October, 2021

Together with Yann Pellegrin, Axel Klein and Jérôme Fortage I am serving as guest editor for the special issue "Oxidative and Reductive Quenching of Excited States: Enlightening the Way in Photochemistry" in Frontiers in Chemistry. Contributions are welcome. Please, have a look.

July, 2021

Our new lecture series on "photo(redox) catalysis and artificial photosynthesis" came to a successful end.

July, 2021

Our new baby, an emission spectrometer (Fluoromax Plus) from Horiba Jobin Yvon has been delivered and is now ready for use up to 1500 nm.

March/April, 2021

The group moves to the Technische Universität Braunschweig. From April 1st we are part of the Department of Energy Conversion at the Institute of Physical and Theoretical Chemistry. We are looking forward to an interesting future with new colleagues and cooperation partners. Our new laboratories are located at the Rebenring 31, in 38106 Braunschweig.

March, 2021

There are two more publications:
1.) The master thesis of Florian about cross-coupled phenyl- and alkynyl-based phenanthrolines and their Cu(I) photosensitizers was published in Inorganic Chemistry. Good job! Read more

2.) The new paper by Robin and co-workers in ChemPhotoChem demonstrates the application of Cu(I) photosensitizers for the photocatalytic CO2 reduction. Many thanks also to Dr. Schwalbe and Prof. Tschierlei! Read more

Welcome to the homepage of the karnahl research group. We are part of the Institute of Organic Chemistry at the University of Stuttgart. The homepage provides an overview about our current research interests, recent publications and open positions. For further details please check the different pages and enjoy reading.
