Transition-Metal-Free Catalysts for the Sustainable Epoxidation of Alkenes: From Discovery to Optimisation by Means of High Throughput Experimentation

Warunee Lueangchaichaweng, Inge Geukens, Annelies Peeters, Benjamin Jarry, Franck Launay, Jean-Luc Bonardet, Pierre A. Jacobs, Paolo P. Pescarmona

Abstract: Transition-metal-free oxides were studied as heterogeneous catalysts for the sustainable epoxidation of alkenes with aqueous H2O2 by means of high throughput experimentation (HTE) techniques. A full-factorial HTE approach was applied in the various stages of the development of the…

Beyond simple AB diblock copolymers: application of bifunctional and trifunctional RAFT agents to PISA in water

Gaëlle Mellot, Patricia Beaunier, Jean-Michel Guigner, Laurent Bouteiller, Jutta Rieger, François Stoffelbach

The influence of the macro-RAFT agent architecture on the morphology of the self-assemblies obtained by aqueous RAFT dispersion polymerization in PISA is studied by comparing amphiphilic AB diblock, (AB)2 triblock and triarm-star shaped (AB)3 copolymers, constituted of N,N-dimethylacrylamide (DMAc…

Chemo–Phototherapeutic Effect of Polyoxometalate-Stabilized Gold Nanostars for Cancer Treatment

Juan Ramirez Henao, Souhir Boujday, Claire Wilhelm, Basile Bouvet, Somia Tomane, Ioanna Christodoulou, Daoming Sun, Guilhem Cure, Ferdaous Ben Romdhane, Antoine Miche, Anne Dolbecq, Pierre Mialane, Anne Vallée

A reduced polyoxometalate (POM) functionalized with bisphosphonate (BP) ligands possessing antitumoral properties was used to synthesize metallic gold nanostars (AuNSs) with high reproducibility through a silver-assisted seed growth method. Notably, this study is the first to employ a reduced…

Covalent shaping of polyoxometalate molecular films onto ITO electrodes for charge trapping induced resistive switching

Raphaël Salles, Wei Church Poh, Maxime Laurans, Florence Volatron, Antoine Miche, Sandra Alves, Christian Carino, Ludovic Tortech, Guillaume Izzet, Pooi See Lee, Anna PROUST

As nano-sized molecular oxides, polyoxometalates (POMs) hold great promise in non-volatile memory materials based on redox-active molecules. Materials processed from solution, by drop-casting, by embedding POMs in polymers, or using Layer-by-Layer deposition techniques have thus been reported and…

Highly Conductive Tungsten Suboxide Nanotubes

Cécile Huez, Maxime Berthe, Florence Volatron, Jean-Michel Guigner, Dalil Brouri, Lise-Marie Chamoreau, Benoît Baptiste, Dominique Vuillaume, Anna Proust

We demonstrate a high electron conductivity (> 10^2 S/cm and up to 10^3 S/cm) of tungsten suboxide W18O(52.4-52.9)(or equivalently WO(2.91-2.94)) nanotubes (2 to 3 nm in diameter, ca. micrometer long). The conductivity is measured in the temperature range 120 to 300K by a four probe scanning…

Chromium-Salophen as a Soluble or Silica-Supported Co-Catalyst for the Fixation of CO2 Onto Styrene Oxide at Low Temperatures

Matthieu Balas, Ludivine K/bidi, Franck Launay, Richard Villanneau

Addition of a soluble or a supported Cr III-salophen complex as a co-catalyst greatly enhances the catalytic activity of Bu 4 NBr for the formation of styrene carbonate from styrene epoxide and CO 2. Their combination with a very low co-catalyst:Bu 4 NBr:styrene oxide molar ratio 1:2:112 (…
