Thomas-Claudepierre, Anne-Sophie. "The cohesin and mediator complexes control immunoglobulin class switch recombination". Thesis, Strasbourg, 2014. http://www.theses.fr/2014STRAJ112/document.
Texto completoDuring immune responses, B cells diversify their repertoire through somatic hypermutation (SHM) and class switch recombination (CSR). Both of these mechanisms are dependent on the activity of activation-induced cytidine deaminase (AID), an enzyme that deaminates cytosines into uracils generating mismatches that are differentially processed to result in SHM and CSR. During CSR, the Ig heavy chain (IgH) locus undergoes dynamic three-dimensional structural changes in which promoters, enhancers and switch regions are brought into close proximity. Nevertheless, little is known about the underlying mechanisms. To gain insight into the molecular mechanism responsible for AID regulation during CSR, we performed a proteomic screen for AID partners and identified CTCF, cohesin and mediator complexes, which are factors previously implicated in long-range interactions. We showed that during CSR, the mediator complex is required for acceptor switch region transcription, long-range interaction between the enhancer and the acceptor switch region and AID recruitment to the IgH locus whereas the cohesin complex is required for proper AID-induced breaks repair and might favor switch regions synapsis
Dalloul, Iman. "Switch Canonique en Cis ou Trans et Recombinaisons Suicides du Locus IgH". Thesis, Limoges, 2018. http://www.theses.fr/2018LIMO0049.
Texto completoB-cell activation is accompanied by remodeling of immunoglobulin genes resulting in affinity maturation of Ig variable regions by somatic hypermutation (SHM) and class switch recombination (CSR). These two processes are under the control of the 3' regulatory region (3’RR) of the IgH locus. During CSR, the IgH locus undergoes three dimensional changes bringing the AID-targeted switch regions near the 3'RR region to facilitate recombination. The MED1 subunit of the Mediator complex promotes this long-distance interaction with the 3'RR, but it is also implicated in germinal transcription preceding CSR in order to facilitate AID activity. As recently demonstrated in mice, the 3'RR region can also be targeted by AID-mediated recombination, but unlike CSR, this type of recombination joining the Sμ region and 3'RR (called Locus Suicide Recombination or LSR) results in a complete deletion of all the constant genes leading to B-cell death by loss of B Cell Receptor expression. We now show that AID-mediated LSR also occurs in activated human B cells with the two 3'RR (3'RR1downstream of Cα1 and 3'RR2 downstream of Cα2) and affects the functional allele. It can also be bi-allelic marked by the absence of this type of recombination in plasma cells of the bone marrow but also in quiescent blood memory B cells. LSR occurs at high level when the memory B cells are reactivated. All in-vitro stimulations induce LSR, without identifying conditions favoring either CSR and the LSR. Our results also show that the MED1 subunit appears to influence 3’ RR transcription and LSR in mice. Conditional inactivation of MED1 influences transcriptional accessibility and therefore recombination without affecting epigenetic markers of the IgH locus. This study also revealed that all the processes controlled by the 3'RR are "mediator -dependent" (SHM, CSR without distinction between Cis and Trans -CSR, increased expression of the IgH locus in the plasma cells ...), as well as the choice of varia ble segments during VDJH rearrangements
Schiavo, Ebe. "Molecular mechanisms controlling immunoglobulin class switch recombination". Thesis, Strasbourg, 2013. http://www.theses.fr/2013STRAJ084/document.
Texto completoDuring immune responses, B cell repertoire is diversified through somatic hypermutation (SHM) and class switch recombination (CSR). SHM and CSR require activation-induced cytidine deaminase (AID), which induces DNA damage. While AID deficiency abrogates SHM and CSR, C-terminal truncations impair CSR without affecting SHM and it has been proposed that AID C-terminal domain associates with CSR-specific factor(s). In order to identify these factors, we studied a human CSR-specific immunodeficiency, characterized by normal SHM and AID expression. B cells from these patients do not display DSBs at switch (S) regions, suggesting that they might lack an AID-binding factor(s) required to target AID to S regions during CSR. Through a multi- approach strategy, we identified and analyzed candidate factors, including Spt6, the cohesin complex and the Smc5/6 complex. We show that, in B cells poised to undergo CSR, AID is in a complex with Spt6, Spt5, the RNA polymerase II and the PAF complex while cohesins might regulate the 3D structure of the IgH locus and the pathway of DSBs repair at the Ig S regions. Our work thus contributes to a better understanding of the CSR reaction
Simonetti, Fabrizio. "Study of the mechanisms of sexual differentiation in the fission yeast S. pombe". Thesis, Université Paris-Saclay (ComUE), 2017. http://www.theses.fr/2017SACLS081/document.
Texto completoIn the fission yeast S. pombe, several meiotic mRNAs are constitutively expressed during the mitotic cell cycle. In order to avoid untimely entry into meiosis, cells have adopted a degradation system that selectively eliminates the corresponding mRNAs. The YTH family RNA-binding protein Mmi1 recognizes specific sequence motifs within these transcripts (UNAAAC) and allows their targeting to the nuclear exosome for degradation. Upon entry into meiosis, Mmi1 is sequestered in a ribonucleoprotein complex, composed by the meiotic protein Mei2 and the non-coding RNA meiRNA, allowing meiotic mRNAs to be exported and translated. During my PhD studies, I focused my interest on the role of Mmi1 in the degradation of meiotic transcripts during vegetative growth. In accord with recent studies, our results show that Mmi1 stably interacts with the mRNA deadenylation complex Ccr4-Not. This interaction has a functional relevance since Ccr4-Not is involved in the degradation of meiotic mRNAs. Surprisingly, however, the deadenylation activity is not required. Our genetic and biochemical analyses indicate that the E3 ubiquitin ligase Mot2, subunit of the Ccr4-Not complex, ubiquitinate a pool of the inhibitor of Mmi1, the Mei2 protein, to favor its degradation by the proteasome. This regulatory mechanism ensures the maintenance of Mmi1 in a functional state, leading to the persistent repression of meiotic mRNAs in mitotic cells. Thus, Mmi1 has a dual role: in nuclear mRNA surveillance, by targeting meiotic transcripts for degradation by the exosome, and in protein degradation, by recruiting Ccr4-Not to its own inhibitor Mei2. These results have also revealed a novel role for the ubiquitin ligase activity of the Ccr4-Not subunit Mot2 in the control of sexual differentiation in fission yeast. Our supplemental results indicate that the YTH RNA-binding domain of Mmi1, but not the non-coding RNA meiRNA, is required for the degradation of Mei2. Remarkably, our results also revealed that the YTH domain of Mmi1 has a key role in the interaction with Mei2. This strongly suggests that the YTH domain acts as a bifunctional module, allowing the binding not only to meiotic RNAs but also to proteins, such as Mei2. We discuss these results within the context of the current literature and we propose a novel model for the control of sexual differentiation by the Mmi1-Mei2 system

Texto completoNowadays the cancer community agrees on the need for patient-tailored diagnostics and therapies, which calls for the design of translational studies combining experimental and statistical approaches. Current challenges include the validation of preclinical experimental models and their multi-omics profiling, along with the design of dedicated bioinformatics and mathematical pipelines (i.e. dimension reduction, multi-omics integration, mechanism-based digital twins) for identifying patient-specific optimal drug combinations.To address these challenges, we designed bioinformatics and statistical approaches to analyze various large-scale data types and integrate them to identify targetable vulnerabilities in cancer cell lines. We developed our pipeline in the context of alterations of the SWItch Sucrose Non-Fermentable (SWI/SNF) chromatin remodeling complex. SWI/SNF mutations occur in ~20% of all cancers, but such malignancies still lack efficient therapies. We leveraged a panel of HAP1 isogenic cell lines mutated for SWI/SNF subunits or other epigenetic enzymes for which transcriptomics, proteomics and drug screening data were available.We worked on four methodological axes, the first one being the design of an optimized pathway enrichment pipeline to detect pathways differentially activated in the mutants against the wild-type. We developed a pruning algorithm to reduce gene and pathway redundancy in the Reactome database and improve the interpretability of the results. We evidenced the bad performance of first-generation enrichment methods and proposed to combine the topology-based method ROntoTools with pre-ranked GSEA to increase enrichment performance .Secondly, we analyzed drug screens, processed drug-gene interaction databases to obtain genes and pathways targeted by effective drugs and integrated them with proteomics enrichment results to infer targetable vulnerabilities selectively harming mutant cell lines. The validation of potential targets was achieved using a novel method detecting synthetic lethality from transcriptomics and CRISPR data of independent cancer cell lines in DepMap, run for each studied epigenetic enzyme. Finally, to further inform multi-agent therapy optimization, we designed a first digital representation of targetable pathways for SMARCA4-mutated tumors by building a directed protein-protein interaction network connecting targets inferred from multi-omics HAP1 and DepMap CRISPR analyses. We used the OmniPath database to retrieve direct protein interactions and added the connecting neighboring genes with the Neko algorithm.These methodological developments were applied to the HAP1 panel datasets. Using our optimized enrichment pipeline, we identified Metabolism of proteins as the most frequently dysregulated pathway category in SWI/SNF-KO lines. Next, the drug screening analysis revealed cytotoxic and epigenetic drugs selectively targeting SWI/SNF mutants, including CBP/EP300 or mitochondrial respiration inhibitors, also identified as synthetic lethal by our Depmap CRISPR analysis. Importantly, we validated these findings in two independent isogenic cancer-relevant experimental models. The Depmap CRISPR analysis was also used in a separate project to identify synthetic lethal interactions in glioblastoma, which proved relevant for patient-derived cell lines and are being validated in dedicated drug screens.To sum up, we developed computational methods to integrate multi-omics expression data with drug screening and CRISPR assays and identified new vulnerabilities in SWI/SNF mutants which were experimentally revalidated. This study was limited to the identification of effective single agents. As a future direction, we propose to design mathematical models representing targetable protein networks using differential equations and their use in numerical optimization and machine learning procedures as a key tool to investigate concomitant druggable targets and personalize drug combinations

Texto completoActivation-induced cytidine deaminase (AID) initiates immunoglobulin (Ig) diversification by inducing DNA damage. While on-target lesions are crucial for mounting highly specific and adaptive immune responses, off-target lesions contribute to malignant cell transformation. Despite its implications, the events following AID recruitment that enforce genome integrity in B cells remain poorly defined. It is not understood why multiple non-Ig loci bound by AID are not mutated or why AID-induced DNA lesions may lead to mutations or DNA breaks. To address this question, we developed a single-locus proteomic approach coupling proximity-dependent protein identification and genome editing (CRISPR/Cas9) to identify and compare the proteins recruited at individual genomic loci bound by AID. We performed the proof of principle of this innovative tool by identifying the proteome of abundant genomic loci. On the other hand, we functionally characterized Parp3, Parp9 and Med1, identified as AID partners, revealing novel mechanisms that tightly control AID activity and DNA repair during Ig diversification

Texto completoThis work is devoted to the synthesis and characterization of novel molecular switches and wires that incorporate ruthenium organometallic moieties. First, a bibliographic chapter presents the advantages and applications of the building blocks used in the following chapters and discuss the general context of molecular electronics. The second part of this manuscript deals with preparation, electrochemical and photophysical studies of bimetallic ruthenium complexes bearing a triarylamine core. The goal is to modulate the luminescence of this core by changing the states of the redox-active ruthenium acetylide moieties. In the third part, combinations of Ln (Ln = Eu or Yb) complexes and redox-active ruthenium vinyl bipyridine moieties were formed in order to tune the luminescence of Ln center via oxidation of the redox-active ruthenium vinyl moieties. The fourth part describes an association of a Ln (Ln = Eu or Yb) precursor and a ligand bearing a dithienylethene (DTE) unit, in order to commute the light emission of the Ln center. These DTE-Ln compounds were successfully synthesized and their luminescence was reversiblely modulated by photo irradiation. In the last part, we report the synthesis of a series of redox-active molecular wires, which are ruthenium (II) bis(σ-arylacetylide) complexes terminated with amine functional groups, one of them including a photochromic DTE unit. These molecules are designed to covalently bridge a gap between graphene electrodes for probing the electrochemical gating of conductance via oxidation of the molecules. Furthermore, the photochromic complex should allow combined optical and electrochemical conductance switching in single molecule graphene junctions

Texto completoA new family of chiral bridled porphyrins was designed in order to access systems presenting an irreversible redox process linked to a conformational switch. Such systems could be of high interest in the field of molecular memories. These new porphyrins are made of two bridles anchored to the four macrocycle meso positions through cyclohexyl groups. The first objective is to introduce a secondary amine in the centre of the bridles in order to allow metalloporphyrins with defined bridle length and specific metal with a given oxidation degree to be only under one conformation at equilibrium. The second objective is to favor a conformational switch dependent on the oxidation state of a redox metal such as manganese. To reach these goals, a new porphyrin synthetic pathway was established. The key steps of this new protocol were the synthesis of the bridle built around the central amine with two terminal aldehyde functions required for the macrocyle formation. Porphyrins were studied by NMR, UV-Visible and circular dichroism spectroscopies. The conformations of free base porphyrins, zinc(II) complexes and nickel(II) complexes were determined by 1H NMR. For a bridle with a chain length of 9 atoms including the secondary amine, the zinc(II) complex presents only an αααα conformation and nickel(II) complex an ααββ conformation. From these structural models, manganese(II) and chloromanganese(III) complexes were synthesised and characterised by UV-Visible spectroscopy, circular dichroism and 13C NMR in order to study the possible conformational switches dependent on the Mn redox state

In the second part explained the combination of photochromic DTE units with ruthenium acetylide moieties to attach on the surface of metal nanoparticles in order to tune their plasmonic resonance through the surface environment modification by using light and redox stimuli. The third part describes the preparation of lanthanide complexes combined with a spiropyran photochromic unit in order to switch the SMM properties of the complexes via photoisomerization of the spiropyran unit. In the last part, we report the synthesis of Oligo(phenylene ethylene) molecular wires with different central cores in order to obtain various wire with different HOMO-LUMO energy levels to check the effect of pinning

Texto completoIn this PhD work, we firstly developed two studies based on the so-called ''stiff stilbene'' units that are known to reversibly interconvert between two trans and cis forms through light. The first study corresponds to photoresponsive chiral switches based on helicenes, the other one to photoresponsive gold(I) complexes. Then, we dealt with the synthesis and characterization of helicene-bipyridine based Dy(III) complexes as novel kinds of chiral single molecule magnets (SMMs) and compared the difference of the magnetic properties between racemic and enantiopure SMMs. Finally, we developed the first use of the reversible sterodivergent cycloaddition of racemic helicenes onto [60]fullerene with its subsequent retro-cycloaddition as an efficient alternative strategy for the enantiomeric resolution of a helicene-carboxaldehyde

Texto completoThe work of this thesis is devoted to the development of original photo-switchable ruthenium(II) complexes incorporating the photochromic Dimethyldihydropyrene (DHP) / Cyclophanediene (CPD), for future optoelectronic molecular devices.In order to realize complex systems capable of reproducing the functions of a logic circuit, an interesting strategy is based on the association of photo-switchable molecules and metal complexes. However, this strategy is confronted with some major obstacles, generally associated with the loss of the switching properties of organic photochromes. In response to previous results confirming this trend, two new families of DHP-based terpyridine ruthenium(II) complexes have been synthesized. Since the presence of pyridinium function significantly improves the isomerization properties of the DHP core, the metal centers were connected either via a pyridinium benzyl linkage (Ru-Lpy+tpy) or via an aryl pyridinium linkage (Ru-LZincke). Although operating at lower energy, Ru-LZincke complex exhibits lessened performance, whereas Ru-Lpy+tpy complexes exhibit a notable preservation of their switching properties. Following the discovery of an original photo-reactivity favored by the presence of metal center, an analogue family based on ruthenium (II) bipyridine complexes (Ru-Lpy+bpy) was studied. Even if the mechanisms are not completely rationalized, Ru-Lpy+bpy complexes have proved to be remarkable candidates for the realization of quantitatively reversible photo-switches in the visible domain

Texto completoThis thesis is devoted to the design and characterization of switchable molecular systems (molecules, materials and electronic devices) incorporating the dimethyldihydropyrene / cyclophanediene (DHP/CPD) photochromic couple. The first part deals with the synthesis and characterization of original photochromic molecules based on the dimethyldihydropyrene unit. In particular, the chemical functionalisation of these molecular systems with electron-withdrawal pyridinium groups leads to an improvement of the kinetics of photo-induced conversion while providing an easily functionalizable unit, for example with metal cations complexing units. In the second part, the photochromic core is covalently linked with metal complexes based on terpyridine derivatives, conferring redox-active properties to the molecular architecture. These assemblies are applied for the design of organized thin films obtained by self-assembly of metallopolymers on solid surfaces. The model complexes and films display photochromic properties and redox activity particularly promising for the design of responsive materials and molecular devices. Finally, we present the study of the conductance of the isomers DHP and CPD. A single molecule electronic device in which individual molecules are utilized as active electronic components has been implemented using the photochromic group functionalized with two pyridine units, used as anchoring functions. It appears that the DHP isomer has a conductance of about four orders of magnitude higher than the corresponding isomer CPD. These two states can be switched very reproducibly and reversibly upon application of optical and thermal stimulus

They do exclusively exist as their enaminone tautomeric form both in solid-state and in solution phase. In their corresponding Schiff base complexes of NiII and CuII, the central metal is tetracoordinated in a square-planar environment. The coordination sphere is formed by the nitrogen and oxygen atoms of the dianionic tridentate ligand and the fourth coordination site is occupied by the nitrogen atom of the pyridine co-ligand. The derivative exhibited a high quadratic hyperpolarizability (β1.91) determined by the HLS technique. Substitution of 4,4’-bipyridine for pyridine invariably leads to the formation of the respective dimers [(R-ONO)MII(4,4’-bipy)MII(ONO-R)]. A similar compound having the bis(4-pyridyle)acetylene as spacer was formed upon cross-coupling Sonogashira reaction with ethynylpyridine chlorhydrate. The same cross-coupling reaction carried out between the electron releasing and electron withdrawing building blocks, respectively, allowed the preparation of the expected «push-pull» D-π-A system. The second-order NLO responses of compounds bearing a redox active methylenepyran ligand can be modulated upon reversible bi- (R = An) and tetra- (R = Fc) oxydation involving C-C bond formation/breaking reactions, thus forming a new class of NLO molecular switches

Texto completoOne of the main research directions of modern chemistry is the synthesis and study of new switchablecompounds which can change their properties under external stimuli (temperature, light, magnetic orelectric field…). These systems can store the information at the molecular level. In this contextamongst the most studied systems in coordination chemistry are the 3D networks and the molecularPrussian blue analogs. This thesis deals with the synthesis and characterizations of new{Fe(µ-CN)M} (M = Fe, Mn, Co) molecular Prussian blue analogs. In the first chapter electrontransfer compounds are described in order of decreasing of their dimensionality, from 3D to thediscrete 0D systems. The second chapter describes the synthesis and structural, spectroscopic,electrochemical and magnetic characterizations of [MII(LN5)]2+ precursors (MII = Fe, Mn, Co) and[FeIII(LN3/LN2)(CN)n]- (n = 2, 3) (LN5, LN3, LN2 - nitrogen-based penta-, tri- and bi-dentate ligands,respectively), which are used in the synthesis of the binuclear complexes. Chapter three presents thesynthesis and structural, magnetic, spectroscopic and electrochemical studies of four binuclearparamagnetic {FeIII(µ-CN)MII} complexes (MII = Fe, Co). Chapter four is focused on the synthesisand spectroscopic, magnetic, photomagnetic and electrochemical properties of three binucleardiamagnetic {FeII(µ-CN)CoIII} electron transfer complexes

Texto completoThis thesis is dedicated to the synthesis of new dinuclear cyanido-bridged Co/Fe complexes, which mimics on a single molecule the original properties of the coordination network of Prussian Blue Analogues AxCo[Fe(CN)6]y•nH2O (A= alkaline ions), i.e. intramolecular thermal and photo-induced electron transfer in the solid state. We focus on the study of the physical properties of the simplest Fe/Co PBA, a dinuclear complex, with the hope to understand the fundamental concepts of this fascinating phenomenon. Chapter I contains the most representative examples of Fe/Co PBAs, focusing on the synthetic strategies employed in order to obtain Fe/Co PBAs of different dimensionalities and the techniques used to understand their photomagnetic properties. The theoretical background of the electron transfer phenomenon and the motivation of our work are described in the end of the chapter. After introducing the choice of the building blocks used in this work through the study of their redox potential properties, chapter II is devoted to the synthesis and the characterization of a novel dinuclear Fe/Co cyanido-bridged complex, which exhibits metal-to-metal electron transfer properties in solid state triggered by temperature and light. The ET phenomenon has been also studied by X-ray absorption spectroscopy and dielectric measurements. In Chapter III is illustrated the influence of the environment content of the dinuclear Fe/Co complexes, such as the counter ions, on the occurrence of the thermally and/or photo-induced electron transfer in solid state, thus highlighting the versatility of these molecular materials. Finally in chapter IV, the possibility of transferring the electron transfer phenomenon of the studied Fe/Co pairs from solid state to solution is investigated

Texto completoThe first part of this thesis work concerns the development of an ultra–high–vacuum experimental system, hosting a commercial Low Temperature Scanning Tunneling Microscope (LT-STM), that has been built for characterizing and manipulating single molecules and molecular complexes adsorbed on metal surfaces. The design from scratch, the commissioning and the performance tests of the various components of the system are presented. The preparation chamber that has been developed provides the fundamental surface preparation and analysis instruments, combining the STM analysis with other experimental techniques and allowing for easy setup of additional preparation/analysis instruments. The manipulator sample stage allows for a wide temperature range, needed for the preparation of a variety of surfaces to be investigated in the LT-STM. In the second part of this work, we present two examples of how molecules and molecular complexes can be studied and manipulated with the LT-STM technique. In the first example, within a collaboration established with the group of Dr. Leonhard Grill at the Freie Universität in Berlin, we have characterized an azobenzene derivative adsorbed on the Au(111) surface, a known molecular switch based on a trans–cis isomerization, which can be reversibly induced by the tip of the STM with controlled voltage pulses. We could show how the molecule–molecule interactions play a critical role in determining the switching abilities of the molecules between different self–assembled molecular islands, and how the molecule–substrate interaction can efficiently determine two different spatial periodicities of the switching molecules. In the second example, we have presented preliminary results regarding the characterization of the NH3-NO complex which forms on the Pt(111) surface, showing that by exploiting the manipulation and spectroscopic tools of the LT-STM, it will be possible to investigate at the atomic scale the properties of the hydrogen bond most likely involved the complex.
La prima parte di questa tesi descrive lo sviluppo di un sistema sperimentale da ultra–alto–vuoto, dotato di un microscopio a scansione a effetto tunnel a bassa temperatura (LT-STM) disponibile in commercio. Il sistema è stato concepito e costruito per caratterizzare e manipolare singole molecole e complessi di molecole adsorbiti su superfici metalliche. Viene descritta la realizzazione del sistema sperimentale, a partire dalla fase di progettazione fino alla messa in opera e ai vari test di funzionamento che sono stati effettuati. La camera di preparazione che è stata costruita è provvista della strumentazione di base per la preparazione e l’analisi dei campioni di misura, e permette di integrare la tecnica STM con altre tecniche sperimentali e di installare in modo semplice e veloce nuovi strumenti. Il manipolatore è dotato di un sistema di riscaldamento campioni che permette di raggiungere un largo intervallo di temperature, necessario per la preparazione di svariati tipi di campioni da poter studiare tramite l’LT-STM. Nella seconda parte della tesi, vengono presentati due esempi di come, grazie alle potenzialità dell’LT-STM, è possibile caratterizzare e manipolare molecole e complessi di molecole. Nel primo dei due esempi, nell’ambito di una collaborazione con il gruppo del Dr. Leonhard Grill presso la Freie Universität a Berlino, è stato studiato sulla superficie (111) dell’oro il comportamento di un derivato dell’azobenzene, un “interruttore molecolare” basato sul processo di isomerizzazione trans–cis che può essere indotto in modo reversibile tramite impulsi di voltaggio dalla punta del microscopio STM. Si è dimostrato come le interazioni inter–molecolari giocano un ruolo fondamentale nel determinare se, all’interno di isole molecolari con diversa struttura, le molecole possono isomerizzare o meno; inoltre è stato scoperto che l’interazione delle molecole con il substrato può determinare l’ordinamento delle molecole in grado di isomerizzare, in strutture di periodicità definita all’interno delle isole molecolari. Nel secondo esempio che viene descritto, vengono presentati i risultati preliminari della caratterizzazione del complesso NH3-NO che si forma sulla superficie (111) del platino, e viene indicato come sarà possibile caratterizzare la natura dei legami idrogeno, che probabilmente stabilizzano il complesso, tramite le tecniche spettroscopiche e di manipolazione messe a disposizione dall’LT-STM.

Texto completoOver the past decade many efforts have been focused on the synthesis, modification and application of multi-responsive molecular systems. Up to now, two main strategies have been conducted to elaborate such systems: either by connecting different molecular switches through covalent links or by mixing them within supramolecular assemblies to obtain multiresponsiveness through the combination of various stimulations (i.e., photon, electron, proton, etc…). In thisthesis, we report a different approach based on the employment of identical indolinooxazolidine (BOX) unit as multi-modal switch. Indeed, the opening of the oxazolidine ring can be reversibly and selectively achieved either under UV irradiation, electrochemical stimulation or acidity changes. According to our first strategy, two BOX units were connected around a simple linear aromatic plate forms, such as bithiophene and EDOT-Thiophene-EDOT unit as spacer. Interestingly, these systems are able to commute between 3 different metastable states in a stepwise manner with all kinds of stimulations. Going further, in order to promote the metastable states, it was possible to increase the number of BOX by connecting three of them on more elaborated pi systems which are potentially able to exhibit up to four discriminate metastable states. Complementary to that, a second strategy was to synthesize various nitrogen ligands functionalized by at least one BOX unit and their coordination chemistry with zinc and ruthenium metals. The response of the ligands as well as their corresponding complexes under photo, electro and acidic stimulation were also investigated and fully characterized

Texto completoThis work is devoted to the synthesis, characterization, and photophysical studies of novel luminescent molecular switches and thermoelectric molecular wires. After a bibliographic survey concerning the modulation of near-infrared (NIR) luminescence with lanthanide ions, the synthesis of macrocyclic lanthanide-based systems bearing two photochromic units is described. The key complexes are fully characterized and their photophysical studies are demonstrated. These complexes display enhanced optical and chemical stability and show photo-tunable emission in the visible and the NIR regions. The third part of this work aims at obtaining multifunctional lanthanide-based switches. The synthesis of new lanthanide complexes bearing three photochromic units and a redox-active ruthenium-based moiety is described. Full characterization of the complexes are further demonstrated. The photophysical studies reveal the possibility to switch the NIR luminescence of the ytterbium(III) ion both optically and electrochemically. The fourth part of this manuscript describes the synthesis and characterization of robust lanthanide-based complexes toward anticounterfeiting technologies. It is shown that switching europium(III) and ytterbium(III) luminescences in the visible and NIR regions could occur in both solution and solid polymer matrices. The last part of this work concerns molecular wires for thermoelectric applications. It describes the synthesis and characterization of promising transition metal complexes that should display quantum interferences in order to reach thermoelectric properties in molecular devices

This thesis presented the electrochemical studies of linear multinuclear metal string complexes and switchable porphyrin dimers. Cyclic voltammetry (CV) is used to determine the half-wave potential(E1/2) of the metal string complexes. UV-Vis-NIR spectro-electrochemistry is used to confirm the formal potential(Eo’), the number of electron transfer in each redox process, and the oxidation states of metal string complexes. In the linear multinuclear metal string complexes, based on the electronchemical results and X-ray crystal structures, we are able to determine the oxidative or reductive centers for the electrochemical processes. We found that the redox couples in metal complexes are influenced by the number of metal ions, the oxidation states of the metal, the nature of the ligands and a variety of solvents. It is well known that the reversible conversion between quinone and hydroquinone can be achieved by chemical or electrochemical methods. Incorporation of a quinone unit into the central part of a porphyrin dimer via acetylene linkers would allow the interporphyrin interaction to be switched off and on in a controllable fashion and this type of molecules may have the potential for the application in switchable molecular wires.

Herein, we synthesized a TTF contained molecular clip 1a. Under acidic condition, the known molecular clip 2 underwent a condensation reaction with 2-thioxo-1,3-dithiole. The resulting product 3 was then modified on the phenolic groups with triethylene glycol monomethyl ether tosylate to get molecular clip 5a. 5a was treated with Hg(OAc)2 to convert thione into ketone (6a). Then the resulting molecular clip 6a was reacted with 1,3-dithiole-2-thione in presence of P(OEt)3 to afford 1a. We found such TTF contained molecular clip that forms a macrocycle – molecular clip complex with a electronic complementary macrocycle. Four different sets of external stimuli – the K+/[2,2,2]cryptand, NH4+/Et3N, (p-PhBr)3NSbCl6/Zn pairs and heating/cooling cycles – allow the movement of this molecular switch to be controlled between its threaded and unthreaded states. The macrocycle – molecular clip complex not only considered as a quadruply controllable molecular switch but also can be operated by three of these stimuli as a three-input molecular NOR-functioning logic gate that may be monitored by UV-Vis spectroscopy.
