  2. 2. Cation Conduction and Coordination in Carbonyl-Containing Compounds : Li+ Transport in Alternative Polymer Electrolyte Host Materials

    Författare :Therese Eriksson; Daniel Brandell; Jonas Mindemark; Claudio Gerbaldi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solid polymer electrolytes; Lithium ion batteries; Ion transport; Polyester; Polycarbonate; Polyketone; Ion coordination; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : The field of solid polymer electrolytes (SPEs) used to create safer lithium-ion batteries has been dominated by polyethylene oxide (PEO) since the discovery of its ion-conducting properties in the 1970s. In this thesis, as an alternative, the ion coordination and conduction properties of SPEs based on polyketones, polyesters and polycarbonates are investigated. LÄS MER

  3. 3. Homochiral crystals for selective synthesis

    Författare :Theonitsa Kokoli; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Absolute asymmetric synthesis; total spontaneous resolution; optical activity; coordination compounds; coordination polymers; photoisomerization; enantioselective sulfide oxidation; single crystal X-ray crystallography; co-crystallization of diastereomers;

    Sammanfattning : Six new coordination compounds were prepared from monodentate sulfide ligands and copper(I) halides and their crystal structures were determined by single-crystal X-ray diffraction. The aim was to prepare coordination polymers that crystallize as conglomerates in order to use them in total spontaneous resolution. LÄS MER

  4. 4. A molecular guide to efficient charge transport : Coordination materials for photovoltaic cells

    Författare :Hannes Michaels; Marina Freitag; Aldo Di Carlo; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coordination chemistry; energy conversion; photovoltaics; charge transport;

    Sammanfattning : Emerging solar energy conversion and energy storage technologies play a vital role in solving the present energy crisis and achieving carbon net zero. Currently, they are limited by the use of inefficient, unstable and expensive charge transport materials. LÄS MER

  5. 5. Breaking the symmetry: creation and transfer of optical activity via total spontaneous resolution and stereoselective reactions

    Författare :Susanne Olsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; absolute asymmetric synthesis; enantioselective reactions; chirality; spontaneous resolution; conglomerate; organometallic chemistry; coordination compounds; attritionenhanced deracemisation; polymorphism; organolithium compounds; single-crystal X-ray crystallography;

    Sammanfattning : The generation of optical activity from achiral or racemic precursors – absolute asymmetric synthesis – is discussed in relation to the origin of biomolecular homochirality but is also often (incorrectly) regarded as being impossible. One approach to absolute asymmetric synthesis is the use of compounds that form chiral crystals. LÄS MER
