Porous Coordination‐Polymer Crystals with Gated Channels Specific for Supercritical Gases

Abstract

Flexible and dynamic coordination polymers based on interpenetration and interdigitation have been synthesized and characterized. Reversible crystal-to-crystal transformation from a nonporous structure (24 m2 g−1) to a microporous structure (at least 320 m2 g−1) is triggered by adsorption of various supercritical gases (see picture).
