic semiconducting (OSC) material regulate its electronic properties. However, structure-function relationships remain difficult to describe in polymer-based OSC, which are of particular interest due to their robust mechanical properties. If relationships among the molecular and bulk levels of structure can be found, they can aid in the design of improved materials. To explore and detail important structure-function relationships in polymer-based OSC, this work employs molecular dynamics (MD) simulations to study various π-conjugated polymers in different environments. Two independent investigations are discussed in this work. One investigation examines how the purposeful disruption of the π-conjugated backbone to increase the chain flexibility impacts the chain structure and packing in the condensed phase. This is done by adding a conjugation break spacer (CBS) unit of one to ten carbons in length into the monomer structure of diketopyrrolopyrrole-based polymers. It is found that trends in the folding and glass structure follow the increase and the parity (odd versus even) of the CBS length. The second investigation analyzes a variety of polymers and small molecule acceptor (SMA) blends to observe the effects of changing the shape of either component and the physical properties of the material, as well as the structure of the polymer chains. It is found that the conjugated core, the side chains, and the planarity or sphericity each influence the density and diffusion of the materials made.

Streszczenie:
Interchain interactions between π-systems have a strong effect on the properties of conjugated organic materials that find application in devices such as light emitting diodes (OLEDs), organic photovoltaics (OPVs), and field effect transistors (FETs). We have prepared covalently-stacked oligo(1,4-phenylene ethynylene)s and oligo(1,4-phenylene vinylene)s to study the influence of chain-chain interactions on the electronic structure of closely packed conjugated units. These serve as models for segments of conjugated materials in thin film devices. Extension of this concept has allowed us to prepare multi-tiered systems that display the influence of pi-stacking. The stacked architectures were prepared by multi-step synthesis of the scaffolds, followed by metal-catalyzed cross coupling reactions (Sonogashira, Heck, Suzuki couplings) to incorporate the conjugated oligomers. The optical and electrochemical properties of these stacked compounds and polymers were compared to their unstacked linear counterparts. These studies provide a platform for the exploration of the nature of charge carriers and excitons in a broad class of materials that have significant potential in addressing challenges in power generation, lighting and electronics.

Streszczenie:
Ces travaux de thèse portent sur la synthèse de polymères π-conjugués biosourcés issus de la vanilline, visant des applications potentielles en électronique organique (photovoltaïque ou Organic Light Emitting Diode, OLED). Des polyazométhines de masses molaires élevées, issus de la copolymérisation entre la divanilline et différentes diamines, ont été obtenus par polymérisation sous irradiation micro-onde durant 5 minutes puis séchage à l’évaporateur rotatif. Ces derniers ont une absorbance dans le proche UV mais un chemin de conjugaison très court, comme l’a révélé l’analyse de molécules modèles. Pour améliorer ce chemin de conjugaison, une molécule à base de divanilline a été synthétisée avec les fonctions aldéhyde en position para par rapport à la liaison entre les deux cycles aromatiques. Cette para-divanilline, encore jamais décrite, a été utilisée pour la synthèse de polyazomethines. Ces derniers présentent également un court chemin de conjugaison en raison de l’encombrement stérique entre les deux groupes phényle. Une dernière famille de polymère a alors été étudiée : les polythiazolothiazoles à base de divanilline. Ces polymères présentent des propriétés d’émission qui se caractérisent par une émission dans le bleu en solution et dans le jaune à l’état de film. Des molécules modèles à base de benzothiazole ont également été synthétisées et présentent un rendement quantique de fluorescence de 20% ainsi qu’un empilement π en « chevrons », leur conférant un fort potentiel pour diverses applications en électronique organique
The objective of this PhD is to synthesize π-conjugated bio-based polymers from vanillin, with potential applications in the field of organic electronic (photovoltaic, Organic Light Emitting Diode, OLED). Polyazomethines with high molar masses were obtained via the copolymerization of divanillin with various diamines. This polycondensation was performed in 5 minutes under microwave irradiation, followed by solvent removal using a rotary evaporator. Divanillin-based polyazomethines absorb in the near-UV range but have a short conjugation pathway, as revealed investigations on model compounds. To improve this conjugated pathway, a divanillin-based molecule bearing aldehyde functions in para positions with respect to the link between the rings, was designed. This so-called para-divanillin, never reported before, was copolymerized to yield polyazomethines. These latter polymers also have a short conjugation pathway due to steric hindrance between the two aromatic rings of the para-divanillin skeleton. A last family of divanillin-based polymers was thus investigated: polythiazolothiazoles. The latter exhibit specific emission properties as they emit in the blue range in solution and in the yellow range in films. Benzothiazole-based model compounds were also synthesized and exhibited a fluorescence quantum yield of 20% and “herringbone-like” π-stacking, giving them a strong potential for various organic electronic applications

In recent years, the promising prospects for applications of polymers in optoelectronic and nonlinear optical devices have stimulated much interest in their fundamental optical properties. Among the attractive polymers for electroluminescent devices are poly(phenylenevinylene)(PPV) and poly(phenyl-p-phenylenevinylene) (PPPV). Although high quantum yields are demonstrated [1], several fundamental properties like the large Stokes shift between absorption and luminescence are not well understood. For an optimization of material parameters, a detailed understanding of the optical response is needed.

Streszczenie:
Optically pumped gain narrowing and lasing have been demonstrated in submicron thick films, neat and undiluted, of photoluminescent conjugated polymers. The dramatic collapse of the emission line width occurs at very low pump energy thresholds (~10 μJ/cm2). Gain narrowing is found in over a dozen different conjugated polymers representing a variety of molecular structures, including poly(p-phenylenevinylene), poly(p-phenylene) and polyfluorene derivatives; the emission wavelengths in these materials span the visible spectrum. The short gain lengths in conjugated polymers are attributed to the high density of chromophores, the large density of states associated with the interband (π-π*) transition in quasi-one-dimensional systems, and the Stokes shift which minimizes self-absorption and allows optical pumping to the excited state without simultaneously stimulating emission (thereby yielding population inversion). Lasing and gain narrowing are compared for a soluble poly(phenylene vinylene) derivative using two different resonant structures: planar waveguides and microcavities. In both cases, the gain narrowing threshold is at 0.05 - 0.1 μJ per 10 ns pulse focused to approximately 1.5 mm. Single mode microcavity lasers are obtained when a cavity resonance occurs at the wavelength where the gain of the polymer is a maximum. Low threshold lasing (threshold more than an order of magnitude below that observed in planar waveguides and microcavities) has also been demonstrated using distributed feedback in a planar chip film configuration.

Poly(p-phenylenevinylene) (PPV) is a typical representative of conjugated polymers, which have a highly delocalized, one-dimensional conjugated π-electron system. These polymers have found much interest, because most of them can be processed rather easily to thin film waveguides and because of their large third-order nonlinearities [1-3]. Thin films of PPV are prepared by spin-coating of a soluble precursor polymer on fused silica substrates and thermal annealing under vacuum as described recently [4]. We have used thin films of PPV to develop and demonstrate a sensitive characterization method of the intensity dependent refractive index n = n0 + n2I and absorption coefficient α = α0 + α2I. The utility of any material for applications in photonics depends primarily on these quantities.
