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.
