A bistable [2]rotaxane containing a halogen bonding benzimidazole-iodotriazole station directly conjugated to a naphthalimide station axle component is demonstrated to undergo macrocycle shuttling translocation only upon both protonation and chloride anion recognition. A naked-eye detectable colour response results from the co-conformational change of the host structure.
一种双稳态[2]轮烷被证明,其包含一个与萘酰亚胺轴组分直接共轭的卤键联苯并咪唑-碘三唑位点,只有在质子化和氯离子识别同时发生时才会发生大环穿梭易位。主体结构的共构象变化导致了肉眼可检测的颜色响应。
