Fine control of specific molecular adsorptivity on a porous coordination polymer by surface modification

针对结晶多孔配位聚合物的独特功能--选择性吸附CO2并伴有结构变化，采用二级有机配体对材料进行改性以精细控制吸附性能。 基于几个分析实验，改性的材料含有相当少量的第二有机配体，然而，它们令人惊讶地在接近室温下吸附烃，而原始材料在相同条件下不能吸附。对具有气体分子的改性材料的评价清楚地表明了通过吸附的材料的结构变化，表明成功地赋予了材料新的功能。

Focused on the unique function of a crystalline porous coordination polymer, which is selective CO2 adsorption accompanied with structural change, modification of the material by secondary organic ligands was performed for fine control of the adsorptivity. Based on the several analytical experiments, the modified materials contain quite small amount of the secondary organic ligands, and however they surprisingly adsorb a hydrocarbon at near room temperature that the pristine material cannot adsorb at the same condition. Evaluation of the modified materials with gas molecules clearly indicated structural change of the materials through the adsorption, indicating a success to give a new function on the materials.
