Equipment
In our laboratory we synthesize and investigate various organic, organometallic and macromolecular systems. The common procedures for characterization include optical investigations like absorption spectroscopy, luminescence spectroscopy, and time-resolved absorption/fluorescence spectroscopy as well as X-ray diffraction techniques (crystallography, X-ray scattering). Recently, we have developed laboratory based time-resolved X-ray diffraction techniques for characterizing meta-stable structures of materials on the sub-nanometer scale. The ultrafast X-ray diffraction laboratory is set-up at the Center for Free Electron Lasers Science CFEL/ASG in Hamburg.
