  1. 11. Functional Cyclic Carbonate Monomers and Polycarbonates : Synthesis and Biomaterials Applications

    Författare :Jonas Mindemark; Tim Bowden; Andrew Dove; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA condensation; gene delivery; ionomers; polyplexes; self-assembly; amphiphiles; biodegradable; biological applications of polymers; transfection; cyclic carbonate monomers; polycarbonates; semicrystalline polymers; click chemistry; triazoles; cycloaddition; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Sammanfattning : The present work describes a selection of strategies for the synthesis of functional aliphatic polycarbonates. Using an end-group functionalization strategy, a series of DNA-binding cationic poly(trimethylene carbonate)s was synthesized for application as vectors for non-viral gene delivery. LÄS MER

  2. 12. Reaching Kinetic Selectivities : In Pursuing Novel Ternary Oxide Coatings, and Beyond

    Författare :Sebastian Öhman; Mats Boman; Tobias Törndahl; Maarit Karppinen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; CVD; coatings; kinetics; crystallization; nucleation; diffusionless; Al2TiO5; oxides; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : Kinetically driven synthesis pathways have the potential to allow new ways to develop materials and phases with much-improved properties. This particularly concerns metastable and multicomponent phases that require a selective kinetic targeting during the synthesis to circumvent the formation of thermodynamically stable products.

  3. 13. Low-coordinate Organosilicon Chemistry : Fundamentals, Excursions Outside the Field, and Potential Applications

    Författare :Muhammad Rouf Alvi; Henrik Ottosson; Joji Ohshita; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organosilicon; silene; silaaromatics; silenolate; hypersilyl group; alcohol protection; molecular switch; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

    Sammanfattning : This thesis reports on unsaturated silicon compounds, as well as excursions from these into germanium chemistry, single molecule electronics, and silyl protective group chemistry. Both experimental and computational investigations were performed. LÄS MER

  4. 14. Chemistry of Carbon Nanostructures : Functionalization of Carbon Nanotubes and Synthesis of Organometallic Fullerene Derivatives

    Författare :Claes-Henrik Andersson; Helena Grennberg; Nazario Martín León; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbon nanotubes; Fullerenes; Purification; Functionalization; Organometallic complexes; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

    Sammanfattning : This thesis is based on two main parts. The first part concerns purification and functionalization of carbon nanotubes (papers I-III), and the second part is related to the synthesis of organometallic fullerene derivatives (papers IV-VII): Two oxidative methods involving aqueous nitric acid were compared with respect to their capability to introduce carboxylic groups into single walled carbon nanotubes, and several literature methods for esterification and amidation of these groups have been evaluated with focus on efficiency and reproducibility in forming covalently functionalized products soluble in organic media.

  5. 15. Transition Metal Catalysis for Selective Synthesis and Sustainable Chemistry

    Författare :J. Johan Verendel; Pher G. Andersson; Reko Leino; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Catalysis; Transition metals; Asymmetric catalysis; Hydrogenation; Sustainable chemistry; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

    Sammanfattning : This thesis discusses the preparation and use of transition-metal catalysts for selective organic chemical reactions. Specifically, two different matters have been studied; the asymmetric hydrogenation of carbon-carbon double bonds using N,P-ligated iridium catalysts and the metal-catalyzed transfer of small molecules from biomass to synthetic intermediates.
