High-Spin Molecules

Organic high-spin molecules such as polyradicals, polycarbenes, or polynitrenes can be utilized as building blocks for organic magnets. In our laboratory, molecules with six and more unpaired electrons (e. g.trinitrenes) were synthesized and characterized by matrix isolation IR, EPR, and UV-vis spectroscopy. By combining σ- and π-radical centers we synthesize challenging molecules with unusual spin topologies.

Solvent Control of Reactivity

Interactions of reactive intermediates and transition states with solvent molecules determine reactivity and product selectivity, in particular if charge separation is involved. Our group studies solvent interactions of open-shell molecules both by low-temperature and by time-resolved spectroscopy. We could demonstrate that single solvent molecules are able to switch the spin states of carbenes, and thus drastically change their reactivity. This work changed established paradigms on carbene reactivity.

Magnetic Bistability

The coexistence of molecules in different spin states is a largely unexplored phenomenon, contradicting common scientific expectation of rapid intersystem crossing between spin states. Using low-temperature techniques, we isolated carbenes which coexist in their singlet and triplet states. Our work allowed us to establish spin bistability as a general phenomenon, only depending on the singlet-triplet gap of carbenes. This gives us the unique opportunity not only to spectroscopically characterize the same carbene in its different spin states, but also to explore spin-specific reactions in detail.

Tunneling Reactions

Quantum mechanical tunneling (QMT) has been recognized as an important process contributing to chemical reactions. We discovered several reactions where heavier atoms such as carbon undergo QMT, and we study how QMT determines the rates as well as the product selectivities at low temperatures. Examples for tunneling reactions are ring-openings of strained cyclic compounds, insertions of carbenes into the OH bond, activation of dihydrogen, and the Cope rearrangement.

Reactive Intermediates

Much of our research is centered around reactive intermediates which we study using a variety of low-temperature and time-resolved techniques. Besides open-shell molecules, we investigate highly strained and antiaromatic molecules. The focus of our research lies on the reactivity of molecules which are difficult to access experimentally. Reactions include rearrangements, oxidations, hydrogenations, hydrogen- and halogen-bonding, proton and electron transfer, and others.
