Abstract

Highly conductive, crystalline, polymer electrolytes, β-cyclodextrin (β-CD)-polyethylene oxide (PEO)/LiAsF₆ and β-CD-PEO/NaAsF₆, were prepared through supramolecular self-assembly of PEO, β-CD, and LiAsF₆/NaAsF₆. The assembled β-CDs form nanochannels in which the PEO/X⁺ (X=Li, Na) complexes are confined. The nanochannels provide a pathway for directional motion of the alkali metal ions and, at the same time, separate the cations and the anions by size exclusion. Highly conductive, crystalline, polymer electrolytes, β-cyclodextrin (β-CD)-polyethylene oxide (PEO)/LiAsF₆ and β-CD-PEO/NaAsF₆, consist of the nanochannels formed by the self-assembly of β-CD and PEO. The nanochannels provide the pathway for the directional motion of the alkali metal ions and, at the same time separate the alkali metal ions and the anions by size exclusion (see figure).
