摘要：

The anionic beta-cyclodextrins, sulfopropylated-beta-cyclodextrin and carboxyethylated-beta-cyclodextrin, have been intercalated into a Zn/Al layered double hydroxide by an ion-exchanging reaction. X-ray diffraction patterns show single-phase hybrids with high crystallinity. Detailed orientations of intercalated anionic beta-cyclodextrins are evaluated by considering the parameters such as the degree of charge compensation between host and guest, the area demand of beta-cyclodextrin molecules, and the interlayer space of the intercalate. Based on the results, we elucidate a model for the arrangement of anionic beta-cyclodextrin molecule in the layered double hydroxide. (C) 2003 Elsevier Ltd. All rights reserved.
