The understanding of structure-property relations is the key to create function on the molecular level. We combine concepts and tools of physical organic chemistry to address this challenge.
In this context we explore the unique opportunities to substitute carbon-carbon bounds with boron-nitrogen moieties in catalysis as well as new π-materials. Alternatively, we investigate new concepts to control properties of π-nanocarbons such as cycloparaphenylenes (CPPs) via synthesis in solution, via flow chemistry, as well as by on-surface-synthesis.
Additionally, we use dynamic strategies, namely molecular switches based on the azobenzene scaffold as molecular tool to address fundamental questions. These include London dispersion interactions, smart supramolecular assemblies for instance in macrocyclic arrangements.
In general we place our fundamental research in the context of energy-related questions, such as organic flow batteries, molecular solar thermal storage systems (MOST), metal-free hydrogen storage, or novel electronic organic materials.

The Publication originated from an interdisciplinary collaboration of the Art & Chemistry departements of the JLU. The concept of the central perspective is transfered to chemistry to develop new graphical representations for molecules and atoms. The project was supported by the Schering Stiftung.
The two publications with the titles: "Long-lived azafullerenyl radical stabilized by supramolecular shielding with a cycloparaphenylene" and "Exploring London dispersion and solvent interactions at alkyl-alkyl interfaces using azobenzene switches" are now available online as accepted article in Angew. Chem. Int. Ed..
Sebastian Ahles obtained his doctoral degree today. For his Thesis, he mainly worked on new Applications of the Inverse Electron Demand Diels-Alder (IEDDA) reaction and successfully merged it with a photochemical approach.
Hermann Wegner has been appointed as a member of the committee on "Kinetics and reaction mechanisms" of the DECHEMA.
In the publikation with the title "Combining Bidentate Lewis Acid Catalysis and Photochemistry: Formal Insertion of o-Xylene into an Enamine Double Bond" a new reaction pathway for o-quinodimethane derivatives upon irradiation with blue LEDs is presented.
