We develop sustainable catalytic transformations as well as new catalytic concepts and strategies for selective functional group interconversions and and cross-coupling reactions with a strong focus on visible-light photocatalysis. We are particularly interested in heterogeneous photocatalysis for organic synthesis using organic and inorganic semiconductors. These materials are promising sustainable alternatives to common homogeneous photocatalysts given their straightforward recycling strategies (e.g. filtration), high stability, and ease of preparation.
Many parameters influence the selectivity of a chemical reaction, such as varying the catalyst/coordinated ligands, directing groups or by tuning external parameters. Although is known, that the selectivity of photochemical reactions varies with different wavelengths, examples that use this for visible-light photocatalysis are rare. We develop and investigate photocatalytic systems in which the choice of the wavelenght can be used as a parameter to control the outcome of the reaction.
