Benzene absorption in a protuberant-grid-type zinc(ii)–organic framework triggered by the migration of guest water molecules

Abstract

The 2D protuberant-grid-type Zn(II)–organic framework consists of unusual racemic interdigitated bilayers and comprises a 3D intersecting channel system. The framework is thermally stable and the channels contain multiple water aggregates. Accompanying the migration of guest water molecules, only the specific channels in the bilayers along the b axis can easily and efficiently absorb guest benzene molecules in a regular manner.
