水杨酸（SA）和聚乙二醇（PEG）/γ-环糊精（CD）-聚拟轮烷的规模加热诱导了一种新型复合物的形成，其中SA居住在由γ-CD/聚拟轮烷柱形成的分子间空间中。通过粉末 X 射线衍射测量和 C-13-固态 NMR 光谱阐明了 SA 并入 PEG/γ-CD-聚拟轮烷结构。新型复合物与PEG/γ-CD-聚拟轮烷之间不同的水蒸气吸附和解吸行为证实了SA分子掺入到复合物的分子间空间中。
Scaled-heating of salicylic acid (SA) and polyethylene glycol (PEG)/gamma-cyclodextrin (CD)-polypseudorotaxane induced a novel complex formation wherein SA was inhabited in the intermolecular spaces formed by the gamma-CD/polypseudorotaxane columns. Incorporation of SA into the PEG/gamma-CD-polypseudorotaxane structure was clarified by powder X-ray diffraction measurements and C-13-solid-state NMR spectroscopy. Different water vapor adsorption and desorption behaviors between the novel complex and PEG/gamma-CD-polypseudorotaxane confirmed the incorporation of SA molecules into the intermolecular spaces in the complex.
