On July 28, 2023, at the International Conference on Photochemistry (ICP2023) held in Sapporo, Hokkaido, Mr. Magin Benedict Ferrer, a second-year doctoral student from the Laboratory of Photoreactive Molecule Science, received the 'Springer-Nature PPS Poster Award.'
The International Conference on Photochemistry is a comprehensive international symposium that has been addressing photochemistry since 1962. This year's ICP2023 marked its 31st edition. The 'Springer-Nature PPS Poster Award' was established to support the activation of students' research activities, and this time, out of approximately 200 submissions, 12 presenters were selected for their outstanding research achievements in their presentations.

Photochromic molecules are molecular materials that exhibit color changes upon exposure to light, and they have been studied for applications such as radiation detection due to their ability for repeated coloring and erasing. However, conventional materials had low sensitivity and were unsuitable for safety inspection purposes. In this research, the authors successfully achieved high-sensitivity radiation detection and visualization by utilizing an amplification reaction that induces color changes in numerous molecules in response to weak radio-radiation. They established a cycle of coloring with long-wavelength ultraviolet light and erasing with short-wavelength UV light or X-rays. They also combined various innovations, such as utilizing concentrated solutions within molecular capsules, to demonstrate the principles of a highly sensitive radiation sensor materials.

I am happy to receive this award as it's a sign that my research is going in the right direction. The conference was enjoyable, being an opportunity to see the state of photochemical research up close and on a global scale. I would like to thank everyone in the Kawai lab team, as well as Prof. Yanagida and Prof. Yasuhara at NAIST for letting me use the instruments in their lab with a lot of support, and the PPSM laboratory in ENS Paris-Saclay, specifically Dr. Clémence Allain, Dr. Rémi Métivier and Prof. Keitaro Nakatani, for the giving me the opportunity to perform very collaborative research on the Double Degree Program between Univ. Paris-Saclay and NAIST. I would also like to thank the support of the ADI 2021 project funded by the IDEX Paris-Saclay and the IRP Nanosynergetics of which this collaboration is a part.
