ABSTRACT

A novel 1:1 supramolecular dye inclusion complex between inverted cucurbit[7]uril (iQ[7]) and Thioflavin T (THT) has been successfully constructed on the basis of host–guest recognition. The obtained results revealed that THT exhibited obvious iQ[7]-induced fluorescence enhancement in this inclusion complex system, and the N-dimethyl and benzene ring moiety of the guest THT were located inside the cavity of iQ[7], whereas the other section of THT remained outside the portal. And THT@iQ[7] was highly stimuli-responsive to competing guests. These results provided a possibility for application in the molecular recognition area.

倒葫芦[7]脲与硫黄素T自组装构建的刺激响应性超分子染料包合物

摘要

在主客体识别的基础上，成功构建了倒葫芦[7]脲（iQ[7]）和硫黄素T（THT）之间的新型1:1超分子染料包合物。结果表明，THT在该包合物体系中表现出明显的iQ[7]诱导的荧光增强，客体THT的N-二甲基和苯环部分位于iQ[7]的空腔内，而另一部分位于iQ[7]的空腔内。的 THT 留在门户之外。并且 THT@iQ[7] 对竞争的客人具有高度的刺激反应。这些结果为分子识别领域的应用提供了可能。
