�Host-guest� interactions between amphiphilic invertible macromolecules based on PEG and sebacic acid, and potential precursor for electronic materials, cyclohexasilane (Si6H12) in acetonitrile (neither a solvent for cyclohexasilane, nor supporting micellization of amphiphilic invertible macromolecules) and toluene (supporting polymer micellization solvent for cyclohexasilane) have been investigated.In benzene, upon addition of Si6H12 to amphiphilic polymer solution, the 1H NMR study revealed i. interaction between Si6H12 and oxygen-containing functional groups of the polymer and ii. rising additional interaction between cyclohexasilane and hydrophobic polymeric domains formed upon self-assembly.In acetonitrile, despite the extended conformation of the macromolecules and absence of self-assembled polymeric domains, an macromolecular amphiphilicity itself contributes to localizing Si6H12 by AIP and enables Lewis acid-base interaction between Si6H12 and the AIP carbonyl groups. The obtained results demonstrate an interesting phenomenon that insoluble Si6H12 can be localized by AIP macromolecules in a medium which does not support formation of polymeric domains.
