Abstract

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. Graphical Abstract

反向葫芦[7]与硫黄素自组装构建的刺激响应超分子染料包合物

在主客体识别的基础上，成功构建了一种新型的倒置葫芦[7]乌尔(iQ[7])与硫黄素T (THT)之间的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诱导的荧光增强[7]，并且客体THT的n -二甲基和苯环部分位于iQ的空腔内[7]，而THT的其他部分则位于门洞外。而THT@iQ[7]对竞争的客人表现出高度的刺激反应。这些结果为分子识别领域的应用提供了可能。图形抽象

期刊介绍： Supramolecular Chemistry welcomes manuscripts from the fields and sub-disciplines related to supramolecular chemistry and non-covalent interactions. From host-guest chemistry, self-assembly and systems chemistry, through materials chemistry and biochemical systems, we interpret supramolecular chemistry in the broadest possible sense. Interdisciplinary manuscripts are particularly encouraged. Manuscript types include: high priority communications; full papers; reviews, and; Methods papers, techniques tutorials highlighting procedures and technologies that are important to the field. We aim to publish papers in a timely fashion and as soon as a paper has been accepted and typeset it will be published in electronic form on the Latest articles section of the website. The two most important review criteria are that the paper presents high-quality work that fits generally into the broad spectrum of activities in the supramolecular chemistry field. Under normal circumstances, Supramolecular Chemistry does not consider manuscripts that would be more suitable in a highly specialized journal. This includes, but is not limited to, those based mostly or exclusively on topics such as solid state/X-ray structures, computational chemistry, or electrochemistry. . The two most important review criteria are that the paper presents high-quality work that fits generally into the broad spectrum of activities in the supramolecular chemistry field.
