摘要：
(Figure Presented) Chiral hole: The first chiral microporous germanium antimony sulfide with 3D helical channels was constructed by the unprecedented combination of {GeS4} tetrahedra and ψ-{SbS4} trigonal bipyramids. The dimethylammonium cations present in the structure are easily exchanged with alkali metal cations present in aqueous solution. The title compound has high ion-exchange capacity and high selectivity for Cs+ ions. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
