📄 Abstract: c (OE), which aims to design innovative and high-performance devices, exploits the properties of organic semiconductors (OSCs) through detailed structure-property studies. In this thesis, two families of OSCs were investigated in distinct but complementary contexts: nanohoops and pure hydrocarbons (PHCs).
The first part focuses on donor-acceptor nanohoops, strained and original π- conjugated structures, for which a solid structure-property relationship has been established. The study of nanohoops with varying sizes and arrangements, synthesized via a modular approach, highlighted the influence of these parameters on their properties, paving the way for potential applications in OE
The second part is built on this type of well-established structure-property relationship to develop new PHC-based host matrices, composed exclusively of carbon and hydrogen atoms, aimed to improve the stability and performance of blue organic light-emitting diodes (OLEDs). Host matrices derived from spirobifluorene (SBF), a notable fragment among PHCs for the precise control it offers over material properties, were designed and led to blue OLED devices that are both stable and highly efficient.
The two part of this manuscript are representative of research in organic electronics: the first, fundamental, aiming to establish a structure-property relationship, and the second, applied, dedicated to pushing the performance of current devices.

📄 Résumé : L’utilisation de composés issus de la biomasse représente une voie prometteuse et respectueuse de l’environnement pour le développement de matériaux durables pour les cellules solaires organiques. Les molécules biosourcées, tels que le glucose, le furfural ou le gaïacol, offrent une grande diversité structurale et fonctionnelle, permettant la conception de nouveaux matériaux conjugués aux propriétés optoélectroniques ajustables. Cette thèse vise à développer de nouveaux matériaux semiconducteurs en maximisant l’utilisation de ressources biosourcées. Une étude méthodologique sur la formation de liaisons Csp2-Csp2 par couplage décarboxylant a été menée. Il a ainsi été mis au point une séquence oxydation-couplage décarboxylant pour une synthèse efficace de systèmes π-conjugués. Enfin, des composés donneurs d’électrons à base de glucose ont été synthétisés. Les premières cellules solaires intégrant des glucoses monofonctionnalisés ont été évaluées. La préparation des glucoses comportant deux systèmes conjugués distincts, ainsi que l’étude de leurs propriétés opto-électroniques, ont également été rapportées. Cette étude met en évidence les avantages liés à l’utilisation de composés biosourcés et la faisabilité de l’incorporation du glucose dans les matériaux actifs.

📄 Abstract : The use of biomass-derived compounds offers a promising and environmentally friendly pathway for the development of sustainable materials for organic solar cells. Biosourced molecules such as glucose, furfural, and guaiacol provide significant structural and functional diversity, enabling the design of new materials with tunable optoelectronic properties. This thesis aims to develop new semiconductor materials by maximizing the incorporation of biosourced resources. A methodological study on Csp2–Csp2 bond formation via decarboxylative cross-coupling was conducted. An oxidation–decarboxylative coupling sequence was thus developed to enable the efficient synthesis of π-conjugated systems. Finally, electron-donor compounds grafted onto glucose were also synthesized. First solar cells using monofunctionalized N-glucosides were evaluated. The preparation of glucose based molecules bearing two distinct conjugated systems, along with the study of their optoelectronic properties, were reported. This study highlights the advantages of using bio-based compounds and demonstrates the feasibility of incorporating glucose into active materials.

📄 Abstract: This thesis focuses on the development of new electrochemical sensors for the detection of two analytes: erythromycin (ERY) and diclofenac (DCF). In the first approach, detection relied on the integration of recognition elements based on single-stranded DNA molecules, known as aptamers. An aptamer specific to ERY was immobilized via self-assembled monolayer (SAM) formation on a gold substrate. The surface functionalization protocol was thoroughly optimized to ensure stable baseline signals and avoid false positives. In a more unconventional approach, a DCF-specific aptamer was immobilized on a carbon electrode through click chemistry. The electrode surface was pre-functionalized by electrochemical reduction of the protected diazonium salts. The same strategy was then adapted to a graphene field-effect transistor (GFET), yielding an electronic sensor with improved analytical performance. Finally, a photolithographed ultramicroelectrode array was developed and coupled with the sampled-current voltammetry (SCV) technique. The array was characterized by both optical and electrochemical methods. Coupling with SCV led to lower limits of detection and higher sensitivity compared to its macroelectrode counterpart. Moreover, this approach enabled efficient direct detection of DCF, mitigating the electrode passivation typically associated with its electrochemical oxidation.

As part of Yuliia Oleksii’s PhD defense scheduled for Friday December 5th 2025, Professor Mohamed Eddaoudi from King Abdullah University of Science and Technology (Saudi Arabia) will deliver a seminar on Metal-Organic Frameworks (MOFs).
📅 Date: Thursday, December 4, 2025 – 2:30 PM
📍 Location: Amphitheater L003, Faculty of Science, University of Angers

📄[ABSTRACT] Demand for functional materials targeted for specific applications is ever increasing as societal needs and demands mount with advancing technology. Evidently, improvement of existing materials and quest for new approaches to the design of novel materials are both valuable paths worth pursuing in order to address the myriad technological challenges that face us, pertaining to energy and environmental sustainability.
Metal-organic frameworks (MOFs) are a unique class of solid-state materials amenable to design and manipulation for desired function and application, thanks to advancement in reticular chemistry and the various design strategies developed for its effective practice.1 Several design strategies have been conceived and developed to target viable MOF platforms, from the single-metal-ion molecular building block (MBB) approach to the hierarchical supermolecular building block and supermolecular building layer approaches (SBB and SBL, respectively) to the merged nets approach,2 and centering structure-directing agents (c-SDA) strategy.3 This inherent built-in information allows access to highly stabile and made-to-order porous materials, with controlled pore-aperture size and/or inner pore system functionality, toward applications pertaining to energy and environmental sustainability. Specifically, MOF materials addressing the energy-intensive separations and carbon capture will be highlighted, as well as insights into MOF based membranes, namely pure MOF membranes and mixed matrix membranes (MMMs), construction and their respective gas separation properties.4
📄[BIOGRAPHY] Professor Mohamed Eddaoudi is an Ibn Alhaythamen Distinguished Professor of Chemical Sciences and Chair of the Advanced Membranes and Porous Materials (AMPM) Center at King Abdullah University of Science and Technology (KAUST), Saudi Arabia.
Professor Mohamed Eddaoudi is a pioneer in the chemistry of metal-organic frameworks (MOFs), designing and introducing new strategies for reticular chemistry, rational design, and construction of functional solid-state materials. His work focuses on the design and synthesis of functional porous solids for energy and environmental sustainability: hydrogen storage, methane storage, CO₂ capture, and direct air capture (DAC). He also designs and synthesizes functional adsorbents and membranes, enabling energy-efficient and cost-effective gas separations.
