Cooperative Polymerization Catalysis

The development of polymerization catalysts is not only a merit in itself, but ideally provides materials with novel properties. In this regard, we try to implement N-heterocyclic olefins (NHOs) as organocatalysts for the synthesis of polymer architectures which allow for creating a tunable, porous platform material. We have recently demonstrated the first NHO-mediated organopolymerizations. On this basis, it is possible to use a solvent- and metal-free polymerization process for the preparation of very well-defined amphiphilic polyethers. These in turn can be converted into micro- or mesoporous carbon materials. We aim at preparing these carbon materials with predictable pore sizes, all depending on the properties of the underlying polyether structures. If successful, this will allow for creating tailor-made materials for electrodes or catalytic supports. Characterization, application and development of battery/supercapacitator devices as well as catalytic experiments using these materials are part of our investigations.
