Prof. Dr. Jan Behrends, FU Berlin: Spins at Work in Energy Conversion and Storage Devices Unpaired electron spins are unique local probes for elucidating photocurrent generation in organic solar cells as well as redox reactions in polymer batteries. EPR spectroscopy can thus be employed to analyse these processes, identify loss mechanisms, and eventually help developing strategies for improving the performance of devices for energy conversion and energy storage. The first part of the talk will address the role of electron spins in charging and discharging of organic radical batteries (ORBs). The second part of the presentation will give an overview about how EPR-based techniques in combination with optical excitation can usefully complement all-optical experiments in studying charge separation in materials for solar cells based on organic semiconductors.

Prof. Dr. Douglas Philp, University of St Andrews, UK In through the Out door – Creating responsive and dynamic networks using synthetic replicators The development and deployment of systems capable of molecular replication can deliver a synthetic machinery that is capable of directing and managing its own synthesis and participate in an organized hierarchy by interacting with other replicating systems. In this way, efficient protocols that allow replication, organization and emergent behaviour can be created within a wholly synthetic chemical context. This approach to predetermined dynamic behaviour has been termed “systems chemistry”. Our lab has developed several molecular systems that are capable of replication by a variety of mechanisms. The ability of these individual replicating systems to function as modules within more complex reaction networks is related to their ability to bind reagents selectively and to accelerate the reactions between them.
