Researchers uncover how the halogen bond can be exploited to direct sequential dynamics in the multi-functional crystals, offering crucial insights for developing ultrafast-response times for multilevel optical storage.

Halogen bonds are intermolecular interactions that arise from the attraction between a halogen atom and another atom with lone pairs, more generally a molecular entity with high electron density. Understanding the distinctive and highly directional nature of halogen bonds is crucial for crystal engineering and studying photoinduced structural deformations, which is key for the development of innovative photo-functional materials.

To solve this problem, a team of researchers, led by Assistant Professor Tadahiko Ishikawa from the Department of Chemistry at the School of Science at Tokyo Institute of Technology , Associate Professor Kazuyuki Takahashi affiliated with Kobe University, Dr. Yifeng Jiang affiliated with the European X-Ray Free-Electron Laser Facility , and Professor R. J.

The future development of functional magnetic devices based on ultrafast optical manipulation of spins requires an understanding of the depth-dependent spin dynamics across the interfaces of complex ...
