Zeotype Organic-Inorganic Ionic Crystals: Facile Cation Exchange and Controllable Sorption Properties

Size‐selective sorption is exhibited by a zeotype organic–inorganic ionic crystal with 1D channels: the guest‐free phase sorbs water and methanol, while larger molecules are excluded. Moreover, K+ ions, which reside in the channels (see picture; O red, C black, H pink, N blue), can be exchanged with...

Description
Summary:Size‐selective sorption is exhibited by a zeotype organic–inorganic ionic crystal with 1D channels: the guest‐free phase sorbs water and methanol, while larger molecules are excluded. Moreover, K+ ions, which reside in the channels (see picture; O red, C black, H pink, N blue), can be exchanged with other alkali metal ions, and the guest sorption properties depend on the type of alkali metal ions.
