X-ray spectroscopy of multinuclear spin-crossover molecules

The project is embedded in the priority program 2491 of the German Research Foundation (DFG) on interactive switching of spin states and consists of research on di- and trinuclear spin-crossover molecules with the goal to investigate intramolecular coupling and cooperativity in thermal and light-induced spin-switching behavior in bulk materials and adsorbed monolayers. In addition to X-ray absorption spectroscopy, synchrotron-radiation-based THz spectroscopy is being used as a new method for characterization of such materials.
