我们报告了首次使用溶液相卤素键合，通过基于碘三唑轴的溴化物阴离子模板形成轮烷来控制和促进联锁结构的组装。将卤素原子掺入轮烷主体空腔中可显着提高互锁受体的阴离子识别能力，从而在竞争性水介质中提供不寻常的碘化物选择性。
We report the first use of solution-phase halogen bonding to control and facilitate the assembly of an interlocked structure through the bromide anion-templated formation of a rotaxane based upon an iodotriazolium axle. The incorporation of a halogen atom into the rotaxane host cavity dramatically improves the anion-recognition capabilities of the interlocked receptor, giving unusual iodide selectivity in a competitive aqueous medium.
