A triptycene-derived macrotricyclic host containing two dibenzo-[30]-crown-10 moieties forms stable 1:2 host-guest complexes with paraquat derivatives in both solution and the solid state, in which anion-π interactions between PF(6)(-) and the bipyridinium rings play an important role. Moreover, it was found that binding and release of the guest molecules in the complexes could be easily controlled by the addition and removal of potassium ions.
一种基于三联苯的大环主体，其中包含两个二苯并[30]冠-10 部分，在溶液和固态中均与对醌衍生物形成稳定的 1:2 主客体配合物，其中 PF(6)(-)与双吡啶环之间的阴离子-π 相互作用起着重要作用。此外，还发现配合物中客体分子的结合和释放可以通过添加和去除钾离子来轻松控制。
