1. Interrogating Diffusional Mass and Charge Transport in Catalytic Metal-Organic Frameworks
Sammanfattning : Molecular catalysts are efficient and selective for the electrochemical conversion of small molecules for energy conversion. Application of molecular species in a large-scale industrial setting requires stabilization in a heterogeneous support material. LÄS MER
2. Novel Approaches to Phosphorus-containing Heterocycles and Cumulenes
Sammanfattning : Fast development in all areas of life and science over the last 50 years demands versatile, energy efficient and cheap materials with specific but easily tuneable properties which can be used for example in organic light emitting diodes (OLEDs), thin-film transistors, photovoltaic cells, etc. This thesis is devoted to the development of novel synthetic approaches to molecules with potential applications in the field of molecular electronics.

3. Iron, Manganese and Iridium Complexes From Models of RNR and Catalase to Water Oxidation
Sammanfattning : The focus of this thesis has been synthesise and study metal complexes that mimic the structure and function of the active site in two particular metalloenzymes, ribonucleotide reductase (RNR) and manganese catalase (MnCAT). These two metalloenzymes both have two transition metals ions in the cofactor: two manganese ions in MnCAT and either two iron, iron-manganese or two manganese ions in RNR. LÄS MER
4. Synthetic [FeFe] Hydrogenase Active Site Model Complexes
Sammanfattning : [FeFe]-Hydrogenases (H2ases) are metalloenzymes that can catalyze the reversible reduction of protons to molecular hydrogen as part of the metabolism of certain cyanobacteria and green algae. Due to the low availability of the enzyme, synthetic complexes that mimic the natural active site in structure, function and activity are highly sought after. LÄS MER
