Inhomogeneous 1H NMR spin-lattice relaxation in the organic superconductor κ-(BEDT-TTF)2-Cu[N(CN)2]Br
The two-dimensional superconductors based on the organic molecule “ET” have been an active area of research since their discovery over two decades ago. The member of this family with the highest critical temperature, κ-(ET)2Cu[N(CN)2]Br (Tc=11.7 K), has seen renewed interest since the observation …

Synthesis of new substituted organosulfur donors for the preparation of conductive and multifunctional materials
… three main type of compounds: i) bridged dimeric BEDT-TTF donors (chapter 2), ii) enantiopure substituted EDT-TTF donors with hydrogen bonding functionalities (chapter 3) and iii) BEDT-TTF substituted ligands and their ability to form multifunctional materials (chapter 4). In chapter 2 the …

Première investigation du diagramme de phase du composé organique [kappa]-[BEDT-TTF][indice inférieur 2]Cu[N(CN)[indice inférieur 2]]Cl avec la technique de mesure ultrasonore
… difficiles. Cependant, la famille des [kappa]-[BEDT-TTF][indice inférieur 2]X où X est un anion présente l'avantage d'avoir de grandes similarités avec les supra-conducteurs à haute température critique tout en étant à de faibles énergies. Ce travail est une étude ultrasonore du composé …

Determination of the Magnetic Structure of the Antiferromagnetic State of the Organic Superconductor Kappa-(bedt)(2)copper Dicyanamide Chloride Using Nuclear Magnetic Resonance and Magnetometry
… state of the organic superconductor kappa-(BEDT-TTF)2Cu[N(CN) 2]Cl. Various other magnetization and NMR studies have suggested that there is antiferromagnetic ordering of the electron spins in the magnetic state, but the detailed ordering was not understood. Our 13C NMR resonance frequency …

Anilate-based Functional Molecular Materials with Conducting and Magnetic Properties
… molecular conductors obtained combining the BEDT-TTF organic donor and the [Fe(Cl2An)3]3- metal complex as conducting and magnetic building blocks, respectively. The correlation between the crystal structure and conductivity behavior is reported. Finally, in Chapter 5, the crystal structures …

The preparation of organosulfur derived electron transfer salts
… on the bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF or ET) framework, and are produced using the technique of electrocrystallisation. In attempts to control the crystal packing arrangements observed, a number of approaches have been explored including the incorporation of chirality, hydrogen …

Transport properties in the vicinity of Mott insulators
… by the recently created organic compound r-(BEDT-TTF)2- Cu2(CN)3, we study a particular spin liquid where there is a spinon Fermi surface coupled to a U(1) gauge field. While still a charge insulator, this model has many metallic-like properties. We first develop a quantum Boltzmann equation …

Strong electronic correlations in low-dimensional systems
… We apply this method to two organic crystals: TTF-TCNQ and (BEDT-TTF)_2 I_3. Having the parameters of the former we solve a long standing problem in the interpretation of its spectra. One of the most successful methods to treat strongly correlated systems is DMFT. It provides a good …
