Outline of Final Research Achievements

The objective of the research is to observe time resolved diffraction using the Sakura X-ray Free Electron Laser (XFEL) at Spring-8. XFEL is an intense pulsed X-ray laser which is capable of time-resolved diffraction. We wanted to utilize the XFEL to study the time evolution of gate opening behaviour in porous coordination polymers(PCPs). PCPs are a unique class of crystalline solids which are capable of gas adsorption, separations along with structural deformation. By utilizing one laser pulse X-ray diffraction and along with a gas dosing apparatus, we have managed to visualize breathing behaviour of Copper Kagome PCP in CO gas. Our research results will impact the area of gas separation and storage.
