While postpolymerizationmodification (PPM) offers a viable alternative, most strategies relyon designer-activated polymer precursors. Herein, we report a one-potreductive PPM of unactivated poly(dialkylacrylamide)s to access adiverse array of amine-containing functional copolymers. This approachleverages an amide activation strategy using trifluoromethanesulfonicanhydride (Tf2O) to generate electrophilic keteniminiumion intermediates. Subsequent trapping with Grignard reagents and in situ reduction of the resulting iminium species yieldsfunctional tertiary amines that are proximal to the polymer backbone.This approach avoids the need for activated monomers and enables thepreparation of copolymers formally arising from acrylamide and allylamine monomers with tunable physical properties. Importantly, straightforwardquaternization of the newly installed pendant amines furnishes cationicpolymers that exhibit promising antimicrobial activity. This workexpands the scope of unactivated poly(acrylamide) functionalization,providing a robust platform for the discovery of bioactive polymericmaterials.","PeriodicalId":18,"journal":{"name":"ACS Macro Letters","volume":"15 8","pages":"1135–1141"},"PeriodicalIF":4.9,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148655750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In one system, the ELP contains 80 pentapeptide units (C16-80-C16), whereas in the other two C16-ELP40 chains were oxidatively coupled through their terminal cysteine residues to form a central disulfide bond, yielding C16-(40)2-C16. Despite their nearly identical molecular weights and compositions, the two polymers exhibit markedly different self-assembly behaviors. C16-80-C16 forms large hydrophobic aggregates that remain kinetically trapped and do not develop a dynamically connected network. In contrast, C16-(40)2-C16 forms very small associative nodes with an aggregation number of only ∼3 chains. These nodes coexist with larger clusters and become dynamically interconnected at higher concentrations, leading to transparent hydrogels at concentrations as low as 2.5 wt %. Oscillatory rheology reveals a transient Maxwell network governed by a single relaxation process associated with the reversible association of the C16 end groups.

Here, we report a light-responsive poly(ethylene glycol) (PEG) system that enables reversible switching between linear and cyclic topologies, allowing continuous modulation of thermally induced phase transitions. Linear PEG functionalized with styrylpyrene end groups undergoes efficient intramolecular [2 + 2] photocycloaddition under visible light to form cyclic polymers, while UV irradiation restores the linear precursor. This reversible topology interconversion allows continuous tuning of the cyclic/linear ratio. As a result, the cloud point temperature of aqueous solutions can be modulated over a wide range from 37 to 65 °C. Aggregation appears to be enhanced in linear polymers through end-group-mediated π–π stacking and intermicellar bridging, whereas it is suppressed in cyclic polymers due to topological constraints and reduced stacking interactions. This work establishes topology switching as a noninvasive strategy for dynamically regulating polymer solution thermodynamics and highlights topology as a tunable parameter for controlling thermoresponsive behavior.","PeriodicalId":18,"journal":{"name":"ACS Macro Letters","volume":"15 7","pages":"1021–1027"},"PeriodicalIF":4.9,"publicationDate":"2026-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148348874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More importantly, this H-W-E polymerization of triphsophonate 4 with 2,5-hexanedione 6 provided a powerful way to offer 18% flexible moiety in BIT-POP-121 based on low-field NMR. Very high Pd/Pt selectivity of 3.54 and 28 was observed for BIT-POP-121 respectively, based on the adsorption capacity and Kd value using a binary solution of Pd2+ and Pt2+. This is very promising for the Pd recovery from the spent automotive catalytic converters in the future.

Herein, epoxide-cyclic anhydride ring-opening copolymerization produces TEMPO-functional radical polyesters, where strictly alternating enchainment installs a radical at every repeat unit while anhydride comonomer varies spacer structure from flexible aliphatic through alicyclic, bicyclic, and semiaromatic. SQUID magnetometry and EPR spectroscopy confirm radical contents of 86–98%; except for the thioether-containing polyester, where sulfur-specific quenching occurs. Density functional theory calculations reveal that rigid aromatic spacers position radical sites closer than flexible aliphatic ones of comparable through-bond atom counts.

Validated on directed self-assembly (DSA) block copolymer SEM images, the framework effectively overcomes data set limitations, achieving high micro- and macro-averaged F1-scores across rare and complex defect types. Notably, the model attains an F1-score of 0.987 on the critical discrimination between defect-free and defective samples, approaching human-level precision. To confirm the framework’s generalized utility beyond the semiconductor field, we demonstrate its successful transferability to a distinct wood defect data set.
