摘要：A novel [1]rotaxane 2 has been synthesized employing a 4-methyl-benzenesulfonyl and an azobenzene modified beta-cyclodextrin (beta-CyD) at the 2 position, through self-inclusion complexation and Suzuki-coupling capping in aqueous solution. Disparate absorption, induced circular dichroism (ICD) properties from its isomer [I]rotaxane 1, prepared from the isomeric beta-CyD modifier at the 6 position, and the photoisomerization of [I]rotaxane 2 were thoroughly investigated.
