  2. 1. Angle-Dependent Electron Spectroscopy Studies of C60 Compounds and Carbon Nanotubes

    Author : Joachim Schiessling; P. A. Brühwiler; J. Nordgren; Hans-Peter Steinrück; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fullerenes; C60; K3C60; multi-walled carbon nanotubes; molecules; clusters; electron spectroscopy; synchrotron radiation; x-ray absorption; x-ray emission; molecular orbitals; charge transfer; electron correlation; surface physics; Fysik; Physics; Fysik;

    Abstract : Fullerenes have been shown to constitute a prototypical building block for truly nanometer-sized devices and exotic nanounit-based materials, e.g., high-temperature superconductors. READ MORE

  4. 2. Studies of carbon nanomaterials based on fullerenes and carbon nanotubes

    Author : Agnieszka Iwasiewicz-Wabnig; Bertil Sundqvist; Eleanor E.B. Campbell; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fullerenes; carbon nanotubes; fullerene polymers; intercalation compounds; high pressure; Raman spectroscopy; X-ray diffraction; atomic force microscopy; phase transitions; Material physics with surface physics; Materialfysik med ytfysik;

    Abstract : Materials based on fullerenes and carbon nanotubes are very much different from most “traditional” materials, primarily because they are built from nanosized molecules with highly symmetry-dependent properties. Being the subject of a very active research field over the last twenty years, carbon nanostructures proved to be indeed extraordinary. READ MORE

  5. 3. Hydroarylation of Fullerene C60 Using Arylboronic Acids via Rhodium Catalysis : Improving the Outcomes and Simplifying the Conditions

    Author : Merve Ergun Dönmez; Helena Grennberg; Luke Odell; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fullerene; C60; hydroarylation; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : Hydroarylation with arylboronic acids is one of the functionalization methods for synthesis of modified fullerenes. In this work, we provide a fast and reproducible one-phase method for hydroarylation of fullerene using boronic acids and an analytical HPLC method that efficiently separates unreacted C60 and product from a hydroarylation reaction mixture as well as a fulleropyrrolidine reaction mixture.

  6. 4. Fullerene γ-Cyclodextrin Complexes

    Author : Thomas Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; C60; a-cyclodextrin; aggregates; FAB LSIMS; Buckminsterfullerene; g-cyclodextrin; b-cyclodextrin; ring-currents; fullerene; host-guest; C70;

    Abstract : The fullerenes, C60 and C70, can form inclusion complexes with .gamma.-cyclodextrin as the host. The complexes are formed by refluxing a water solution of . READ MORE

  7. 5. Carbon Nanostructures – from Molecules to Functionalised Materials : Fullerene-Ferrocene Oligomers, Graphene Modification and Deposition

    Author : Michael Nordlund; Helena Grennberg; Mogens Brøndsted Nielsen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fullerenes; Graphene; Deposition; Functionalization; Organometallic complexes; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : The work described in this thesis concerns development, synthesis and characterisation of new molecular compounds and materials based on the carbon allotropes fullerene (C60) and graphene.A stepwise strategy to a symmetric ferrocene-linked dumbbell of fulleropyrrolidines was developed.
