  1. 1. Organic Azides : Functional Molecules and Materials

    Författare :Giampiero Proietti; Peter Dinér; Per I. Arvidsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; perfluorinated Aromatic Azide; Photoactivatable; fluorophores; aggregation-induced emission; sulfonimidamides; sulfoximes; chiral auxilary; organogel; azides reduction; Ni-B; Kemi; Chemistry;

    Sammanfattning : The work presented in this thesis stems from the chemistry of the azido group, and more specifically from the unique reactivity of perfluorinated aromatic azides and how to use this reactivity to access new types of molecules to enable new applications in asymmetric synthesis and materials.In the first section of this thesis, a photoactivatable fluorescence probe is presented, where the non-luminescent azide was activated via a UV-light-promoted intramolecular N–H insertion reaction forming a fluorescence emitter.

  2. 2. Synthesis of Organic Chromophores for Dye Sensitized Solar Cells

    Författare :Daniel Hagberg; Licheng Sun; Olof Ramström; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic Chromophores; Dye Sensitized Solar Cells; Organic chemistry; Organisk kemi;

    Sammanfattning : This thesis is divided into four parts with organic chromophores for dye sensitized solar cells as the common feature and an introduction with general concepts of the dye sensitized solar cells. The first part of the thesis describes the development of an efficient organic chromophore for dye sensitized solar cells. LÄS MER

  3. 3. Organic Reactions i Organised Media

    Författare :TOMASZ WITULA; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nucleophilic substitution; mesoporous material; microemulsion; silica; lipase; Liquid crystal; alumina; entrapment.; heterogenized; titania; organic synthesis;

    Sammanfattning : A common problem in synthetic organic chemistry is reactant incompatibility between lipophilic organic compounds and inorganic salts. The thesis reports an investigation of some organic reactions, involving incompatible substrate and nucleophile, performed in liquid crystalline phases and also in slurries of mesoporous materials with different symmetry.

    Sammanfattning : New strategies are needed to counter the growing problem of bacterial resistance to antibiotics. One such strategy is to design compounds that target bacterial virulence, which could work separately or in concert with conventional bacteriostatic or bactericidal antibiotics. LÄS MER

  5. 5. Structure-Based Design and Synthesis of Protease Inhibitors Using Cycloalkenes as Proline Bioisosteres and Combinatorial Syntheses of a Targeted Library

    Författare :Fredrik Thorstensson; Ingemar Kvarnström; Charles Hedgecock; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic chemistry; organic synthesis; combinatorial synthesis; metathesis; olefin metathesis; thrombin; HCV; NS3; protease; proline isosteres; inhibitor; Organic synthesis; Organisk syntes;

    Sammanfattning : Structure-based drug design and combinatorial chemistry play important roles in the search for new drugs, and both these elements of medicinal chemistry were included in the present studies. This thesis outlines the synthesis of protease inhibitors against thrombin and the HCV NS3 protease, as well as the synthesis of a combinatorial library using solid phase chemistry. LÄS MER
