However, FA is a known carcinogen and poses significant risks to human health. Therefore, developing a sensitive and selective probe for detecting FA is crucial. Herein, a naphthalimide-based water-soluble fluorescent polymeric probe for selective detection of FA in an aqueous medium at physiological pH is presented. The aromatic hydrazine units present in the side chains of the polymer react with FA through an addition-elimination reaction with the formation of hydrazone derivative, which halts the photoelectron transfer (PET) mechanism within the polymer, leading to a “turn-on” in green fluorescence. The formation of hydrazone is confirmed by electrospray ionization mass spectrometry (ESI-MS) analysis for a model reaction of (6-hydrazinyl-2-(2-hydroxyethyl)-1H-benzo[de]isoquinoline-1,3(2H)-dione, SM) with FA. The sensing mechanism through a PET on–off is supported by density functional theory (DFT) calculation. The probe demonstrates remarkable sensitivity, detecting FA concentrations as low as 1.7 µm, and shows a five-fold fluorescence intensity increase within 10 min when exposed to 10 µm formaldehyde. Additionally, the probe offers selective detection of FA over other analytes via fluorometric methods. This study represents a significant advancement in developing sensitive and selective polymeric probes.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 6","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metal catalysts, especially heavy metal salts, are recognized for their efficiency in degrading this widely used thermoplastic. However, concerns over the non-biodegradable and toxic nature of heavy metal catalysts like Zn and Pb salts, along with their limited selectivity, have led researchers to seek alternative, more environmentally friendly, and cost-effective catalysts. This study explores alternatives such as lithium, sodium, and calcium acetate/formates, demonstrating that selected benign metal salts not only accelerate PET degradation but can also surpass traditional heavy metal acetate catalysts (e.g., Zn acetate) in terms of activity and BHET yield. More importantly, complete PET conversion is achieved within 3 h at ≈188 °C, with excellent BHET yield. The catalytic reactions using lithium and calcium acetate show a superior initial reaction rate under optimized conditions.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 6","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their instability in biological environments and the potential for easy drug release remain major challenges. This study investigates the fabrication of core-crosslinked polymer micelles using photoinduced azide crosslinking to enhance stability and achieve controlled drug release. Amphiphilic copolymers are synthesized using reversible addition-fragmentation chain transfer (RAFT) polymerization, incorporating poly(ethylene glycol) methyl ether (PEG) as the hydrophilic block and a styrene-based azide monomer for the hydrophobic core. The micelles are crosslinked via photoinduced azide crosslinking and characterized for size, morphology, and drug loading capacity (DLC). DOX-loaded micelles demonstrated pH-responsive release, with minimal release at physiological pH (7.4) due to strong π–π stacking interactions between DOX and the hydrophobic core. At acidic pH (5), these interactions weakened, resulting in enhanced drug release, mimicking the conditions of the tumor microenvironment. Core-crosslinked micelles exhibited superior stability, reduced drug leakage, and improved release control compared to non-crosslinked micelles. These results highlight the potential of photo-crosslinked polymer micelles as a robust platform for the delivery of hydrophobic anticancer drugs, addressing key limitations of conventional micelle-based systems.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 7","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, in order to improve the performance of waterborne adhesives, it is important to enhance and control these properties in a refined manner. For this purpose, herein presents a polymeric crosslinker presenting a variable number of methacrylic groups intended to control the degree of crosslinking. Polysuccinimide (PSI), which consists of a series of succinimidyl rings, is conveniently modified with methacrylic functional groups by ring-opening nucleophilic reaction to develop methacrylic PSI (“MA-PSI”). The cohesion and adhesion of MA-PSI crosslinked adhesive is comprehensively controlled by both concentration and degree of methacrylic substitution (DSMA) of MA-PSI. Moreover, the dual crosslinking, accomplished by the successive application of thermal- and photo-crosslinking, further increases the cohesion to the extent that significantly reduces the adhesion strength, which is ideal for debonding applications. Overall, the multimodal MA-PSI is a versatile crosslinker allowing broad controllability of cohesion and adhesion as well as imparting debonding capability.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/macp.202400415","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the different molecular conformation, isotactic polypropylene (IPP) always delivers excellent electrical insulation but poor mechanical toughness, while block polypropylene (BPP) has been dramatically opposed properties. Blending IPP with BPP at an appropriate content may be beneficial to reconcile the toughness and insulation. In this study, the blending ratio of IPP and BPP is first investigated, and it is found that 60: 40 wt.% is the optimized ratio for achieving outstanding overall performance. Furthermore, polyolefin elastomer (POE) and styrene-grafted POE (POE-g-St) are incorporated into IPP/BPP blends respectively to intensify the toughness as well as the insulation property. The microstructure, electrical properties, mechanical properties, and thermal properties of the composites are systematically analyzed and discussed. The results demonstrate that the composite with a grafting ratio of 1.21 wt.% styrene exhibits superior overall performances, the enhanced breakdown field strength of 314.02 kV mm−1, and reduced elastic modulus of 352.54 MPa are achieved. Additionally, the modified composites also possess a high melting temperature, high volume resistivity, and excellent space charge suppression capability, achieving the synergistic improvements of the electrical, mechanical, and thermal properties.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 6","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Crystallization-driven self-assembly (CDSA) has emerged as a powerful and adaptable approach for constructing 2D micellar structures with precise control over dimensions, morphology, and corona chemistry. This technique is particularly significant for creating functional 2D architectures with applications across tissue engineering, nanomedicine, and sensing. Recent advances in CDSA of block copolymers have enabled enhanced structural precision and reproducibility, making it a valuable tool for designing next-generation 2D materials.
