  1. 1. Fullerene γ-Cyclodextrin Complexes

    University dissertation from Chalmers University of Technology

    Author : Thomas Andersson; Chalmers tekniska högskola.; Chalmers University of Technology.; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; fullerene; C60; C70; Buckminsterfullerene; a-cyclodextrin; b-cyclodextrin; g-cyclodextrin; host-guest; FAB LSIMS; aggregates; ring-currents;

    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

  2. 2. Electron transfer and fragmentation in fullerene collisions

    University dissertation from Stockholm : Fysikum

    Author : Henning Zettergren; Stockholms universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fullerene; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : In this thesis, we present results from detailed gas phase studies of intrinsic properties of fullerenes (C60) and clusters of fullerenes as probed by slow multiply charged (atomic or cluster) ions in combination with coincidence time-of-flight mass spectrometry. We have investigated the structures, stabilities, and the electron mobilities of multiply charged clusters of fullerenes, (C60)nr+ (r=2-5). READ MORE

  3. 3. New Fullerene Materials Obtained in Solution and by High Pressure High Temperature Treatment

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Alexandr Talyzin; Uppsala universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; fullerene; solution; high pressure; Raman spectroscopy; polymerisation; XRD; Kemi; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : Crystallization of C60 and C70 from organic solution often leads to the formation of new solvates and other fullerene compounds. In the present thesis, a number of such solvates were obtained and their phase transitions studied using in situ "in solution" techniques. READ MORE

  4. 4. Evolution and control of the three dimensional functional microstructure of Polymer:Fullerene photovoltaic blends

    University dissertation from Chalmers University of Technology

    Author : Olof Bäcke; Chalmers tekniska högskola.; Chalmers University of Technology.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer:fullerene film; organic solar cell; transmission electron mi- croscopy; tomography; in situ; thermal degradation; fullerene crystals; crosslinking;

    Abstract : Polymer:fullerene bulk-heterojunction thin films show great promise for use as active layers in organic solar cells. However, their low thermal stability is a hindrance that complicates the manufacturing and influences the lifetime of devices. READ MORE

  5. 5. Fabricating designed fullerene nanostructures for functional electronic devices

    University dissertation from Umeå : Umeå universitet

    Abstract : A long-term goal within the field of organic electronics has been to developflexible and functional devices, which can be processed and patterned withlow-cost and energy-efficient solution-based methods. This thesis presents anumber of functional paths towards the attainment of this goal via thedevelopment and demonstration of novel fabrication and patterningmethods involving the important organic-semiconductor family termedfullerenes.
