Research Outline

Novel functional-materials, “Soft crystals,” produces a phase transition or luminescence-property change by weak external-fields, which are photo irradiation, vapor exposure, mechanical pushing, and others. We explore a time-resolved structural-change in an atomic level or electronic state during phase transition in soft crystals using ‘X-ray molecular movie’ to understand mechanisms of the functions. A pump-probe experiment is executed with LASER pumping to generate intermediate states of photo excitation, pressure impress, thermal jump, and so on. X-ray free electron laser (XFEL) and pulsed synchrotron-radiation are used for a probing in a range of time scale from femtosecond to minute. We advance an appropriate system for each soft crystal, i.e., multi-probing which are X-ray crystallography, X-ray absorption spectroscopy, X-ray scattering and photoelectron microscopy.
