N,N'-双二茂铁亚甲基丁二胺季铵盐和侧链携带β-环糊精的聚丙烯酰胺的合成及相互间的主客体包结作用

合成了双客体化合物N,N'-双二茂铁亚甲基丁二胺的季铵盐(1)和侧链携带β-环糊精(β-CD)的聚丙烯酰胺(3), 利用FTIR, ¹H NMR, 元素分析等手段表征了合成化合物. 在此基础上以¹H NMR、循环伏安、X射线粉末衍射以及扫描电镜等手段研究了化合物1与3间的主客体包结作用. 结果表明, 处于1两端的二茂铁基均可被位于3侧链的β-CD包结, 引起高分子化合物3分子内和分子间的物理交联, 形成超分子三维网络结构.

Studies on the Host-Gust Interaction between Quaternary Ammo-nium Salt of N,N'-Bis(ferrocenylmethylene)diaminobutane and β-Cyclodextrin Modified Poly(acrylamide)

The quaternary ammonium salt of N,N′-bis(ferrocenylmethylene)diaminobutane and β-cyclodextrin labeled polyacrylamide have been prepared in this work. The composition and structures of the products have been determined and characterized by FTIR, ¹H NMR and elemental analysis. Furthermore, the host-guest interaction between the bi-guest molecule and β-cyclodextrin labeled polyacrylamide has been systematically studied by employing ¹H NMR, cyclovoltammetry, X-ray diffractometry, scanning electron microscopy techniques, etc. As that expected, the two ferrocene groups attached to the ends of the linker can act as guest to β-CD labeled on the backbone simultaneously, and form supermolecular 3-dimensional networks.
