1. Transition Metal Hydrides : Biomimetic Studies and Catalytic Applications
Sammanfattning : In this thesis, studies of the nature of different transition metal-hydride complexes are described. The first part deals with the enantioswitchable behaviour of rhodium complexes derived from amino acids, applied in asymmetric transfer hydrogenation of ketones. LÄS MER
2. Modeling Photofunctional Transition Metal Complexes
Sammanfattning : Transition metal complexes play a crucial role in solar energy conversion. These coordination compounds have promising applications in dye-sensitized solar cells and photocatalysis, with particular interest in solar fuel production. LÄS MER
3. Carbenes: The Gathering : Photophysics of Transition Metal Carbene Complexes
Sammanfattning : This thesis explores the photophysics of some transition-metal complexes (TMCs) which utilize N-heterocyclic carbenes as ligands. After a historical interlude which traces the development of the broader field of transition metal complexes and their photophysical investigations, there is an overview of theoretical concepts and the spectroscopic methods employed.

4. Transition Metal-Catalyzed Redox Reactions : A Journey from Homogeneous Ruthenium to Heterogeneous Palladium Catalysis
Sammanfattning : The first part of the thesis covers the development and utilization of electronically modified (pentaarylcyclopentadienyl)Ru-complexes in the racemization of secondary alcohols. This study revealed that the electronic properties of the substrate were the main factors dictating whether β-hydride elimination or hydride re-addition becomes the rate-determining step of the racemization process.

5. Microstructure aspects of transition metal carbide thin films
Sammanfattning : Transition metal carbides are important refractory materials used in many thin film applications. In this thesis, several transition metal carbides have been deposited using different chemical vapour deposition (CVD) and evaporation processes. In particular, the phase composition and microstructure of these carbide films have been studied. LÄS MER
