    Organometallic chemistry of low-valent lanthanides: unusual oxidation states and magnetic sandwiches

    Séminaire du Dr Grégory Nocton (Ecole Polytechnique)
    Abstract :
    Organolanthanide complexes are an interesting class of organometallic compounds that have been developed in the 1950’s and that now concern most of the rare earths in their trivalent and divalent states. The applications for such compounds are numerous for single electron transfer reactivity and also because of their optical and magnetic...

    From classic BODIPY to multifunctional Wazaby platform

    Séminaire du Prof. Ewen Bodio (ICMUB – Université Bourgogne-Franche-Comté)
    Abstract :
    BODIPY is one of the most versatile fluorophore (high quantum yield, high brightness, stable, synthesizable at gram-scale…), but its emission in the visible region of light spectrum and its poor water-solubility hamper its use for in vivo applications. This lecture will describe how the optimization a BODIPY-based...

    Abstract :
    Non-covalent interactions are crucial and of increasing interest in “supramolecular electrochemistry” concerning redox properties of supramolecular assemblies in solution. The importance of halogen bonding, an only recently described non-covalent interaction, is nowadays fully recognized. In this context we have shown the electrochemically...

    Abstract :
    Dipyrrins are bis-pyrrolic derivatives that can be rather easily synthesized and functionalized, forming monoanionic chelates under mild basic conditions. These features make them interesting ligands for the elaboration of discrete and infinite metal-organic architectures. In particular, our efforts have centered on...
