Aggregation of amyloid-β peptides (Aβ), a characteristic molecular event of AD, may produce neurotoxic aggregates, notably oligomers that can induce a series of pathogenic change, finally leading to AD. Suppression of Aβ aggregates-induced neurotoxicity via intervention of Aβ aggregation or removal of toxic aggregates are considered as an effective approach for AD treatment. Notably, molecular aggregates formed by assembly of organic molecules have demonstrated promising potential to fight Aβ aggregation due to their advantages, such as high binding affinity, blood-brain barrier permeability, as well as synergistic effect between multiple functionalities, resulting from their unique physicochemical properties in the aggregate state. This review focuses on the recent progress of molecular aggregates for fighting Aβ aggregation in terms of inhibition of Aβ aggregation, redirection of Aβ aggregation into non-toxic aggregates, disassembly of Aβ aggregates, and clearance of Aβ aggregates. Representative examples of the molecular aggregates are categorized by assembly block and manner. Their structural design, working mechanism, and potential of anti-AD are highlighted. Finally, the perspectives and challenges of Aβ aggregation-oriented molecular aggregates for future research are also proposed.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 11","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144220205","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}

The WEP-based composite coating consists of nanohybrid filler prepared by loading silver (Ag) nanoparticles on graphite nanoplatelets (GNP) surface through a facile in situ hydrothermal synthesis and polydopamine (PDA) modification. The PDA modification effectively improves the dispersion and compatibility of GNP/Ag@PDA (GAP) with the WEP matrix. The synergistic effect of Ag with chemical antifouling behavior and GNP with physical barrier function endows the GAP/WEP composite coating with a low corrosion rate of 1.04 × 10−7 mm a−1 after immersing in 3.5 wt.% NaCl solution for 28 days, which is about two orders of magnitude lower than that of blank WEP coating, and a high inhibition rate of 90.81% after immersing in Phaeodactylum tricornutum solution for 7 days.

The upper layer, composed of P(HEMA-co-4VP), swells in acidic environments due to the protonation of pyridine groups, inducing bending toward one side. Conversely, the lower layer, made of P(HEMA-co-AA), expands in alkaline conditions by deprotonation, causing bending toward the opposite direction. The bilayer hydrogel demonstrates significant shape deformations, influenced by variations in layer thickness and pH conditions. Detailed analyses of swelling behaviors, compressive toughness, and rheological properties reveal that the unique composition ensures distinct and tunable mechanical responses. Furthermore, hydrogels fabricated into complex geometries, such as flower- and starfish-shaped structures, showcase practical applications in soft robotics and biomimetic devices. The versatility of the design is further confirmed by substituting P(HEMA-co-4VP) with P(HEMA-co-DMAEMA), which maintained the bidirectional bending responses under both acidic and alkaline conditions. This research expands the theoretical understanding of stimulus-responsive hydrogels and offers an innovative platform for designing intelligent actuators adaptable to diverse and dynamic environments.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905030","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}

To investigate the influence of molecular structures on the dielectric constant and loss factor of TLCPs, 4,4′-dihydroxy diphenyl sulfone (SDP), 4,4′-dihydroxy diphenyl ether (ODP), 4,4′-dihydroxy diphenyl ketone (DHBP), and 4,4′-dihydroxy diphenyl sulfide (TDP) are introduced to copolymerize with 6-hydroxy-2-naphthoic acid (HNA) and terephthalic acid (TA) by one-pot melt polycondensation, which are defined as TLCP-I, TLCP-II, TLCP-III, and TLCP-IV, respectively. All prepared ternary TLCPs exhibit a nematic LC state between 300 and 350 °C, and the crystallinity of the modified TLCPs is reduced to a certain extent by introducing bisphenol moieties compared with the referenced polyarylate (TLCP-0) from 4-hydroxybenzoic acid (HBA) and HNA. Meanwhile, the consequent TLCPs exhibit good thermal stability, and the maximum weight loss rate temperature exceeds 500 °C. Furthermore, the initial storage modulus of TLCP-II, TLCP-III, and TLCP-IV films at room temperature are 1.2, 0.85, and 1.5 GPa, respectively, showing good tensile strength. Most importantly, the dielectric loss factors of TLCP-II, TLCP-III, and TLCP-IV are much less than 0.01 in the range of 1–104 kHz, thus suggesting an ideal low-dielectric-material candidate.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905118","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}

The molecular structure of the flame-retardant PS is characterized via solid state and solution nuclear magnetic resonance spectroscopy, Fourier-transform infrared spectroscopy, and differential scanning calorimetry. Through a comprehensive analysis of results from thermo-gravimetric analysis, thermo-gravimetric Fourier-transform infrared spectroscopy, and elemental analysis, the thermal stability and thermal decomposition mechanisms of PS are investigated.

The results indicated that the as-obtained hydrogel demonstrated excellent freezing resistance due to the combination effects of ion hydration and hydrogen bonds. Moreover, the hydrophobic interactions between protein chains increased with an increase in ethylene glycol concentration.

Tunable and sustainable bio-polyamides (PAs) derived from terpenes offer a promising alternative. This work focuses on limonene polyamide (LiPA) synthesized via anionic ring-opening polymerization (AROP) from limonene lactam and its functionalization via a thiol-ene click reaction. Optimizing the AROP enables the preparation of high molecular weight LiPA up to 54 kg mol−1, rendering the material attractive for further utilization. Subsequent exploration of the side-chain functionalization via thiol-ene click chemistry allows for the introduction of diverse functional groups (e.g., alkyl, ester, sulfonate) and finetuning of the polymers’ properties. The modifications give control over solubility, processability, hydrophilicity, and glass transition temperature (44–133 °C). While alkyl groups increase hydrophobicity, all PAs display hydrophilic surfaces (q < 90°). Notably, the sulfonate-modified LiPA shows amphiphilic behavior, forming micelles in an aqueous solution, demonstrating potential for drug delivery applications. The high tolerance of the thiol-ene reaction towards various functional groups enables future incorporation of bioactive moieties, like cell-binding motifs for tissue engineering. In summary, this investigation demonstrates the tunability of LiPA’s properties through strategic side-chain modifications, paving the way for diverse biomedical applications.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905186","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}

In this study, two non-fused polymerized small molecular acceptors (PSMAs), PFBTz-OD and PFBTz-DT, featuring distinct alkyl side chains are designed and synthesized. Compared with PFBTz-OD, PFBTz-DT exhibits better solubility due to its longer alkyl side chains, resulting in higher molecular weight and favorable temperature-dependent aggregation characteristics in the solution. The all-PSC utilizing PBDB-T:PFBTz-DT attains a power conversion efficiency (PCE) of 9.74%, surpassing the PCE of the PBDB-T:PFBTz-OD device, which stands at 6.60%. The better performance is mainly attributed to the suitable compatibility between the donor and acceptor, which facilitates the formation of optimal phase separation. The proper phase separation, in turn, enhances exciton dissociation, increases the mobility of both electrons and holes and minimizes charge recombination. This study emphasizes how engineering the alkyl side chains influences the control of polymer acceptor aggregation in solution and molecular packing in the film, both of which are essential for optimizing the morphology and improving device performance.","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"226 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905420","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}
