From the 4^th-6^th of October the CRC 325 organised the first Conference on Light Induced Transformations (LIT) in Regensburg, Germany. With a broad scientific program, it brought a lot of people from various research fields together to talk and discuss a plethora of scientific problems. The participants met early at the University of Regensburg where the first presentation was given by Takashi Ooi followed by a talk by Christina Wegeberg. After a short coffee break which allowed the discussion of the presented research in a relaxed setting followed talks given by Leyre Marzo, Dieter Sorsche and Santosh Pagire. Alongside the subsequent lunch break participants were encouraged to visit the vernissage organized by art students from the University of Regensburg in cooperation with the CRC to look at stunning art about different perceptions and interpretations of light. Subsequently the last presentations of the day were given by Leticia González, Christoph Kerzig, Simone Stegbauer and Dimitry Katayev. The conference day was closed with a poster session where various members of the CRC as well as participants of the conference were able to present their research topics and talk to numerous interested researchers in different stages of their academic career.

From 16 – 18 August, researchers from the Technical University of Munich working in the Collaborative Research Centre “Assembly Controlled Chemical Photocatalysis” helped organizing and executing the “TUM Entdeckerinnen” event at  TUM. “TUM Entdeckerinnen” meaning TUM Explorers is an event organized by TUM to give girls and young woman the opportunity to follow their scientific interests and gain insights into the fascinating world of chemistry.

On the first day of the event, the girls from 10^th to 12^th grade, arrived at the TUM campus in Garching and after a short get to know, the day started with a lecture on light and colors. During the lecture, some basic photo physical questions were discussed as: “What is light ?”, “How does light disappear ? ”, “How do colors arise ?”. The lecture was loosened up by several show experiments on colors and light, as for example the classic splitting of light through a prism. After the lecture, there was the opportunity for the participants to meet Prof. Cathleen Zeymer during a lunch together. After the lunch, the chemical synthesis planned for the next day was discussed mechanistically and the relevant safety aspects were explained.

From 03 – 05 May, researchers working in the Collaborative Research Center "Assembly Controlled Chemical Photocatalysis" met for the second Graduate-Only-Day at Friedensburg, Kurort Rathen in Saxony. The event provided an opportunity for the members to step out of their regular work environment and engage in activities that promote bonding, team spirit and immersing oneself in different setting to spark creativity and innovation through effective communication and collaboration.

The participants met at the accommodation at Friedensburg guesthouse located approx. 35 km from Dresden in the picturesque climatic health resort of Rathen in the middle of the scenic Saxon Switzerland. After having settled in our rooms, we had a wonderful dinner together which was followed by the first exchange through small team activities in the form of group games.

From 08 – 10 May, 23 researchers working in the Collaborative Research Center "Assembly Controlled Chemical Photocatalysis" met for the first Graduate-Only-Day at Spitzingsee in Bavaria. The event intends to let colleagues get to know each other and their scientific field better, paving the way for new collaborations.

The participants met at the Spitzingsattel by Spitzingsee, and following a short hike reached the accommodation at `Obere Firstalm´, luckily while still dry. After a friendly welcome from the staff, a rich, traditional Bavarian “Raindl” meal awaited us. This was followed by the first exchange through small team activities in the form of group games.
