Research Abstract	One of the striking features of porous coordination polymers is their flexibility inside pores. It is well known that organic molecule shows high mobility when no steric hindrance exists around them, and in PCP, enough space for organic ligand to mobile is available because of its porous nature. In this study, we tried to develop novel dielectric materials controlled by gas adsorption, in which molecular motion accompanied with gas adsorption can be detected as electric signals. It was revealed from the dielectric measurement for several frameworks that the compounds showing structural phase transition synchronized with gas adsorption, i.e., gate-opening, are promising material for dielectric materials controlled by gas adsorption.
