1. Ruthenium(II) Polypyridyl Complexes : Applications in Artificial Photosynthesis
Abstract : Molecular mimics of PS II, which consist of a photosensitizer linked to electron acceptors/donors, are attractive candidates for the conversion of solar energy into chemical energy. Several different classes of sensitizers have been studied and among these, ruthenium(II) polypyridyl complexes continue to attract major attention. READ MORE

2. DNA Interaction Dynamics of Ruthenium(II) Complexes
Abstract : DNA-binding of small synthetic ligands is of great importance in a number of different applications, from medicine to molecular biology. This thesis focuses on interactions between DNA and ruthenium(II) complexes, in particular the dimers [µ-bidppz(L)4Ru2]4+ (L=1,10-phenanthroline (P) or L=2,2-bipyridine (B)). READ MORE

3. DNA Interactions with Chiral Polyaza-aromatic Ruthenium(II) Complexes
Abstract : The binding to DNA of a series of chiral ruthenium complexes is studied with optical spectroscopy techniques, including isotropic absorption, linear dichroism (LD) and emission anisotropy as well as steady-state and time-resolved luminescence. The thesis focuses on the ìlight-switchî complex [Ru(phen)2dppz]2+ which binds to DNA by intercalation and luminesces when bound to DNA but not in pure buffer solution (phen=1,10-phenanthroline; dppz=dipyrido[3,2-a:2',3'-c]phenazine).

5. Tuning of the Excited State Properties of Ruthenium(II)-Polypyridyl Complexes
Abstract : Processes where a molecule absorbs visible light and then converts the solar energy into chemical energy are important in many biological systems, such as photosynthesis and also in many technical applications e.g. photovoltaics. READ MORE
