Abstract
A new templating motif for the formation of [2]pseudorotaxanes is described in which rigid, Y-shaped axles with an imidazolium core and aromatic substituents at the 2-, 4- and 5-positions interact with [24]crown-8 ether wheels ([24]crown-8 and dibenzo[24]crown-8). The Y-shape of the axle significantly enhances the association between axle and wheel when compared to simple imidazolium cations.
摘要
描述了一种用于形成[2]准轮烷的新型模板基序，其中具有咪唑鎓核心且在2-、4-和5-位带有芳族取代基的刚性Y形轴与[24]冠-8醚轮（[24]冠-8和二苯并[24]冠-8）相互作用。与简单的咪唑鎓阳离子相比，轴的Y形显著增强了轴与轮之间的缔合。
