1. NMR Investigations of Host-Guest Complexes and Their Dynamic Properties
Abstract : This thesis discusses several different methods offered by solution and solid state nuclear magnetic resonance for investigation of host-guest complexes and their constituents. The presented methods were used especially (but not exclusively) to address rotational dynamics of the bound guest in different molecular systems. READ MORE

2. (Photo)electrochemical Water Oxidation: From Catalysis to Functional Device
Abstract : The key challenge within artificial photosynthesis is achieving efficient electro- or photo-driven water oxidation catalysis, a necessary process to supply the protons for the reduction reactions, thereby enabling solar fuel production. To facilitate efficient water (photo)electrolysis for solar fuel production, this thesis focuses on two aspects: 1) elucidating the O-O bond formation mechanism and developing efficient, stable, and economical water oxidation catalysts (WOCs); 2) exploring stable, low-cost, light-absorbing photoanode materials that have suitable band structures and excellent charge diffusion properties.

3. Host-Guest Interactions for Structural Analysis of Organic Molecules : Development of new Tools for Stereochemical Characterization
Abstract : The focus of this thesis is on the development of molecular tweezers as host-guest systems for stereochemical characterization of small organic molecules.There are two central problems to stereochemical characterization of small molecules. READ MORE

4. Selectivity in Host-Guest Chemistry
Abstract : This thesis describes host-guest complexes with the use of a biphenyl crown ether or cyclodextrin as host. Complexes between the biphenyl crown ether and salts form phenylalanine esters were studied. READ MORE

5. Improving Tröger's Base Chemistry : Developing the Chemistry of Tröger's base
Abstract : The Tröger’s base framework has been implemented in two different receptors. The first of these receptors, incorporating two 18-crown-6 moities, was used as a host in a binding study together with a sieries of bisammonium salts that yielded different binding constants that were then used as a benchmark to compare different computational methods (Molecular Mechanics (MM) and Density Functional Theory (DFT)) in predicting the correct results where the MM methods proved more effective.
