    Towards [0n] paracyclophanes as templates for the synthesis of nanotubes

    Muster, Ludwig ; Jenny, Titus (Dir.) ; Bochet, Christian (Codir.)

    Thèse de doctorat : Université de Fribourg, 2007 ; no 1548.

    Today, nanotechnology has found a great interest in research areas of different scientific fields. Indeed, nanoparticles and nanodevices possess new and promising properties for a lot of applications. Chemistry is useful in preparation of such nanometer sized systems because she allows a construction atom by atom, also called "bottomup" approach. A rational synthesis of carbon nanotubes was...

    Development of iron catalysts for hydrogenation and polymerization

    Raemy, Manuel ; Jenny, Titus (Dir.) ; Bochet, Christian (Codir.)

    Thèse de doctorat : Université de Fribourg, 2003 ; no 1413.

    In the scope of this work, a series of new, easy to prepare iron hydrogenation catalysts have been introduced. Different aspects of this new hydrogenation catalysts such as iron source, activation reagent, substrates and efficiency were investigated. A ligand-free catalyst, prepared from an iron(II) chloride suspension activated with diisobutylaluminiumhydride (DIBAH), showed the highest...
