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 H2 S) that may interact with embedded metallic sites.
