Abstract: Microporous Polymer Networks are an emerging new class of functional materials, which combine several advantages of conventional porous matter, like zeolites, activated charcoals or metal organic frameworks. Due to a contorted but rigid structure these polymers exhibit exceptionally high porosities and surface areas in the dry state, while their covalent organic nature ensures lightweight and high thermal and chemical stability. As solely composed of organic compounds an exquisite control over the chemical nature of the large accessible surface areas as well as the physical properties of the resulting networks is possible.[1] All these properties make microporous polymers interesting for a number of applications, especially for gas storage and separation, but recently also their great potential in energy applications[2] or for organic electronics[3] has been shown. Finally, microporous polymers open new prospects in the field of catalysis, as various organic functionalities can be introduced as maintaining parts of the polymer backbones. As main topic, the immobilization of catalytically active species into porous networks will be presented, showing the potential of microporous polymers for diverse catalytic applications from the activation of small molecules like methane or CO2[4] to photocatalysis[5] to asymmetric organocatalysis.[6] Furthermore functional organic networks with weakly coordinating anions and cations will be presented, which show interesting properties for a variety of applications.[7]

Biography: Johannes Schmidt completed a PhD with Professor Markus Antonietti at the Max-Planck-Institute of Colloids and Interfaces in 2010. He then held a postdoctoral fellowship and was promoted as a Research Scienctist at the Technical University of Berlin in Germany. His research focus is the synthesis of functional microporous polymer networks and their sustainable applciations.
