Reported herein is the detection of iodine using a non‐covalent association complex formed between a β‐cyclodextrin host and a designer bimane ditriazole guest. This complex responds to the presence of iodine with a marked decrease in the observed fluorescence signal. A sub‐nanomolar detection limit of this system in the solution‐state was determined. Moreover, results using filter paper onto which the β‐cyclodextrin‐bimane complex was adsorbed show a noticeable advantage compared to the cyclodextrin‐free bimane. Thus, highly sensitive on‐paper colorimetric iodine detection was achieved.

β-环糊精：二甲基-二三唑包合物的荧光猝灭检测碘

本文报道了使用β-环糊精宿主与设计者二manman ditriazole来宾之间形成的非共价缔合复合物检测碘的方法。该复合物响应于碘的存在，观察到的荧光信号显着降低。确定了该系统在溶液状态下的亚纳摩尔检测极限。此外，与不含环糊精的二烯相比，使用吸附有β-环糊精-二烯配合物的滤纸的结果显示出明显的优势。因此，实现了高度灵敏的纸上比色碘检测。
