Herein, we design chiral membranes via stereoregular self-assembly of recyclable polymers for enantioselective nanofiltration. By incorporating two inherent stereogenic centers into the repeating unit, we created well-defined chiral recognition sites for amino acids. As a result of stereoregular self-assembly, the polymer adopted more extended conformations with larger radii of gyration, denser packing, and higher crystallinity, leading to superior thermal, mechanical, and chemical stabilities. The dual stereogenic centers enable tailoring both enantioselectivity and nanofiltration performance. We unveil the relation between enantioselectivity and enantiomer rejection, and reveal the effects of applied pressure on the enantioselectivity in both permeate and retentate, highlighting the pressure-dependent separation behavior. The design of stereoregular self-assembled membranes offers intrinsically ordered architectures, refined molecular selectivity, and precise structural control without complex processing, establishing a new design strategy for sustainable, high-performance separation systems.","PeriodicalId":388,"journal":{"name":"Matter","volume":"24 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147726573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, room-temperature solution processes typically yield insufficiently protective shells, whereas conventional high-temperature sintering enables densified encapsulation but often damages thermally sensitive NCs and causes irreversible MSN agglomeration. Here, we resolve this conflict through a mesopore-selective sintering strategy for low-temperature densified encapsulation. By pre-installing ultralow, framework-anchored K (0.5–1.0 atom %) in mesopore walls, we achieve local bond activation: atomically dispersed K coordinated to Si–O–Si bridges locally polarizes the silica network and lowers the Si–O bond dissociation energy from 2.54 to 1.38 eV. This programmed bond weakening triggers mesopore-selective collapse at markedly reduced temperatures, yielding densified, ceramic-like shells without bulk fluxing or sacrificing solution processability. This strategy successfully encapsulates CsPbBr<sub>3</sub> NCs at 400°C, alongside temperature-sensitive InP/ZnSe NCs and K<sub>2</sub>SiF<sub>6</sub>:Mn<sup>4+</sup> phosphor, yielding solution-processable fluorescent nanospheres with ceramic-level stability for biological or micro-LED applications.","PeriodicalId":388,"journal":{"name":"Matter","volume":"9 1","pages":""},"PeriodicalIF":18.9,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147709116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
