Monitoring molecular nonadiabatic dynamics with femtosecond X-ray diffraction [Chemistry]

26-Jun-2018 | Kochise Bennett; Markus Kowalewski; Jérémy R. Rouxel; Shaul Mukamel, Proceedings of the National Academy of Sciences current issue, 2018

X-ray crystallography has long been used to determine the structure of crystals and molecular samples. More recent advancements in light sources and computational methods made it possible to routinely determine the structure of large proteins. The introduction of X-ray free-electron lasers opens ...

Reversible and Efficient Light-Induced Molecular Switching on an Insulator Surface

18-Jan-2018 | Simon Jaekel; Antje Richter; Robert Lindner; Ralf Bechstein; Christophe Nacci; Stefan Hecht; Angelika Kühnle; Leonha ..., ACS Nano, 2018

Prototypical molecular switches such as azobenzenes exhibit two states, i.e., trans and cis, with different characteristic physical properties. In recent years various derivatives were investigated on metallic surfaces. However, bulk insulators as supporting substrate reveal important advantages ...
