【摘要】 <正>我们致力于基于冠醚衍生物制备小分子互穿结构和互穿结构连接的超分子聚合物。发现了苯并-21-冠-7可以和二级铵盐形成机械互穿结构而且是可以和它形成机械互穿结构的最小冠醚;揭示了不但可以利用阴离子调节双间苯-32-冠-10/百草枯离子对主客体络合的强弱,而且可以利用阴离子控更多还原

【Abstract】 We are focusing on the fabrication of threaded structures based on crown ether derivatives. There are three main research projects.The first one is the improvement of host-guest complexation for the preparation of large supramolecular systems.For example,we demonstrated that the complexation of paraquat could be improved up to 219 times by the introduction of ion-pair recognition.The second one is the preparation of novel supramolecular polymers based on host-guest complexation.For example,recently we demonstrated that metal-coordination can be used to mediate reversible conversion between linear and crosslinked supramolecular polymers.The third one is the design and preparation of novel host-guest recognition systems.For example,we found that secondary dialkylammonium salts(SDS) are able to thread through the cavity of benzo-21-crown-7(B21C7) to form threaded structures.更多还原
