In 2020, the MOE key laboratory of macromolecular synthesis and functionalization in Zhejiang University had made progresses in several aspects. First, a series of metal-free organoboron catalysts had been designed and synthesized facilely, exhibiting outstanding reactivity, thermalstability and productivity in different kinds of polymerization and cycloaddition reactions. Second, a variety of chalcogen(O, S, Se)-rich polymers had been synthesized via organocatalysis and fabricated to be the ionic conductive and photoluminescent materials. Third, diverse microenvironment-sensitive nanoparticles had been designed,and novel strategies had been realized, to enhance the therapeutic efficacy in cancer as well as biofilmassociated infections. Fourth, m6 A modification on cellular transcriptome-wide messenger RNA had been successfully mapped at single base resolution using a metabolic labeling method. Fifth, a hydrogel-based robot had been developed, showing swift locomotion as a response to dynamic light stimulations. Sixth,the conformation-size scaling law and the conformation evolution map of 2 D macromolecules in solution had been elucidated experimentally, in the single-layer graphene oxide model. Seventh, semitransparent polymer solar cells, promising as building-integrated photovoltaics, have been developed with the fine balance among power conversion efficiency, visible light transparency and infrared photon radiation rejection. Finally, long-range ordered bulk-heterojunctions of organic semiconductors had been achieved,and their superior optoelectronic properties and potential application in photoelectric conversion had been revealed. The related work progresses are reviewed in this paper.

Halogen-Free Epoxy with Enhanced Corrosion Resistance for Microelectronics Packaging via γ SN2 Nucleophilic Substitution

Bisphenol A diglycidyl ether (DGEBA) is an essential epoxy resin in the microelectronics industry. However, circuit corrosion caused by hydrolyzable chlorine─a persistent issue associated with DGEBA─poses significant challenges in this field. In this study, we present a novel strategy for producing halogen-free DGEBA with high purity (up to 99%) and isolated yield (up to 94%) by utilizing glycidyl sulfonates as the starting material. A distinctive γ SN2 nucleophilic substitution pathway between glycidyl sulfonates and phenolic compounds effectively suppresses the formation of ring-opening byproducts and oligomers, as demonstrated through model reactions and kinetic studies. The scalability and versatility of our method are validated by its straightforward synthesis process and expanded substrate scope. Finally, the halogen-free DGEBA exhibits noncorrosive properties when employed as a matrix resin for prepreg and underfill applications. Our research underscores the potential of glycidyl sulfonate as a viable alternative to epichlorohydrin in large-scale epoxy production for electronics. © 2025 American Chemical Society.

CO_(2)-Sourced Poly(chloropropylene carbonate) with High Flame-Retardant Performance

The alternating copolymer of CO_(2) with epoxide is a green plastic that can efficiently transform CO_(2) into valuable chemicals. Despite the significant advances made, the restricted practical application of CO_(2)-sourced polycarbonates due to their lack of functionality has hindered field development. We successfully demonstrated the flame retardancy of poly(chloropropylene carbonate) (PCPC), a perfectly alternating copolymer of epichlorohydrin (ECH) and CO_(2). This was prepared at a 200-gram scale using a high-efficacy tetranuclear organoborane catalyst. PCPC’s excellent flame-retardant performance has been proven by both the vertical combustion test (UL94 V-0) and the limiting oxygen index (LOI) value (29.1%). The underlaid flame-retardant mechanism of PCPC was clearly elucidated. As a result, we confirmed that the generated cyclic carbonates and concurrently released flame-retardant chlorine radicals, hydrogen chloride, and CO_(2) during combustion render PCPC an excellent flame retardant. Furthermore, we investigated the practicability of PCPC as a halogen-rich polymeric flame retardant by blending it with commercial bisphenol A polycarbonate (BPA-PC). PCPC upgraded the flame retardancy rating of BPA polycarbonate from V-2 to V-0 even with a mere 1 wt% addition. It is our hope that this result will prove useful in future developments of advanced CO_(2)-sourced polymeric materials.

A highly transparent dopamine-copolymerized hydrogel with enhanced ROS-scavenging and tissue-adhesive properties for chronic diabetic wounds

Acta Biomaterialia 2025年 198卷 161-173页

Chronic diabetic wounds with complex symptoms represent a major challenge in clinical practice, causing a serious threat to human health and life. Excessive oxidative stress and persistent inflammatory responses are the important reasons for the long-term difficult healing of diabetic wounds. Designing wound dressing materials with intrinsic antioxidant performance, high transparency, adhesiveness, and favorable mechanical properties is of great significance for promoting wound healing, especially in movable parts. Here, a dopamine-copolymerized highly transparent antioxidant hydrogel was developed for the treatment of chronic diabetic wounds. The hydrogel was easily prepared via free radical polymerization using acrylated dopamine monomer (ADA), acrylamide (AM), and phenylboronic acid modified dextran (DP). The dynamic phenylborate ester bonds formed between the catechol of polydopamine and phenylboronic acid effectively mitigated the darkening of the hydrogel color caused by the auto-oxidation of catechol, resulting in the PAM/PDA/DP hydrogel (DP3) with durable transparency. In addition, this hydrogel had good adhesiveness and mechanical properties, as well as desirable reactive oxygen species (ROS)-scavenging performance. Furthermore, in vivo results demonstrated that DP3 hydrogel can stimulate the polarization of macrophages toward anti-inflammatory M2 phenotype, increase the secretion of anti-inflammatory factors, so as to smooth the transition of wound healing from the inflammatory phase to the proliferative phase, and accelerate the repair of diabetic wounds by promoting angiogenesis and collagen deposition. Therefore, the DP3 hydrogel holds great potential for remolding the tissue regeneration microenvironment and serving as a promising dressing for chronic diabetic wounds. Statement of significance: Polydopamine (PDA)-based hydrogels have been widely explored. However, existing PDA-based hydrogels suffer from low content of catechol groups and inferior tran

Alkaline phosphatase-responsive lipid-like polyphosphonitrile nanovesicles to enhance immunotherapy and inhibit metastasis of triple-negative breast cancer

引用

Chemical Engineering Journal 2025年 515卷

Triple-negative breast cancer (TNBC) is associated with high invasiveness and mortality, with current immunotherapies offering limited clinical benefits. Reduced tumor immunogenicity and dendritic cell (DC) dysfunction are major contributors to tumor immune evasion. Herein, an alkaline phosphatase (ALP)-responsive nanovesicle system (P-DOX/IFN-γ), based on lipid-like polyphosphonitrile (PEBP), was developed for the co-delivery of doxorubicin hydrochloride (DOX) and interferon-γ (IFN-γ), aiming to enhance the therapeutic efficacy against TNBC. The phosphate ester structure facilitates nanovesicle formation and enables multiple interactions with both drugs, thereby efficiently achieving the synchronous encapsulation of DOX within the membrane and IFN-γ in the aqueous cavity. P-DOX/IFN-γ exhibits enhanced tumor targeting and ALP-responsive drug release within the tumor microenvironment. Mechanistically, DOX induces immunogenic cell death in tumor cells, while IFN-γ induces cell cycle arrest and upregulates major histocompatibility complex class I (MHC I) expression, synergistically enhancing tumor immunogenicity and promoting DC activation. As a result, P-DOX/IFN-γ significantly amplifies antitumor immunity and reduces long-term postoperative metastasis in the orthotopic 4T1 tumor model. Overall, this study provides a versatile nanoplatform and a promising immunotherapeutic strategy for TNBC and other poorly immunogenic tumors. © 2025 Elsevier B.V.
