The integration of innovative concepts and principles of supramolecular chemistry, particularly unorthodox or "exotic" interactions, is a unifying theme in the group, covering different functions. In this spirit, fundamental studies without direct relevance for function can occur as well. Examples include the introduction of ionpair-π interactions or the third orthogonal dynamic covalent bond.
Much current emphasis on anion-π interactions, chalcogen bonds and pnictogen bonds in catalysis is highlighted separately. These topics emerged from the use of the same interactions to transport ions across lipid bilayer membranes (rigid-rod molecules, artificial beta barrels, slides, stacks, voltage gating, ligand gating). This original interest in transport across membranes has also lead to extended periods of research on artificial photosystems (surface architectures, SOSIP, OMARG, surface-initiated ring-opening disulfide exchange polymerization, self-sorting, zipper assembly), and on sensors (biosensors, differential sensing, aptamer-immunosensing, artificial tongue, artificial nose). Experience from these topics reemerge here and there in ongoing research, sometimes on special request by group members or collaborators.
