2. Tuning of Energy and Electron Transfer Rates in Donor-Bridge-Acceptor Systems
Abstract : The intramolecular processes of Donor-Bridge-Acceptor (D-B-A) systems have been investigated by spectroscopic methods. The systems consist of porphyrin donors and acceptors linked by oligo-p-phenyleneethynylene bridges. READ MORE

3. 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.

4. Porphyrin-Based Donor-Bridge-Acceptor Systems: Intrinsic Excited State Deactivation and Intramolecular Energy/Electron Transfer Reactions
Abstract : Intramolecular energy and electron transfer reactions have been studied between porphyrin donor and acceptor moieties. The porphyrin units are covalently linked together by one of three different bridging chromophores to constitute the series of D-B-A systems. READ MORE

5. Emerging Energy Possibilities
Abstract : This Thesis presents a thorough study of the electron transfer (ET) processes, both inter-molecular - between dyes for dye-sensitized solar cells (DSSCs), and intra-molecular - in porphyrin based electron donor-bridge-electron acceptor model systems. The focus has been on charge separation and subsequent re-combination in the femtosecond-nanosecond range in both systems. READ MORE
