To replicate these properties in synthetic systems, chemists have developed sequence-defined macromolecules-polymers with absolute control over monomer sequence and structure, enabling tailored functions. However, their exploration in material science remains limited due to the challenges of synthesis, which is often low-yielding and time-consuming. To address this, we designed and synthesized Fmoc-assisted stereo-controlled sequence-defined oligourethanes (SDOUs) in the solution phase. Our step-economical synthesis employs a two-step, one-pot strategy, eliminating intermediate purification and achieving an average yield of >85% per step. The optimized protocol, using six modified chiral monomers, enables precise stereochemical and sequence control. Thermal analysis revealed that stereochemistry significantly influences thermal transitions, including glass transition, crystallization, and melting behaviors. Tandem mass spectrometry provided in-depth sequencing analysis. We also demonstrated the post-synthetic modification of the SDOUs with dansyl chloride and explored their photophysical properties, such as solvatochromism and aggregation. Circular dichroism analysis highlighted their unique structural and conformational features. This approach establishes scalable, efficient synthetic routes for stereochemically controlled sequence-defined oligourethanes with diverse functional groups.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e00378"},"PeriodicalIF":4.2,"publicationDate":"2025-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144367711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional polymers, for instance, degrade in acidic environments as chemical bond cleavage leads to significant loss of stiffness and strength. In contrast, acid-resistant bacteria such as Escherichia coli and Lactococcus lactis neutralize protons and undergo biochemical adaptations to withstand acidity.Objective: Inspired by natural acid adaptation, we develop an acid-adaptive polymer with exceptional acid resistance and a unique acid-triggered mechanical restoration behavior.Methods: By incorporating sodium carboxylate and amino functional groups, the polymer effectively neutralizes protons, mitigating acid-induced degradation. Besides, invading acids facilitate amidation reactions at temperatures as low as 40°C, forming secondary crosslinks within the polymer matrix.Results: This process enhances the material's stiffness and strength by 119% and 101%, respectively.Conclusion: With its dual functionality of proton neutralization and strength restoration, this polymer offers a transformative solution for defense, chemical processing, and automotive applications requiring durability in harsh acidic environments.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e00304"},"PeriodicalIF":4.2,"publicationDate":"2025-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144367710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A custom laboratory setup was employed to analyze sensitivity, retention, dynamic response, repeatability, and long-term durability under various pressure conditions. Pure PANI sensors exhibited exceptionally high sensitivity (∼50 kPa⁻¹) in the low-pressure range (0-2 kPa), but performance degraded sharply at higher pressures. In contrast, the PVA-PANI composite sensors demonstrated a broader operating range and superior mechanical stability, with a peak sensitivity of ∼48 kPa-1 in 0 to 2 kPa and 0.62 kPa⁻¹ in the 2-20 kPa range and consistent ΔR/R retention under sustained and cyclic loading. Both sensors achieved ultrafast response and recovery times (∼0.6 ms), surpassing many reported counterparts. According to the structural analysis, the PVA component improves adhesion, suppresses microcrack formation, and maintains conductivity, accounting for increased long-term reliability. The PVA-PANI sensors displayed stable performance over 200 days of durability tests and were successfully integrated into wearable and smart home systems. Applications in walk monitoring and touch interface control demonstrated excellent step detection accuracy, mechanical resilience, and repeatable response behavior under diverse real-world conditions. These findings establish the PVA-PANI pressure sensors as strong candidates for next-generation wearable electronics and intelligent interface technologies.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e00368"},"PeriodicalIF":4.2,"publicationDate":"2025-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144367712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we propose a three-step design strategy for creating luminescent azobenzene derivatives from quantum chemical calculations. First, we introduced intramolecular hydrogen bonding between o-hydroxy groups and the azobenzene moiety, not only for stabilizing the n-orbital of azobenzene but also for suppressing photoisomerization. Second, the expansion of the π-conjugation was employed to convert the S0-S1 transition to the allowed π-π* transition. Third, we derived the fast excited-state intramolecular proton transfer (ESIPT) process, which is suitable for observing emission from azobenzene. Through these steps, we designed and synthesized azobenzene derivatives and succeeded in observing intense deep-red to NIR emission from conjugated polymers including azobenzene moieties in the main chain. Furthermore, we applied the synthesized polymers to film-type acid vapor sensors. In addition to the real-time detection ability toward acid vapor observed in our previous work, we found that the current material can discriminate whether the film was once exposed to acid vapor from the changes in luminescence and film colors. Our findings reveal that azobenzene is a potential platform for creating luminescent materials with stimuli-responsiveness according to rational molecular design.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e00371"},"PeriodicalIF":4.2,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144332213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this communication, we have showcased the synthesis of epoxy monomers derived from biobased platform chemicals, specifically 5-hydroxymethyl-2-furfural (5-HMF) and epichlorohydrin (ECH), used as starting materials. The study of its coupling reactions with CO2 and its sulfur congener COS has been evaluated utilizing a well-defined binary (salen)MX/PPNX catalyst system. It was found that the reactions with CO2 predominantly produced cyclic products, while the more reactive COS led to the formation of aldehyde functional poly(monothiocarbonate)s (PMTC) in a regioselective manner at ambient temperature. Furthermore, the post-polymerization reactions of aldehydes with primary amines bearing alkene, alkyne, and radical functional groups led to the production of corresponding imine derivatives, thereby providing a pathway to well-defined, highly modifiable polymers. This process has the potential to promote a more sustainable approach for transforming a wide array of polymeric materials while introducing desirable features such as (bio)degradability for various applications.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e00451"},"PeriodicalIF":4.2,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144332211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonetheless, their utilization for soft tissue regeneration has been limited due to their intrinsic drawbacks, such as inadequate mechanical strength, poor printability, and rapid degradation rate. Recently, various modifications and crosslinking strategies have been adopted to improve the suitability of natural polysaccharides for printing robust soft tissue constructs with improved precision and functionality. This review delves into the state-of-the-art modified polysaccharide bioinks utilized for fabricating soft tissue scaffolds. The primary focus of this review is to highlight the key chemical modification approaches, including methacrylation, sulfation, and thiolation, extensively used to alter the properties of polysaccharides for achieving optimal printability and mechanical resilience. By introducing the importance of crosslinking strategies, an important distinction between covalent and non-covalent crosslinking is discussed. Effective modification and crosslinking of the polysaccharides also allow for explicit modulation of their biofunctionality, promoting cell fate processes and facilitating the regeneration of soft tissues such as skin, cartilage, muscles, and neural tissue. We aim to provide a comprehensive understanding of the current advancements in the field and underline future perspectives in fabricating personalized tissue scaffolds for next-generation regenerative solutions.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e00236"},"PeriodicalIF":4.2,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144332212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
