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.
我们首次报道了利用溶液相卤素键来控制和促进轮烷的组装，这是通过溴离子模板作用形成的，轮烷的轴基于碘三唑翁。卤素原子的引入极大地提高了轮烷主体空腔的阴离子识别能力，在竞争激烈的水介质中表现出不寻常的碘化选择性。
