1. Fullerene γ-Cyclodextrin Complexes
Sammanfattning : 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 . LÄS MER
2. Electron transfer and fragmentation in fullerene collisions
Sammanfattning : 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). LÄS MER
3. Hydroarylation of Fullerene C60 Using Arylboronic Acids via Rhodium Catalysis : Improving the Outcomes and Simplifying the Conditions
Sammanfattning : 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.

4. New Fullerene Materials Obtained in Solution and by High Pressure High Temperature Treatment
Sammanfattning : 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. LÄS MER
5. Evolution and control of the three dimensional functional microstructure of Polymer:Fullerene photovoltaic blends
Sammanfattning : 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. LÄS MER
