以丁二炔-苯环冠醚作为大环化合物,以带有4,4’-联吡啶正离子结构的线性分子作为半封端分子,通过简便的一锅法合成一种新的[2]轮烷分子,产率为24%.经高分辨质谱、核磁共振氢谱、核磁共振碳谱等手段确认了丁二炔-苯环冠醚大环与带有两个4,4’-联吡啶二正离子的线性封端分子组装形成[2]轮烷结构,且丁二炔-苯环冠醚在线性分子的两个识别点间作往返运动.
With diacetylene-benzene ring crown ether as the macrocyclic compound, linear molecules with 4,4’-dipyridyl cation as the semi-endcapping molecule, a simple one-pot synthesis of a new [2] Rotaxane molecule, the yield was 24% .High-resolution mass spectrometry, 1H nuclear magnetic resonance spectroscopy, nuclear magnetic resonance spectroscopy and other means to confirm the diacetylene - benzene ring crown ether ring and with two 4,4’-bipyridine The linear capping molecules of di-positive ions assemble to form [2] rotaxane structure, and diacetylene-benzene ring crown ether reciprocates between two recognition points of linear molecules.
