Exploring the influence of chemical modifications on the formation of perylene-based SMPs Maximilian Hagemann and Charl Faul University of Bristol, United Kingdom Supramolecular polymers (SMPs) are an exciting class of materials with a wide range of new properties owing to their dynamic behaviour. A current challenge in the field is to fully control self-assembly behaviour and therefore the properties of the resulting SMPs. The self-assembly behaviour of SMPs can be influenced by a variety of external forces, such as selective chemical modification of the monomers. Hereby, modification of the perylene core (bay, ortho and/or carbonyl positions) are especially interesting, causing not only changes of the stacking behaviour and self-assembly mode of the resulting polymers, but also modifying the optoelectronic properties. 1 Gaining control over those modification can be used as a tool to tune the properties of monomers and SMPs towards their desired application, e.g., for photovoltaic applications. Here we show initial steps towards the synthesis of different perylene SMP monomers with various chemical modifications. Multiple routes of modification are optimised and presented. Following these approaches we are optimistic to obtain novel SMPs, based on chemically modified perylene diimides (PDIs) for further analysis and studies, with control over structure and function.
