Host-guest interactions between a nonmicellized amphiphilic invertible polymer and insoluble cyclohexasilane in acetonitrile

摘要

Host-guest interactions between cyclohexasilane (Si_6H _(12)) and amphiphilic invertible macromolecules based on PEG and sebacic acid in acetonitrile (neither a solvent for cyclohexasilane nor a support for the micellization of amphiphilic invertible macromolecules) have been investigated. Despite the extended conformation of the macromolecules and the absence of self-assembled polymeric domains, a macromolecular amphiphilicity itself contributes to localizing Si_6H_(12) by AIP and thus enables Lewis acid-base interactions between Si_6H_(12) and the AIP carbonyl groups. The obtained results demonstrate an interesting phenomenon in that insoluble Si_6H_(12) can be localized by AIP macromolecules in a medium that does not support the formation of polymeric domains.
