1. Tuning of Energy and Electron Transfer Rates in Donor-Bridge-Acceptor Systems
Sammanfattning : 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. LÄS MER
2. Energy and Electron Transfer in Porphyrin-Based Donor--Bridge--Acceptor Systems
Sammanfattning : The photophysical properties of supramolecular donor--bridge--acceptor systems have been investigated by spectroscopic and quantum mechanical methods. The systems consist of porphyrin donor and acceptor moieties linked by bridging chromophores of varying excitation energy, and are shown to be geometrically well-defined in terms of length and rotational conformation.

3. Exciton coupling and energy transfer in perylene-based systems
Sammanfattning : Understanding the nature of photoinduced processes in organic molecules is essential for the design and synthesis of compounds with desired photochemical properties. This dissertation aims for gaining knowledge and mechanistic understanding of energy transfer in perylene-based systems. LÄS MER
4. Energy Transfer Patterns in Photosynthetic Antenna System of Purple Bacteria
Sammanfattning : Steady state and time-resolved absorption and fluorescence spectroscopy have been used to investigated the energy transfer in photosynthetic purple bacteria. Picosecond light pulses were used in measurements of Rb. LÄS MER
5. Synthesis and Energy Transfer Studies of a Donor-Host-Acceptor Triad
Sammanfattning : This dissertation describes the synthesis of a donor-host-acceptor triad, D-H-A, and its self-assembly into a well-ordered dimer. The energy transfer (EnT) properties of D-H-A as it is, in the presence of a variety of guest molecules and in the dimeric form are presented. LÄS MER
