Abstract

A dye-appended β-cyclodextrin (1) associates with α-cyclodextrin (α-CD) with color change, forming an asymmetric rotaxane-like structure containing two different cyclodextrins. The similar phenomenon was observed in the system of 1 and β-CD. The association constant of 1 for α-CD (198 M-1) is larger than that for β-CD (43 M-1), indicating that the pseudo-rotaxane is more stable when 1 associates with α-CD.
