<dcterms:abstract xml:lang="fr">Les composés photo- et électroluminescents sont omniprésents dans la société contemporaine, et la recherche de nouveaux émetteurs implique pratiquement toutes les catégories de molécules, des molécules organiques conjugués aux composés de coordination et organométalliques. Dans le cadre de ce travail, l’accent sera mis sur deux motifs hétéroaromatiques privilégiés et polyvalents, le benzo[d]thiazole et le thiazolo[4,5-d]thiazole, qui peuvent agir à la fois comme émetteurs organiques et comme ligands, conduisant à des complexes métalliques luminescents. Le chapitre 1 présentera les concepts nécessaires à la compréhension de l’état de l’art et des objectifs de cette étude. Le chapitre 2 introduira trois familles inédites d’émetteurs π-étendus, accompagnées d’une investigation chimique et photophysique approfondie, ainsi que de leur intégration dans des dispositifs OLED. Enfin, le chapitre 3 exploitera certains de ces émetteurs comme ligands pour des métaux de transition d10, en particulier Cu(I) et Ag(I), afin d’étendre l’émission de ces complexes dans le proche infrarouge (NIR). De nombreuses familles de complexes mono- et binucléaires seront ainsi présentées, avec une étude photophysique complète en solution et à l’état solide.</dcterms:abstract>
<dcterms:abstract xml:lang="en">Photo- and electroluminescent compounds are ubiquitous in modern society, and the search for innovative emitters involves virtually all kinds of molecules, from conjugated organic scaffolds to coordination and organometallic compounds. In this work, we will mainly focus on two privileged and versatile heteroaromatic scaffolds, namely benzo[d]thiazole and thiazolo[4-5d]thiazole, which may act as organic emitters and as ligands, yielding emissive transition metal complexes. Chapter 1 will deal with concepts needed to understand the state of the art and scope of this work. Chapter 2 will present three families of novel π-extended emitters accompanied by their comprehensive chemical and photophysical investigation and their implementation in experimental OLED devices. Some of these emitters will be then employed in chapter 3 as ligands for d10 transition metals, namely Cu(I) and Ag(I), with the aim of pushing the emission of these complexes in the NIR. Numerous families of mono- and binuclear complexes will thus be presented, along with their full photophysical investigation in solution, solid state, and as polymer-doped thin films.</dcterms:abstract>
