摘要:
                                The two isomers of 6-stilbene-amide-alpha-CD (6-StiNH-alpha-CD) exhibit different inclusion behaviors upon complexation with an alkyl chain bearing pyridinium end caps. Photoisomerization of the stilbene moiety of the CD derivative affects threading due to complexation between the axle and trans- or cis-6-StiNH-alpha-CD.
