Porous Scaffolds for Electrochemically Controlled Reversible Capture and Release of Ethylene

This Communication describes the use of porous coordination polymers (PCP) with integrated metal bis­(dithiolene) units to achieve electrochemically controlled capture and release of ethylene in the solid state. Applying positive potential (+2.0 V) to these PCPs promotes ethylene capture, and subsequent dose of negative potential (−2.0 V) induces the release. These materials are resistant to poisoning by small reactive gases (CO and H2S) that may interact with embedded metallic sites.
