Porous polymers have emerged as a prominent frontier in contemporary polymer science.This is not only because they expand the structural boundaries of synthetic macromolecular materials,but more importantly because they provide a uniquely powerful platform for precisely controlling matter and energy at the molecular scale.Encompassing covalent organic frameworks(COFs),conjugated microporous polymers(CMPs),porous organic polymers(POPs),and polymers of intrinsic microporosity(PIMs),these materials integrate permanent porosity,modular chemical design,tunable electronic structures,and,in some cases,long-range order within a single framework. 展开更多

Self-immolative polymers(SIPs)have recently emerged as a distinct class of stimuli-responsive materials that undergo programmed domino-like degradation in response to specific biochemical triggers.The unique biochemical characteristics of the tumor microenvironment(TME)include acidic pH,elevated glutathione(GSH)levels,excessive reactive oxygen species(ROS),dysregulated enzymes,and hypoxia.TMEresponsive SIPs have attracted significant attention for precise cancer imaging and therapy.By integrating labile linkages and modular structural design,these polymers can amplify weak biochemical signals into robust responses,enabling controlled drug release,signal amplification in imaging,and multifunctional theranostics.Compared with conventional responsive systems,SIP-based nanoplatforms offer enhanced sensitivity,tunable degradation kinetics,and the potential for sequential or cascade activation.In this review,we provide a comprehensive overview of the design principles,activation mechanisms,and functional applications of TME-responsive SIPs.We highlight representative strategies for their use in targeted drug delivery,tumor imaging,and synergistic therapeutic approaches and discuss the incorporation of emerging modalities such as near-infrared II(NIR-II)imaging and combination immunotherapy.Finally,we outline the major challenges and opportunities for advancing SIP-based nanomedicines for clinical translation and offer perspectives on how this rapidly evolving field may reshape the future of precision cancer diagnosis and treatment. 展开更多

In the context of the continuously increasing energy demand,the ongoing advancement of innovative energy storage technologies is regarded as an important strategy to alleviate the energy crisis.Among various energy storage technologies,supercapacitors(SCs)demonstrate significant potential in the future energy storage sector due to their exceptional high-power density and long cycle life.As the core component of SCs,the choice of electrode materials is crucial to their performance,with carbon materials being favored for their excellent electrical conductivity and large specific surface area.In particular,porous carbon materials derived from biomass-based polymers have become a research hotspot due to their unique advantages.Through chemical modification and high-temperature carbonization,these materials can form more stable and optimized porous structures,significantly enhancing their electrochemical performance while meeting environmental protection requirements,thereby highlighting their superiority as electrode materials.This article aims to review the sources,production,and applications of carbon materials derived from biomass-based polymers.We have deeply summarized the preparation and activation methods of carbon from different biomass-based polymer sources.In addition,a comprehensive analysis and systematic comparison of novel modification techniques,such as heteroatom doping,copolymerization,and the incorporation of nanomaterials,were performed to enhance the performance of SCs.Finally,according to the technical challenges to be solved,the goal of large-scale development of biomass-based polymerderived porous carbon in the field of energy storage is proposed,which is crucial for coping with the global energy crisis and reducing environmental impact. 展开更多

Liver is a vital organ in the human body and plays a central role in the metabolism and detoxification of endotoxins and exotoxins.Bilirubin is an endotoxin derived from hemoglobin(Hb).Removing excess bilirubin in the blood is crucial for the treatment of liver diseases.Hemoperfusion,which relies on adsorbents to efficiently adsorb toxins,is a widely applied procedure for the removal of blood toxins.To broaden and improve the range and performance of hemoperfusion adsorbents,we synthesized cationic hyper crosslinked polymers(HCPs)with strong affinity for bilirubin.This material exhibited outstanding adsorption performance,with a maximum adsorption capacity of 934 mg/g and a removal efficiency of 96%.Further investigation confirmed their excellent selectivity,reusability,and biocompatibility.These findings expand the potential applications of HCPs and provide insight into strategies for constructing promising hemoperfusion adsorbent materials. 展开更多

In this study,a series of poly(ethylene succinate)-b-poly(butylene carbonate)(PES-b-PBC)multiblock copolymers were prepared through the chain-extension reaction of hydroxyl-terminated PES(PES-OH)and hydroxyl-terminated PBC(PBC-OH)prepolymers with 1,6-hexmethylene diisocyanate(HDI)as a chain extender.The effects of the prepolymer molecular weight and content on the structure and application properties of the PES-b-PBC copolymers were systematically investigated using various techniques.It was found that the compatibility of PES and PBC blocks in PES-b-PBC copolymers can be greatly enhanced by lowering the length of the prepolymers,and the amorphous phase of the PES and PBC chain segments in the PES-b-PBC copolymer would transform from immiscibility and partial miscibility to miscibility when the number-average molecular weight(Mn)of the PES-OH and PBC-OH prepolymers is less than 2000 g/mol.Only the crystal structure of bare PES can be observed in the wide-angle X-ray diffraction(WAXD)spectrum of the PES-b-PBC copolymers,but their crystallinity degrees were found to decrease with increasing PBC fraction.The thermal behavior,crystallization performance,rheological properties,mechanical properties,and degradation properties of the PES-b-PBC multiblock copolymers can be easily modulated by altering the block length and composition of the prepolymers,offering potential applications in biodegradable materials. 展开更多

Azobenzene-containing polymers(azopolymers)exhibit photoinduced reversible solid-to-liquid transitions,enabling unique light-assisted nanoimprint lithography(NIL).Cis azopolymers possess sub-room-temperature glass transition temperatures(Tg),exhibiting liquid-like behavior for flow processing,while trans azopolymers feature above-room-temperature Tg values that enable solid-state shape fixation.Although many side-chain azopolymers demonstrate photoswitchable Tgs,conventional short-spacer derivatives show negligible switching in Tg as their cis isomers remain solid.This work overcomes this limitation in ethylene-spacer azopolymers through extended alkyl tails.We synthesized tailless(P0),n-butyl-tailed(P4),and n-decyl-tailed(P10)derivatives,revealing that only P10 exhibits a cis Tg near room temperature(22℃)and an amplifiedΔTg between its cis isomer and trans isomer.P10 with photoswitchable Tgs enables complete nanostructure replication as a nanoimprint lithography photoresist.This work demonstrates that long alkyl tails counteract short-spacer limitations,effectively reducing the Tg of cis azopolymers and establishing a design principle for nanoimprint photoresists with photoswitchable Tgs. 展开更多

Conjugated microporous polymers(CMPs)have demonstrated significant potential for gas separation due to their permanent microporosity,high adsorption capacity,and exceptional chemical robustness.However,the scalable,cost-effective and environmentally friendly synthesis of CMPs as an alternative to energy-intensive traditional solvothermal methods remains underexplored.Herein,we present a solvent-free,flux synthesis method for constructing olefin-linked amorphous CMPs(NKCMP-1 and NKCMP-2)through Knoevenagel condensation of 2,3,5,6-tetramethylpyrazine with linear aromatic aldehydes.This method surpasses ionothermal and mechanochemical routes in terms of scalability and product uniformity.Notably,NKCMP-1 can be synthesized on a kilogram scale(0.54 kg)while maintaining structural integrity,high surface area and a uniform microporous architecture.Both NKCMP-1 and NKCMP-2 exhibit outstanding C2H2/CO2selectivity and cyclic stability under ambient conditions,as confirmed by dynamic breakthrough experiments.These features make the developed CMPs highly promising for real-world industrial gas purification applications. 展开更多

Cu(I)halide scintillators have emerged as promising alternatives to conventional X-ray imaging materials,owing to their high luminescence efficiency,structural tunability,and solution processability.Among them,one-dimensional(1D)Cu-I coordination polymers(CPs)not only possess excellent X-ray absorption performance and structural diversity,but also exhibit enhanced stability attributed to their continuous inorganic chain frameworks.However,low radiative efficiency remains a core bottleneck hindering the optoelectronic applications of 1D copper iodide CPs.In this study,ligand halogen engineering is synergistically integrated with the thermally activated delayed fluorescence(TADF)mechanism:halogen electron-withdrawing effects tune the singlet-triplet energy gap(ΔEST),while the heavy atom effect boosts orbital coupling,promoting TADF and enabling efficient exciton harvesting.Additionally,the electron-withdrawing property of halogens can further reduce the repulsion between Cu and I,suppressing non-radiative transitions and thereby synergistically enhancing the optical performance and light conversion efficiency of the materials.Herein,two 1D Cu-I CPs were successfully synthesized by introducing different halogen atoms into the ligands:[CuI(3,5-2Cl-py)]n(SC-Cl,where 3,5-2Cl-py=3,5-dichloropyridine)and[CuⅠ(3,5-2Br-py)]n(SC-Br,where 3,5-2Br-py=3,5-dibromopyridine).Performance characterizations demonstrate that the light yields of SC-Cl and SC-Br reach 14144.4 and 11005.1 photons MeV-1,respectively.The flexible scintillation screens fabricated from these two materials achieve high spatial resolutions of 18.8 and 16.0 lp mm-1 in X-ray imaging.This work not only provides an effective strategy for optimizing the performance of 1D scintillators but also highlights their potential applications in medical diagnosis and security inspection fields. 展开更多

Perovskite solar cells(PSCs)have achieved remarkable power conversion efficiencies(PCE)exceeding 27%,while their operational instability under environmental stress(e.g.,moisture,heat,mechanical bending)remains a critical barrier to commercialization.Self-healing polymers(SHPs)with dynamic covalent bonds or noncovalent bonds have emerged as an innovative solution to enhance the durability of PSCs through autonomous damage healing.Although SHPs have been proved to be quite promising for enhance the reliability of PSCs,there is still lacking systematic molecular design strategies tailored for practical cooperation SHPs with versatile types of PSCs.Herein,this review systematically organizes the recent research progress of self-healing PSCs from the perspective of application-oriented design principles.The self-healing mechanisms of PSCs using SHPs under chemical and mechanical damage modes are first comprehensively explored,and a multi-dimensional self-healing evaluation system is proposed.Subsequently,the distinct effects of SHPs as additives,interfacial modifiers,and encapsulation materials in PSCs are summarized.More importantly,the incorporation methods of SHPs in PSCs and the structural characteristics of representative SHPs are systematically analyzed,with application-specific design principles for optimized performance proposed.Finally,the challenges and opportunities in the optimization of self-healing material properties,in situ characterization techniques,and scalable fabrication are outlined.This work aims to facilitate the transition of SHP-based self-healing PSCs from laboratory research to real-world applications,providing a roadmap for future developments in this emerging field. 展开更多

The growing global demand for sustainable energy makes biodiesel an important renewable alternative to alleviate the energy crisis and reduce greenhouse gas emissions.Therefore,there is an urgent need to develop efficient,environmentally friendly and economically viable biodiesel production methods.Hypercrosslinked polymers(HCPs),as aromatic porous organic polymers,are solid frameworks that can be used as heterogeneous catalyst,and they are a promising platform for biodiesel catalytic conversion due to their low cost,highly accessible active site,tunable catalytic site types.In addition,innovative green synthesis strategies make environmentally begin production of HCPs possible.In recent years,HCPs has developed rapidly in the field of biomass catalysis.Unfortunately,to the best of our knowledge,there are no publications focusing on the green synthesis and application of HCPs-based materials for biodiesel production.This review provides an update on the synthesis and utilisation of green and efficient HCPs for catalytic biodiesel production.Initially,the green routes for HCPs synthesis are described,followed by a comprehensive summary of the various approaches to biodiesel production.The primary focus is on the utilisation of HCPs as carriers of active sites in the catalytic conversion of biodiesel,with particular emphasis on catalyst design,morphology control,and intelligent management in terms of application extension.Ultimately,thought-provoking recommendations are proposed to utilize improved green HCPs in combination with advanced production processes to achieve more efficient and sustainable development. 展开更多

Acceptorless dehydrogenative coupling of pyridinemethanol with ketones is one of the most reliable methodologies to access functionalized 1,8-naphthyridine derivatives.However,it is challenging to develop environmentally friendly catalytic systems,especially in constructing efficient and recyclable catalysts under water or solvent-free conditions.Here,we designed two novel coordination polymers Cd-CPs and Fe-CPs to investigate their catalytic performance in water.Gratifyingly,it was observed that Cd-CPs as a multifunctional catalyst was successfully applied to establish a universal pathway for direct fabrication of 1,8-naphthyridine derivatives under water conditions,while it was effective for the synthesis of1,3,5-triazines through acceptorless dehydrogenative coupling strategies.The features of broad substrate,high atom efficiency,and good catalyst reusability highlight the feasibility of this transformation.In additional,we demonstrated the spindle-like structures Fe-P,derived from the Fe-CPs via phosphorylation,which can be used as an efficient electrocatalyst for oxygen evolution reaction with good stability.This work provides two highly efficient non-noble metal catalysts for functionalized 1,8-naphthyridine derivatives production and oxygen evolution reaction,and opens a new avenue to further fabricate diverse metal catalysts with high catalytic performance in water. 展开更多

The utilization of CO2 resources is an important way to mitigate excessive release of CO2 and addressing energy shortages.In this work,a series of metal-and halogen-free imidazole-based hypercrosslinked polymers(HCPs)featuring hydrogen bond donors were constructed by one-step Friedel-Crafts alkylation using imidazole derivatives 4-(imidazole-1-yl)aniline(PYIM-NH2)and 4-(imidazole-1-yl)phenol(PYIM-OH)containing hydrogen bond donors(―NH2,―OH)as functional monomers.The synthesized HCPs possess a high specific surface area,an abundance of multi-level pore channels,and excellent adsorption capacity and selectivity for CO2.The optimal catalyst Imi-HCP-NH2(14:1)synthesized using PYIM-NH2 as the functional monomer demonstrates a high catalytic activity for fixing CO2 into cyclic carbonates under additive-free conditions.Notably,the catalyst exhibits a satisfactory catalytic activity even under diluted CO2 concentration and mild conditions.The excellent catalytic performance,along with good cycling stability and the broad applicability of epoxides,make it a competitive catalyst for catalyzing the CO2 cycloaddition reaction. 展开更多

Antibiotics,as an emerging pollutant due to their extensive use and difficulty in biodegradation,can cause harm to health through bioaccumulation.To address this,various photocatalysts have been developed for rapid antibiotic removal.However,their low concentrations limit mass transfer efficiency,resulting in suboptimal performance.Adsorption is crucial for enhancing photocatalytic efficiency.In this study,a series of binary heterojunction catalysts(x%BWO@STHP)were synthesized,consisting of Bi2WO6(BWO)grafted with sulfonated triptycene-based hypercrosslinked polymer(STHP).The high specific surface area of STHP,combined withπ-πconjugation and ionic interactions with antibiotics,significantly enhances adsorption capacity.This facilitates effective contact between low-concentration pollutants in aqueous solutions and the active sites of the catalyst.The formation of a Z-scheme heterojunction between BWO and STHP facilitates photogenerated charge separation,and further significantly improves photocatalytic degradation performance.Specifically,the 20%BWO@STHP catalyst achieved rapid adsorption equilibrium for oxytetracycline(OTC),doxycycline(DOX),and tetracycline(TC)within 2 min and completely degraded them after 15 min of irradiation.Compared to pristine BWO,the photocatalytic reaction rate constants are significantly increased,being 9.69 times higher for OTC and 13.45 times higher for DOX.The catalyst exhibits excellent reusability and holds promising potential for practical applications. 展开更多

Pure organic room-temperature phosphorescent(RTP)polymers possess good processability and flexibility over small molecular crystals.However,most of RTP polymers reported so far are based on non-conjugated polymers,and achieving efficient phosphorescent emission in RTP conjugated polymers(CPs)remains a significant challenge.Herein,we developed two RTP CPs(P(PSe ZPh-p-Ph)and P(PSe ZPh-m-Ph))by linking the phenoselenazine units with the para-and meta-phenylene units,respectively,to form the conjugated main chains.The phenylene linker with different lingking mode manipulates the effictiveπ-conjugation of the polymer backbones.Comparing with the para-linked P(PSe ZPh-pPh),meta-linked P(PSe ZPh-m-Ph)exhibit the decreased effectiveπ-conjugation and the enhanced contribution of selenium atoms to the frontier orbitals,leading to the larger spin-orbit coupling(SOC)constants and the accelerated phosphorescence radiative decay process.The P(PSe ZPhm-Ph)achieves a phosphorescence quantum yield of 21.4%in doped polystyrene films,which is among the highest efficiencies reported to date for pure organic RTP CPs.These CPs are applied to construct phosphorescent film sensors for oxygen detection with the high quenching constants(Ksv)up to 14.80 kPa-1and low detection of limit of 0.84 ppm,demostrating the potential for application in oxygen film sensors. 展开更多

Redox-active covalent organic polymers(COPs)have emerged as appealing renewable electrode materials for next-generation Li-ion batteries,but their performance is limited by insufficient redox sites and inadequate Li-ion diffusion.Here,we develop a novel class of mesoporous covalent organic polymer(namely TF-Azo-COP)bearing multiple redox sites and explore its first use as efficient 18-electron-redox anodes for superior Li-ion storage in both coin-type and fiber-type batteries.The newly produced TF-Azo-COP involves three types of active sites including C=N in triazines and imines,N=N in azo,and C6-ring aromatics to enable 18-Li-ion storage on one repeatable segment,while affording extendedπ-conjugation for fast electron transfer and a pore size of~2.5 nm for facilitated ion diffusion with a high coefficient up to~10-10cm2s-1—superior to some reported organic electrodes.Meriting from the above,pairing TF-Azo-COP with metal Li endows a coin cell with good cycling stability and a large reversible capacity of 795.4 mAh g-1at 0.1 A g-1—representing one of the best performances among reported organic electrodes.When coupled with fiber-shaped LiFePO4cathodes,the assembled fiber cell delivers an excellent combination of linear capacity(0.23 mAh cm-1),energy density(0.55 mWh cm-1),cycling stability(250 cycles),and good flexibility. 展开更多

Coal tar(CT)has potential applications as a carbon material precursor due to its malleability and high carbon content.However,the low carbonization rate of CT is a major constraint to its development.In this work,a microporous carbon material(CF2CT)is synthesized from CT via the Friedel–Crafts alkylation reaction,which results in a significant increase in the carbonization yield(68%).In the absence of an activator,the CF2CT showed specific surface areas(766 m2 g-1)and micropore volumes(0.32 cm3 g-1),with pore diameters mainly centered on 0.5–0.8 nm.The CF2CT exhibited an excellent gravimetric capacitance of 342 F g-1 under 1 A g-1 in a three-electrode system,while its capacitance remained approximately 98%over 10000 cycles under 10 A g-1.The symmetrical supercapacitors fabricated with CF2CT showed a 7.8 Wh kg-1 energy density and a 250 W kg-1 power density,with capacitance remaining up to 100%at 10 A g-1 after undergoing 10000 cycles.This study proposes an idea for the preparation of high-yield carbon precursors from coal tar while also offering a promising HCP-derived carbon material for supercapacitor electrodes. 展开更多
