Our research focuses on the organoelement chemistry of the p-block elements in particular. Based on fundamental molecular features derived from specific bonding situations, unique properties such as σ- and π-conjugation can be achieved. In this respect controlling the stereochemistry of stereogenic group 15 centers is part of our investigations, be it for fundamental questions of chirality or the stereochemical alignment of multiple stereogenic centers. In our research we are aiming at the assembly of molecular materials with a special focus on smart inorganic polymers as part of a European research initiative (SIPs).
