2. Ultrafast Dynamics in Ground and Excited States of Porphyrin Molecules
Abstract : This thesis describes inter and intramolecular dynamics in porphyrin molecules. To create a basis for understanding the energy and electron transfer processes in photosynthesis, the ultrafast dynamics of monomeric chlorophyll a, chlorophyll b and bacteriochlorophyll a were studied with ultrashort laser pulses.

3. Molecular Trees for Collecting Sunshine -Monitoring and Controlling Energy Transfer in Dendrimers
Abstract : A continuing use of fossil fuels will accelerate global warning and result in severe consequences for the environment and thereby also us. Development of alternative, sustainable and environmentally friendly energy sources is therefore crucial. One approach is to create an artificial photosynthetic system that converts sunshine into fuel (e.g. READ MORE
