Rotaxane-encapsulated cyanine dyes: enhanced fluorescence efficiency and photostability

Chemical Communications Pub Date: 2000-05-09 DOI: 10.1039/B001812K

Abstract

Two isomers of a cyanine dye α-cyclodextrin rotaxane have been synthesised in aqueous solution, and structurally characterised by 2D NMR spectroscopy; they exhibit enhanced fluorescence and photostability, compared with the free dye.
