Cucurbit[8]uril-mediated phosphorescent supramolecular foldamer for antibiotics sensing in water and cells
文献摘要：
A phosphorescent supramolecular foldamer is conveniently constructed by the 1:1 host-guest complex-ation with cucurbit[8]uril and 1,2-diaminocyclohexane-bridged 4-(4-bromophenyl)-pyridinium salt.The tightly compact host-guest complexation in molecular foldamer can greatly suppress the fluorescence emissive channel and promote the intersystem crossing from singlet to triplet states,thus leading to the green phosphorescence at ambient temperature in aqueous solution.More intriguingly,the phospho-rescence emission shows very rapid and sensitive responsiveness to different antibiotics in both inan-imate milieu and living cells.Remarkably,the limit of detection of such binary inclusion complex to-ward sulfamethazine can reach as low as 1.86×10-7 mol/L.Thus,it is envisaged that this supramolec-ular nanoplatform featuring unique complexation-enhanced phosphorescence emission may hold great promise in sensing and detecting many other biological targets under physiological environment.
