Energy and Charge Transfer Processes in Biomimetic Molecular Aggregates

Efficient transfer of electronic excitation energy is a key process in molecular electronics. In our group, we investigate molecular aggregates and small oligomeric model systems to shed light on the underlying physical properties that determine the efficiency and the range of the transport process.
