Yippee! Our third paper dealing with the special biipo ligand and an “Unexpected Boost in Activity of a Cu(I) Photosensitizer by Stabilizing a Transient Excited State” is now published in Inorganic Chemistry. This was only possible due to a strong joint cooperation. Many thanks to the groups of Prof. Lochbrunner (Rostock) und Prof. Niedner-Schatteburg (Kaiserslautern). Read more

A big welcome to Kurt Haseloff. Kurt is the newest member of our synthesis group and has just started his bachelor thesis. He will focus on the incorporation of a catechol anchor group into the backbone of different phenanthroline ligands. We wish you a lot of success.

Congratulations to Yingya and Florian! Here is our latest study about the comparison of two different design strategies for improved Cu(I) photosensitizers, i.e. covalent linkage vs. directly fusing of a naphthalimide unit. For further details please have look to our paper in Frontiers in Chemistry: Have a look here

We are pleased about our new joint PhD student. Anastasiia Riabchunova did her Master of Science in Chemistry at the Karazin Kharkiv National University in Ukraine. She joined our group to do her doctoral thesis with us. We hope that you have a good start despite the circumstances.

Our updated master lecture (including a seminar and exciting practical experiments) on photo(redox) catalysis and artificial photosynthesis starts. If you're as excited, sign up and drop by at the Rebenring 31.

There are two great new publications. 1.) Together with research groups from Rostock and Kaiserslautern we provide a full picture of the excited state dynamics of two novel Cu(I) and Ru(II) based Photosensitizers. Read more about this in Inorganic Chemistry. Read more

2.) We are honored to present a new full paper in Chem. Eur. J. about merging of a perylene moiety enables a Ru(II) photosensitizer with long-lived excited atates and the efficient production of singlet oxygen. Have a look here. This publication also includes the front cover and the cover profile. Please, see here.

Welcome to the homepage of the karnahl research group. We are part of the Institute of Physical and Theoretical Chemistry at the Technische Universität Braunschweig. 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.
