Outline of Final Research Achievements

The aim of this study is development of in situ and high-resolution powder diffraction measurement system under gas pressure control to clarify the gas adsorption / desorption process of the porous coordination polymers with extremely high gas adsorption capacity and selective gas adsorption ability. The in-situ powder diffraction measurement system with excellent temporal (msec) and angle resolution under gas pressure control was developed at BL02B2 beamline of synchrotron radiation facility (SPring-8). Some porous coordination polymers were tested by using developed instruments, it was found to observe the intermediate phase which was not observed so far, and it was successfully to observe small structural change before and after gas adsorption.
