Structural dynamics of soft crystals filmed by table-top ultrafast electron diffraction

Keywords
Time-resolved Electron Diffraction, Soft Crystal, Femtosecond Laser, Structural Dynamics

Research Outline

Ultrafast time-resolved electron diffraction is the methodology to directly observe the structural dynamics of molecules on the femtosecond (10–15 seconds) to picosecond (10–12 seconds) timescale. The researcher has developed the ultrafast time-resolved electron diffraction setup, and will observe and understand the structural dynamics of stimuli-driven phenomena of organic crystals and liquid crystals (stimuli-responsive soft crystals), such as photo-response, thermal-response, vapor-response, or mechanical response, using the relevant setup. Especially, the researcher will focus on the structural dynamics of ill-defined molecular assembles which are difficult to be analyzed with other methodologies. The obtained results lead to the creation of new stimuli-responsive molecular assembles.
