Abstract

Abstract: Novel cyclodextrin dimer capsules where two heptakis(6-O-tert-butyldimethylsilyl)-beta-cyclodextrin (TBDMS-beta-CD) molecules are covalently connected with seven xylylene linkers are easily synthesized by a reaction of TBDMS-beta-CD with m- or p-xylylene dibromide in 1,4-dioxane. These dimer capsules show inclusion selectivity for phenol and aniline over benzene and toluene in cyclohexane-d(12), and the guest inclusion ability of the capsule is affected by the type of linker connecting two CD rings.
