    Turning lead into gold: Materials and nanostructures in electrochemical energy conversion

    Séminaire du Pr Julien Bachmann (FAU, Erlangen-Nürnberg)
    Abstract
    One strategy for minimizing the use of expensive functional materials in energy conversion devices consists in accurately controlling the interface’s microscopic geometry. ‘Anodic’ nanoporous templates and atomic layer deposition yield structured electrode surfaces with a tunable geometry of ordered pores. Their diameter and length are...

    Photoredox Catalysis: Trifluoromethylation and Beyond

    Séminaire du Pr Munetaka Akita (Tokyo Institute of Technology, Yokohama)
    Abstract
    . Photoredox catalysis mediated by photo-sensitizers (e.g. [Ru(bipy)3]2+ and relevant Ir complexes) has attracted increasing attention as practical, green synthetic chemical processes, because they are visible light-promoted, redox-neutral reaction systems. Organyl radicals can be formally generated by 1e-oxidation and...

    Studies of Lanthanoid Single-Molecule Magnets

    Séminaire du Pr Colette Boskovic (The University of Melbourne)
    Abstract
    The slow magnetisation relaxation and quantum tunnelling exhibited by single-molecule magnets (SMMs) may see them as the basis of future molecular spintronics devices or quantum computers.  We are presently exploring the development of new lanthanoid-based SMMs that incorporate redox-active ligands.  Another focus is elucidation...

    Asymmetric Catalysis Induced by Visible Light: From Free Radical to Excited State Chemistry

    Séminaire du Pr Eric Meggers (Department of Chemistry, University of Marburg)
    Abstract
    The lecture will report on our progress to intertwine visible-light-activated chemistry with asymmetric catalysis. An unusual class of catalystis is employed which derive their chirality exclusively from a stereogenic metal center. Bis-cyclometalated chiral-at-metal iridium(III) and rhodium(III) catalysts provide...

    Advancing synthetic chemistry in biological media

    Séminaire du Pr Alain Wagner (Chimie BioFonctionnelle UMR 7199 Illkirch France)
    Abstract
    Our research focuses on the development of chemical reactions that are compatible with complex biological media. They are qualified as bioorthogonal when they can take place in a complex biological medium without distorting it, or as bio-specific when they touch only a precise part of it.
    Taking advantage of imaging...

    Transition de spin photo-induite : développements récents

    Séminaire du Prof Guillaume Chastanet (ICMCB, Université de Bordeaux)
    Abstract
    Depuis le début des années 80, la commutation optique de complexes de Fe(II) à conversion de spin a suscité un engouement notable puisqu’elle laissait envisager des processus ultrarapides, à l’échelle de la molécule. Nous verrons que la photocommutation ne se restreint plus aux composés à conversion de spin et que la conception...

    Functional PolyAromatics: a little flexibility in Molecular Recognition and Gold Complexes

    Séminaire du Prof Brigitte Bibal (ISM - UMR 5255, Université de Bordeaux)
    Abstract
    Our research aims to design modular polyaromatic compounds devoted to catalysis and molecular recognition. In this seminar, we will focuss on 9,10-diphenylanthracene and its unique photochemical and photophysical properties. Its switchable function was highlighted within a molecular cage that binds cations in an adjustable...
