Polymer membranes are manifesting the potential in revolutionizing crude oil fractionation for developing energy\u2010efficient, low\u2010footprint petrochemical engineering. Nevertheless, conventional polymer membranes suffer from inferior fractionation performance with unsatisfied permeance and selectivity owing to their polar channel chemistry as well as low\u2010connective and vulnerable channel architecture. We report a kind of robust, fully aromatic fluorinated polyamide (FAFPA) nanofilm that features a switchable molecular gating\u2010on\/gating\u2010off state to activate and reconstruct sub\u2010nanochannels for the permselectivity of hydrocarbon liquids, enabling ultrafast and stable crude oil fractionation. We demonstrate the gating\u2010on state is launched by the interplay of FAFPA networks and polar\u2010matched trigger molecules bearing \u03b1\u2010H such as alcohols and ketones, redefining the sub\u2010nanochannel chemistry and improving the spatial connectivity of sub\u2010nanochannels to accelerate the selective transport of hydrocarbons. The gating\u2010on FAFPA nanofilms show a record\u2010high separation factor of 33 for 1,3,5\u2010triisopropylbenzene with a molecular weight of 204\u00a0Da as well as a profound\n                    <jats:italic>n<\/jats:italic>\n                    \u2010hexane permeance, 24\u2010fold higher than that of the gating\u2010off state. Moreover, these gating\u2010on FAFPA nanofilms can stably handle typical black crude oil at an elevated temperature of 80 \u00b0C for garnering a 32\u2010fold increased permeance while sustaining nearly constant selectivity toward hydrocarbons.\n                  <\/jats:p>","DOI":"10.1002\/anie.202512620","type":"journal-article","created":{"date-parts":[[2025,10,15]],"date-time":"2025-10-15T19:28:24Z","timestamp":1760556504000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Fully Aromatic Fluorinated Polyamide Nanofilms with Molecular Gating for Ultrafast Crude Oil Fractionation"],"prefix":"10.1002","volume":"65","author":[{"given":"Jin\u2010Bo","family":"Li","sequence":"first","affiliation":[{"name":"MOE Key Laboratory of Macromolecular Synthesis and Functionalization, and Key Lab of Adsorption and Separation Materials and Technologies of Zhejiang Province Department of Polymer Science and Engineering Zhejiang University  Hangzhou 310058 China"},{"name":"Department of Chemistry Zhejiang University  Hangzhou 310058 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chang","family":"Liu","sequence":"additional","affiliation":[{"name":"MOE Key Laboratory of Macromolecular Synthesis and Functionalization, and Key Lab of Adsorption and Separation Materials and Technologies of Zhejiang Province Department of Polymer Science and Engineering Zhejiang University  Hangzhou 310058 China"},{"name":"The \u201cBelt and Road\u201d Sino\u2010Portugal Joint Lab on Advanced Materials, International Research Center for X Polymers Zhejiang University  Hangzhou 310058 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheng\u2010Ye","family":"Zhu","sequence":"additional","affiliation":[{"name":"MOE Key Laboratory of Macromolecular Synthesis and Functionalization, and Key Lab of Adsorption and Separation Materials and Technologies of Zhejiang Province Department of Polymer Science and Engineering Zhejiang University  Hangzhou 310058 China"},{"name":"The \u201cBelt and Road\u201d Sino\u2010Portugal Joint Lab on Advanced Materials, International Research Center for X Polymers Zhejiang University  Hangzhou 310058 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia\u2010Hui","family":"Xin","sequence":"additional","affiliation":[{"name":"MOE Key Laboratory of Macromolecular Synthesis and Functionalization, and Key Lab of Adsorption and Separation Materials and Technologies of Zhejiang Province Department of Polymer Science and Engineering Zhejiang University  Hangzhou 310058 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhi","family":"Wang","sequence":"additional","affiliation":[{"name":"Scientific Research and Technology Department Sinopec Qilu Company Ltd.
