An impressive location, with a beautiful mountain panorama and lake view, was the place for our 7th seminar day. Many thanks to our guest Prof. Frank Würthner (Universität Würzburg) who gave us insights into "Fundamentals of Dye Assembly" and "Photofunctional Dye Aggregates". Many thanks to our Graduates who presented their work and led to stimulating discussions. An insight into the world of machine learning chemistry was provided by Prof. Julia Westermayr (Universität Leipzig). In addition to the interesting presentations, we were all able to use the time to discuss and advance our research.
