Outline of Final Research Achievements

This study revealed the structural change in the gas adsorption of porous coordination polymers (PCPs) with selective sorption property by the synchrotron powder diffraction method. It was found that a certain interdigitate type PCP has an unusual framework structure in CO2 adsorbed phase. Interdigitate type PCPs usually have framework structure in which the ligand molecules stack by π-π interaction. But in this compound, another pore is formed between the ligand molecules and the amount of adsorbate CO2 increased. The relation between the characteristic flexible framework and selective sorption property of PCPs was revealed.
