Programmed fluorine binding engineering in anion-pillared metal-organic framework for record trace acetylene capture from ethylene.

ABSTRACT: Porous physisorbents are attractive candidates for selective capture of trace gas or volatile compounds due to their low energy footprints. However, many physisorbents suffer from insufficient sorbate-sorbent interactions, resulting in low uptake or inadequate selectivity when gases are present at trace levels. Here, we report a strategy of programmed fluorine binding engineering in anion-pillared metal-organic frameworks to maximize C₂H₂ binding affinity for benchmark trace C₂H₂ capture from C₂H₄. A robust material (ZJU-300a) was elaborately designed to provide multiple-site fluorine binding model, resulting in an ultrastrong C₂H₂ binding affinity. ZJU-300a exhibits a record-high C₂H_2</
