摘要/Abstract

摘要：

以壳聚糖为母体,合成了携带β-环糊精侧基的壳聚糖大分子主体化合物(CDCS). 通过红外光谱、X-射线衍射和浓硫酸降解等方法对CDCS进行了表征;并利用X-射线衍射和紫外-可见吸收光谱等分析方法研究了CDCS分别与二茂铁和二茂铁苯酮酸的主客体相互作用. 结果表明,带有二茂铁基团的客体与壳聚糖主体化合物侧链上固载的环糊精主体确实发生了主客体相互作用.

Abstract:

The β-CD-grafted-chitosan (CDCS) has been synthesized with chitosan as matrix. The structure of the product has been determined and characterized by FT-IR, XRD, and H₂SO₄ degradation methods. Further more, the host-guest interaction of CDCS with ferrocene and ferrocenylcarbonyl benzoic acid has been systematically studied by employing XRD and UV techniques. As expected, the guest compounds containing ferrocene interact with the β-CD-labeled polymer backbone.

Key words: ferrocene, cyclodextrin, host-guest interanction, chitosan, self-assembly
