Guest-Induced Asymmetry in a Metal−Organic Porous Solid with Reversible Single-Crystal-to-Single-Crystal Structural Transformation

Abstract

A metal-organic honeycomb-like 2D pillared-bilayer open framework has been constructed which shows dynamic sponge-like single-crystal-to-single-crystal transformation upon dehydration and rehydration. The dehydrated acentric nonporous phase transformed to the porous centric phase with the selective adsorbate concomitant with the structural transformation correlated with the single-crystal structure determination.
