Abstract 6-O-α-d-Glucopyranosyl α-cyclodextrin - para-nitrophenol host–guest inclusion complex has been characterized by high resolution 1H-NMR. Analysis on the NMR spectral parameters of the anomeric proton resonances of the host molecule has revealed that the asymmetric nature of 6-O-α-d-Glucopyranosyl α-cyclodextrin molecule is further enhanced by the complexation with para-nitrophenol, indicating an induced-fit type conformational change induced on the host upon the complexation.
