1. Homochiral crystals for selective synthesis
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
2. A molecular guide to efficient charge transport : Coordination materials for photovoltaic cells
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
3. Cation Conduction and Coordination in Carbonyl-Containing Compounds : Li+ Transport in Alternative Polymer Electrolyte Host Materials
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
4. Using Molecular Dynamics Simulations to Explore Critical Property Relationships in Polymer Electrolytes : Polarity, Coordination, Ionic transport, Ion-pairing, and Ion-ion Correlations
Sammanfattning : While ion transport in solid polymer electrolytes (SPEs) has been explored for decades, there still remains controversies about its fundamental properties, often correlated with gaps between experimental and computational studies. Using molecular dynamics simulations to understand the complex transport mechanisms and also to fill these gaps is the main goal of this thesis. LÄS MER
5. Polymer Bound Water-Soluble Metal Phosphine Complexes-Preparation, Characterisation and Catalytic Application
Sammanfattning : Four new water-soluble phosphines have been prepared by utilising water-soluble polymers as charge carrying units. Coupling of methyl-4-(diphenylphosphino)-benzyl-amine or 4-diphenylphosphino benzaldehyde to poly-acrylic acid and poly-ethylene imine, respectively, afford the ligands PAA-PNH and PEI-PNH. LÄS MER
