Bioinspired recognition in metal-organic frameworks enabling precise sieving separation of fluorinated propylene and propane mixtures.

ABSTRACT: The separation of fluorinated propane/propylene mixtures remains a major challenge in the electronics industry. Inspired by biological ion channels with negatively charged inner walls that allow selective transport of cations, we presented a series of formic acid-based metal-organic frameworks (MFA) featuring biomimetic multi-hydrogen confined cavities. These MFA materials, especially the cobalt formate (CoFA), exhibit specific recognition of hexafluoropropylene (C₃F₆) while facilitating size exclusion of perfluoropropane (C₃F₈). The dual-functional adsorbent offers multiple binding sites to realize intelligent selective recognition of C₃F₆, as supported by theoretical calculations and in situ spectroscopic experiments. Mixe
