Les séminaires CulturChem

    • Molecular Behavior in a Small Space

      Séminaire du Pr Julius Rebek, Jr (The Scripps Research Institute and Shanghai University)
      Abstract
      This lecture describes molecular behavior in synthetic receptors that completely surround their targets: encapsulation complexes. Topics include the new forms of stereochemistry, amplified interactions, chiral spaces and reactivity of molecules confined to a small space. The composition of the capsule...

    • Breaking the limits in investigating Glycan-Protein Interactions by using NMR

      Séminaire du Dr Jésus Jimenez Barbero (CIC bioGUNE, Spain)
      Abstract
      Molecular recognition by specific targets is at the heart of the life processes. In recent years, it has been shown that the interactions between proteins (lectins, enzymes, antibodies) and carbohydrates mediate a broad range of biological activities, from fertilization, embryogenesis, and tissue maturation, to pathological processes...

    • Redox-active self-assembled cages

      Séminaire du Pr Marc Sallé (MOLTECH-Anjou, UMR CNRS 6200, Univ. Angers)
      Abstract
      While molecular cages are often challenging to prepare through covalent chemistry procedures, the metal-driven self-assembly methodology allows a straightforward access to a wide variety of discrete architectures. The resulting cavities offer promising opportunities for applications in host-guest chemistry. In this context...

    • 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...

    • Chemical Biology Tools to Perceive and Perturb Carbohydrates and Carbohydrate Processing Enzymes in Living Systems

      Séminaire du Pr David Vocadlo (Simon Fraser University) - Amphi 45B
      Abstract
      The carbohydrate structures found in every kingdom of life are emerging as a frontier area of chemical biology. I discuss our efforts to create new chemical biology tools for studying these structures and the enzymes that process them within cells and in animal models. Topics will be selected from the synthesis and deployment...

    • New Phospha-helicenes: Synthesis and Applications in Asymmetric Catalysis

      Séminaire du Dr Arnaud Voiturier (CNRS-ICSN, Gif-sur-Yvette)
      Abstract
      Over the past few years, helicenes have attracted considerable attention due to their wide potential, notably in materials science. However, molecular scaffolds with helical chirality have been rarely used for building phosphorus ligands and catalysts. In this context, our goal was to access unprecedented chiral auxiliaries for organo-...

    • Supramolecular Transition metal catalysis: control of activity and selectivity by second coordination sphere

      Séminaire du Pr Joost Reek (University of Amsterdam) - Amphi 45B
      Abstract
      The interface between supramolecular chemistry and transition metal catalysis has received surprisingly little attention in contrast to the individual disciplines. It provides, however, novel and elegant strategies that lead to new tools for the search of effective catalysts, and as such this has been an important research theme...

    • 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...
