The structural design, polymerization method, optical properties, and application exploration of unsaturated double-bond high-refractive index monomers are analyzed in detail. Unsaturated high-refractive index monomers (UHRIMs) comprise high molar refractive index groups and unsaturated groups. In the structural design, the main types of unsaturated double bonds are vinyl (alkyne)/allyl, vinyl ether/allyl ether, (methyl)acrylate, cyclic olefin, maleimide, and others. The type of unsaturated group determines the polymerization method employed. The main polymerization methods include thiol-ene click reaction, thermal-initiated polymerization, photo-initiated polymerization, coordination polymerization, etc. In addition, the UHRIMs have relatively small molecular weight, high solubility, and mild molding conditions, which will have potential wide applications in nanoimprint, holographic technology, thermal infrared imaging, microlenses, optical devices, waveguide materials, coatings, etc.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500037"},"PeriodicalIF":4.2,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143957319","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}

To address this issue, this work designs and synthesizes a partially crosslinked biobased and biodegradable polyester elastomer to replace the high molecular weight rubber in traditional CG for elasticity, along with a biobased biodegradable polyester resin with a glass transition temperature (Tg) of ≈38 °C to provide plasticity for CG. Subsequently, biobased biodegradable CG is prepared. Poly(1,3-propanediol/glycerol/sebacate/succinate) (PPGSeSu) elastomers with adjustable gel content and good elasticity are synthesized by adjusting the content of glycerol, and poly(2,3-butanediol/isosorbide/succinate) (PBIS) resins with a Tg of 8-65 °C are prepared by tuning the molar ratio of isosorbide and 2,3-butanediol. As a result, fully biobased, biodegradable CG with similar performance to that of commercially available ones is achieved by using PPGSeSu-25%P (with 8.58% gel content) and PB50I50S (Tg = 38 °C). The biodegradation rate of the new CG is 75.52% after 97 d, and its chewing properties are comparable to those of commercially available CG according to the texture profile analysis results.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500262"},"PeriodicalIF":4.2,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143956951","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}

This review summarizes the recent significant advances of BBPs, from synthetic methods to their versatile properties and applications in areas of super-soft elastomers, photonic crystals, self-assembly, friction, biomimetic tissues, bio-interfacial interactions to enhance cell penetration and anti-fouling performance, drug delivery, and other emerging applications (polymer electrolyte, catalyst support, and covalent adaptable networks).

The cationic pGTA scaffold not only facilitated efficient nicotinamide adenine dinucleotide (NADH) access to the FMN center, but also incorporated arginine aiming to stabilize the peroxo intermediate, mimicking the microenvironment of the active site of BVMOs. The self-assembly is confirmed through 1H-NMR, fluorescence quenching, transmission electron microscopy, the zeta potential, and molecular dynamics simulations. The FMN-based supramolecular catalysts effectively catalyzed NADH oxidation, followed by BV oxidation of cycloketones (including bicyclo[3.2.0]hept-2-en-6-one, 2-phenylcyclobutanone and 3-phenylcyclobutanone) to yield the corresponding lactone with high selectivity. The system demonstrated excellent activity under mild, oxygen-driven conditions, and its performance is further enhanced upon heating.

To address these limitations, an antibacterial conductive suture with an electrically controlled drug release system is developed in this study. Polypyrrole (PPy) doped with tannic acid (TA) is in situ polymerized on the surface of silk sutures precoated with chitosan/gelatin (CS/GE), designated as PCG-SS. The PCG-SS exhibits excellent conductivity, enabling voltage-dependent regulation of TA release. At -0.6 V applied potential, PPy underwent electrochemical reduction with decreased positive charge density, enabling maximal TA release; conversely, at +0.4 V, PPy attained an oxidized state with enhanced positive charges, strengthening electrostatic adsorption of anionic TA and achieving 80% suppression of drug elution. Under -0.6 V stimulation, the antibacterial rates of PCG-SS against S. aureus and E. coli exceeded 90%. This work successfully validated that a PPy-based drug-controlled release system can effectively formulate drug release programs, providing new insights into the study of electronically controlled drug delivery systems.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500238"},"PeriodicalIF":4.2,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143956979","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}

Sulfur-containing polymers have been studied in-depth; however, their selenium-containing analogs remain rarer. Herein, a series of polymers of low synthetic complexity with systematically increasing selenium content are presented. Three novel polymers FO6-Se, FO6-BS-T, and FO6-BS-Se are synthesized using a facile two-step protocol, combining combinations of selenophene, thiophene, benzothiadiazole (BT), and benzoselenadiazole (BS) units. The optical, electrochemical, and morphological properties of these polymers are comprehensively analyzed, revealing interesting structure-property relationships. Results show a significant bathochromic shift in absorption and emission spectra upon increasing Se content. Charge transport properties are evaluated in OTFTs, with FO6-BS-T exhibiting the highest hole mobility of 0.038 cm2V-1s-1 when annealed at 100 °C. Grazing-incidence wide-angle X-ray scattering (GIWAXS) studies reveal reduced crystallinity upon BS incorporation and density functional theory (DFT) calculations indicate increased backbone twisting upon BS inclusion compared to BT. This work demonstrates how systematic selenium incorporation alters polymer properties, particularly frontier molecular levels, and morphology, contributing to the understanding of selenium-containing scalable polymers for potential application in organic thin-film transistors.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500059"},"PeriodicalIF":4.2,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143964672","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}

It is curious about the evolution of optical properties of porous polymer films (white) after introducing carbon materials (black) with high light absorption. Will their color definitely evolve towards black? Here, ultrathin porous polymer films with brilliant whiteness, even with CB (carbon black) that absorbs visible light, are prepared from black polymer suspension by spin coating for the first time. The structure-activity relationship between their structures and optical properties is thoroughly analyzed. Further, the effects of pore size, porosity, film thickness, and CB content on the reflectance and transmittance are systematically investigated by finite-difference time-domain (FDTD) simulations. The results indicate that introducing porous structures to polymer films significantly increases their reflectance and reduces their transmittance. When CB content is low, its impact on reflectance is small or even negligible, while when it is high, it presents a negative effect. And it is negatively correlated with the transmittance. Especially, the reflectance of porous PS (Polystyrene)/CB films containing 0.001 g CB is even higher than that of pure porous PS films, which does not occur in FDTD simulations, attributed to the porous structure reinforcement from CB in actual experiments.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500205"},"PeriodicalIF":4.2,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143959526","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}

The recycled polymers are suitable starting materials for the reuse in automotive interior applications. Specifically, this work focuses on changes in thermal, morphological, rheological and mechanical properties caused by the recycling process. Fabric back-injected polycarbonate (PC) based blends are semi-automatically produced, shredded, pre-dried and granulated using a single-screw extruder. TEM images of the recycled materials show a fine droplet phase distribution of textile polyethylene terephthalate (PET) in PC, PC blend respectively, as well as the formation of a PET matrix in a neat PC/PET blend. DSC analyses indicated a shift in glass transition temperatures, suggesting partial miscibility of the blends. Compounding of textile PET with PC based blends led to decrease in viscosity at 280 °C. The blends show a slight decrease in strength and strain at break, due to hindered plastic deformation in PC blends, but increase of strength and strain at break of neat PC/PET due to PET becoming the matrix phase. This work highlights the potential of a partial miscibility of textile PET and polycarbonate which is used for a novel recycling approach for textile covered bezels contributing to sustainability by reducing waste and costs.","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500165"},"PeriodicalIF":4.2,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143952868","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}
