Utilizing the conjugated backbone structure and ICT mechanisms, several novel D-A type polymers were designed and synthesized using thiophene, strong fused-ring thiophene donors (IDT or IDTT), ultrastrong acceptor units (benzobisthiadiazole derivatives (SNT) or benzothiadiazolo[3,4-g]quinoxaline (TQX)), and acceptor benzothiadiazole (TZ) as the building blocks for constructing broad-band absorption electrochromic polymers. The incorporation of SNT (or TQX) units into the polymer chain induces the NIR modulation, while the combination of TZ units fulfills the long-wave visible absorption for synergistic visible and near-infrared (NIR) modulation of the polymers. Consequently, the synthesized polymers and derived electrochromic devices demonstrate ultra-broad electrochromism from 350 nm to 1000 nm with high optical contrast, swift switching response and good stability, which presents great application potential in smart windows.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":"67 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we present a novel approach utilizing neodymium-catalyzed coordinative chain transfer polymerization (CCTP) to construct end-functionalized PIps with distinct functional groups at the α- and ω-termini. The α-end functionalization was achieved by incorporating copolymerizable heteroatomic 1-substituted dienes (BdPhX) during the aging stage of polymerization. By varying the type and feed ratio of BdPhX, a diverse array of α-functional moieties with tunable incorporation levels was readily obtained. Detailed kinetic studies revealed that the presence of α-functional BdPhX moieties exerted minimal impact on the CCTP process, maintaining highly reactive allyl–metal bonds (predominantly allyl–Al bonds) crucial for subsequent ω-end functionalizations. The ω-end functionalization was realized through two complementary strategies: (1) the incorporation of copolymerizable diene derivatives and (2) in situ reactions with reactive small molecules. The first approach was achieved by introducing BdPhX monomers, while in the second approach, reactive small molecules such as isothiocyanates and oxygen, were employed to construct thioamide and hydroxyl end-functional groups, respectively. The synthesized polymers were comprehensively characterized to confirm their structures and functionalities, highlighting the versatility and efficiency of this strategy for designing α,ω-end hetero-functionalized PIps.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":" 14","pages":" 1556-1567"},"PeriodicalIF":4.1,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143538680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a series of composites DBDSO/g-C3N4-x (x = 10, 15, 20, and 30) were synthesized by combining different proportions of g-C3N4 with DBDSO using the solvent dispersion method. The donor–acceptor (D–A) type conjugated porous polymer (CPP), named DBDSO, was synthesized through the Suzuki coupling reaction between dibenzothiophene-S,S-dioxide (DBTSO) and 4,8-di(thiophen-2-yl) benzo[1,2-b:4,5-b′] dithiophene (DBD). Optoelectronic measurements and theoretical simulations revealed that the formation of S-scheme PHJs facilitated efficient separation and transport of photo-generated carriers, resulting in a decrease in fluorescence lifetimes from 3.78 ns in pure g-C3N4 to 2.63 ns in the DBDSO/g-C3N4-15 composite. As a result, DBDSO/g-C3N4-15 exhibited significantly enhanced PHP performance compared to pure g-C3N4 catalysts without any precious metal co-catalyst addition, achieving an impressive hydrogen evolution rate (HER) of 80.75 mmol g−1 h−1. Additionally, DBDSO/g-C3N4-15 demonstrated good photocatalytic stability with an apparent quantum yield of 3.88% at a wavelength of 420 nm. This work presents a promising approach for enhancing the photocatalytic HER through rational structural design to regulate charge transfer.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":" 14","pages":" 1603-1612"},"PeriodicalIF":4.1,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143538501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these, lactic acid has emerged as a pivotal platform chemical for synthesizing high-value derivatives. The chemical depolymerization of polylactic acid (PLA) into lactate esters and amides represents a straightforward and efficient strategy for upcycling PLA waste into specialty polymers. In this study, we developed a mini-library of lactate amide-based acrylic monomers using commercially available PLA bags as feedstock. These monomers were polymerized into homo, statistical, and block copolymers via Cu(II)Br2/Me6TREN-mediated polymerization under UV light. The resulting polymers exhibited water solubility adjustable through amide N-substitution combined with low ecotoxicity. This innovative approach not only advances sustainable PLA waste management but also opens new possibilities for designing advanced thermoresponsive polymers with single or double phase separation behaviors—an underexplored frontier in biobased synthetic polymer research.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":"13 6 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143507204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, developing recyclable functional materials from biomass is crucial. Here, we confirmed the reversible exchange ability of dithioacetal bonds through a model compound exchange reaction. Crosslinked polydithioacetal (PDTA) was prepared via solvent-free polycondensation of biomass benzaldehyde and tetra-thiol monomers at room temperature. Self-healing and multi-mode recycling, including mechanical reprocessing, chemical recycling, and back-to-monomer recycling, were achieved under mild conditions with no mechanical performance reduction. The solid-state plasticity due to the dynamic nature of polydithioacetal endowed PDTA with reconfigurable shape memory capability, which ensured the flexible application of PDTA by allowing reconfiguration of its permanent shape and recovery route direction. Moreover, the activation temperature for shape memory can be facilely tuned by adjusting the crosslinking densities of PDTA to meet medical application needs. With its facile tunability, great hydrolytic resistance and biocompatibility, PDTA exhibited outstanding performance in a vascular stent demonstration experiment, in which a shrunken stent made of body temperature-responsive PDTA expanded and provided support within the vessel, showing the promise of PDTA as an environmentally and biologically friendly material for the implanted biomedical stent.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":" 14","pages":" 1595-1602"},"PeriodicalIF":4.1,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influence of the trifunctional initiator's reactivity on the resulting polymer topology was investigated. The bromo-terminated PS was efficiently converted to its azide-terminated counterpart as confirmed by online ATR FT-IR and NMR spectroscopy. The targeted amine-terminated PS was then obtained by a Staudinger reduction of the azide groups using tributylphosphine. To assess the applicability of these novel amine-terminated PSs as well-defined trifunctional crosslinking agents, traditional epoxy thermoset networks and covalent adaptable networks (CANs) were synthesized using diepoxides or diacetoacetates, respectively. The resulting materials exhibited excellent thermal resistance, attributed to the high PS content. Moreover, by making use of the option of tuning the molar mass of such macromolecular crosslinkers, the network's crosslinking density could be tailored, enabling control over swelling degree, glass transition temperature, and, in the case of the obtained vinylogous urethane vitrimers, even reprocessability.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":" 14","pages":" 1546-1555"},"PeriodicalIF":4.1,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/py/d5py00098j?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143486564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
