Abstract: Novel cyclodextrin dimer capsules where two heptakis(6- O - tert -butyldimethylsilyl)-β-cyclodextrin (TBDMS-β-CD) molecules are covalently connected with seven xylylene linkers are easily synthesized by a reaction of TBDMS-β-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.
