1. Supramolecular chemistry based on redox-active components and cucurbit[n]urils
Sammanfattning : This thesis describes the host-guest chemistry between Cucurbit[7]uril (CB[7]) and CB[8] and a series of guests including bispyridinium cations, phenols and napthalenes. These guests are bound to ruthenium polypyridine complexes or ruthenium based water oxidation catalysts (WOCs). LÄS MER
2. Genes and Physiological Role of the Eukaryotic Nicotinamide Nucleotide Transhydrogenase
Sammanfattning : Nicotinamide nucleotide transhydrogenase (NNT, EC 1.6.1. LÄS MER
3. Electrochemical Studies of Redox Properties and Diffusion in Self-Assembled Systems
Sammanfattning : In this thesis electron transfer reactions and diffusion of redox molecules in three different types of self-aggregated structures are investigated. Electrochemistry was used to investigate the redox potential and diffusion coefficients for redox active molecules with different polarity. The first aggregate system studied was the micellar phase.

4. Ruthenium complexes and substituted polypyridines in photophysical and electron transfer studies
Sammanfattning : Organic molecules acting as electron acceptors and ligandsfor metal complexes were synthesized. N-alkylation of4,4'-bipyridine and nicotinamide yielded electron transport andacceptor molecules. By regioselective functionalization of2,2'-bipyridine (bpy), several novel ligand molecules wereobtained. LÄS MER
5. Biocatalysed redox reactions in aqueous and organic media
Sammanfattning : This thesis deals mainly with biocatalysed methods for stereoselective reduction. D-(S)-chlorolactic acid was produced by both microbial and electromicrobial reduction of chloropyruvate using whole cells of Proteus vulgaris and an artificial electron mediator. The electron donor was formate, hydrogen gas or the cathode in an electrochemical cell. LÄS MER
