The first dual component pseudocryptand-type [2]pseudorotaxanes were designed and prepared via the self-assembly of synthetically easily accessible bis(meta-phenylene)-32-crown-10 pyridyl, quinolyl, and naphthyridyl derivatives with paraquat. The formation of the pseudocryptand structures in the complexes remarkably improved the association constant by forming the third pseudobridge via H-bonding with the guest and π-stacking of the heterocyclic units.
首例双组分拟穴居大环型[2]假轮烷通过合成上易于获得的双（间-亚苯基）-32-冠-10 吡啶基、喹啉基和萘啶基衍生物与对铵盐的自组装设计和制备。在配合物中形成拟穴居结构通过与客体形成氢键和杂环单元的π堆积形成第三个拟桥极大地提高了配合物的结合常数。
