1. Synthesis of Covalently Linked Diporphyrins: Model Compounds for Intramolecular Energy and Electron Transfer
Abstract : Three series of donor-bridge-acceptor compounds have been synthesized to probe the influence of various bridge chromophores on energy and electron transfer. The donor-bridge-acceptor compounds in each series comprise two different porphyrins, acting as donor and acceptor, covalently linked by bridge chromophores. READ MORE

2. Influence of Bridge Structures on the Electron Transfer in Donor-Acceptor Systems
Abstract : In this Thesis, porphyrin-based donor-acceptor systems have been used to study photoinduced electron transfer processes. Principally, two different sets of systems have been investigated. READ MORE

3. Studies of Biomimtic Oxidations and Racemizations
Abstract : This thesis deals with studies of ruthenium-catalyzed hydrogen transfer reactions for oxidations and racemization.Through optimisation of the substrate-selective redox catalyst, the electron and proton transfer mediator (a benzoquinone derivative), and the oxygen-activating metal macrocycle a highly efficient biomimetic oxidation of secondary alcohols was obtained.

4. Triplet Excitation Energy Transfer in Donor-Bridge-Acceptor Systems: Experimental and Theoretical Investigations
Abstract : This thesis is a contribution to the understanding of bridge mediation of electron exchange processes in Donor-Bridge-Acceptor (D-B-A) systems. The field of research is relevant for the development and optimization of dye-sensitized solar cells, artificial photosynthesis, and the possible future development of molecular electronic devices.

5. Structure of Self-Assembled Monolayers on Gold Studied by NEXAFS and Photoelectron Spectroscopy
Abstract : Self-assembled monolayers (SAMs) provide well-defined and ordered films of molecules spontaneously chemisorbed on a surface. By designing molecules with desired functionalities, such molecular film can be interesting for a range of applications from molecular electronics to catalysis. READ MORE
