Here an innovative covalent organic network (CON) membrane featuring 3D interpenetrated ultra\u2010microporous channels for effective fractionation of small\u2010molecule solutes is presented. Rational utilization of unique tetrahedral amine (TAM) as aqueous\u2010phase building blocks to crosslink with acyl chlorides yields CON polyamide thin films with finely tuned ordered porosity. Importantly, three\u2010node acyl chloride (TMC) with high reactivity facilitates sharpening the membrane pore size distribution due to the partially ordered and elevated crosslinked structure. Molecular dynamics simulations reveal that these TAM\u2010TMC membranes possess a high fractional free volume, contributing to superior permeability\u2010selectivity performance. Further post\u2010activation with polar solvents effectively modulates the inherent pore polarity and width, resulting in an exceptional methanol permeability of 7.5 L m\n                    <jats:sup>\u22122<\/jats:sup>\n                    h\n                    <jats:sup>\u22121<\/jats:sup>\n                    bar\n                    <jats:sup>\u22121<\/jats:sup>\n                    and a molecular weight cut\u2010off of 248\u00a0Da. This ultrafine 3D hierarchical pore architecture enables excellent fractionation of dye mixtures with similar molecular weights and efficient antibiotic concentration. This work rationalizes the design of chemically stable covalent organic network membranes with 3D partially ordered sub\u2010microporosity, extending their application to precision molecular separations.\n                  <\/jats:p>","DOI":"10.1002\/advs.202510911","type":"journal-article","created":{"date-parts":[[2025,8,4]],"date-time":"2025-08-04T09:06:07Z","timestamp":1754298367000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["3D Covalent Organic Network Membranes With Regionally Ordered Nanochannels for Efficient Molecular Sieving"],"prefix":"10.1002","volume":"12","author":[{"given":"Lei","family":"Ge","sequence":"first","affiliation":[{"name":"School of Chemical Engineering Zhengzhou University  Zhengzhou 450001 PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gaojing","family":"Du","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering Zhengzhou University  Zhengzhou 450001 PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hengjie","family":"Song","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering Zhengzhou University  Zhengzhou 450001 PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiaqi","family":"Li","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering Zhengzhou University  Zhengzhou 450001 PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingwei","family":"Hou","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering The University of Queensland  St Lucia QLD 4072 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yatao","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering Zhengzhou University  Zhengzhou 450001 PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1200-715X","authenticated-orcid":false,"given":"Junyong","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering Zhengzhou University  Zhengzhou 450001 PR China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,8,4]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"crossref","DOI":"10.1126\/sciadv.ado4332","volume":"10","author":"Fan H.","journal-title":"Sci.
