Here, we introduce the development of a hierarchical-responsive therapeutic agent self-assembled from phenylboronate ester-linked Tjernberg's KLVFF peptide-curcumin conjugates (CPKNAs), which is designed to dynamically track the spatiotemporal coordinates of biomarkers associated with AD heterogeneity in progression. The dynamic covalent phenylboronate ester bond undergoes varying degrees of dissociation in response to the temporal evolution patterns of amyloid-β, reactive oxygen species, and glucose, three key indicators for staging AD progression, enabling self-adaptive regulation of drug distribution and dosing tailored to specific phenotypes. Employing seven cellular models and three types of transgenic mice simulating different AD stages, we demonstrate that CPKNAs effectively minimize the risks of under- or overtreatment, achieving consistent therapeutic outcomes in mitigating cellular damage and improving brain dysfunction.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e16343"},"PeriodicalIF":26.8,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147830799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its production through solar energy and metal-free photocatalysts is desirable. Organic semiconductors, as a new generation of semiconductors, can form suitable transition state intermediates showing great ability in enhancing the efficiency and selectivity of photocatalytic H2O2 generation, offering a metal-free, green, and more economical solution. However, the smaller Frenkel exciton radius and larger exciton Coulomb binding energy lead to a constrained capacity for exciton dissociation, blocking the way of photocatalysts based on organic semiconductors. Here, we overcome the bottleneck by cocrystal engineering. A kind of cocrystal photocatalysts with X-packing are designed and synthesized, which permit all excited states to be optically allowed due to reduced energy splitting, enhancing the exciton participation in photosynthesis of H2O2 giving much more efficient singlet exciton dissociation and exciton utilization. Indeed, the X-packed cocrystals show photosynthesis of H2O2 from O2 and H2O at a rate of 2.65 mmol h-1 g-1 and a solar-chemical energy conversion efficiency of 0.42%, which can be further improved to 13.3 mmol h-1 g-1 with a hole sacrificial agent.

High-entropy TMDs, in which local lattice distortion and charge redistribution occur within a van der Waals layered structure, are expected to overcome these intrinsic limitations by improving catalytic activity, photocarrier dynamics, and phase stability. Here, we demonstrate a wafer-scale 2D high-entropy (MoWTaNbRu)S2 thin-film catalyst with distorted 1T phase on p-Si photocathode for PEC-HER. The high-entropy effect induces substantial electronic redistribution, enhancing the contribution of d-orbitals near the Fermi level and optimizing hydrogen adsorption energetics. PEC kinetic analyses, including intensity-modulated photocurrent spectroscopy, demonstrate that (MoWTaNbRu)S2 markedly suppresses the recombination of photogenerated charge carriers, enabling more efficient charge extraction and accelerated interfacial reaction kinetics. Furthermore, the high-entropy-driven stabilization of the metastable 1T phase ensures excellent durability of the photocathode. As a result, the (MoWTaNbRu)S2/TiO2/p-Si photocathode shows a remarkable photocurrent density and stability for over 100 h, outperforming single-metal TMDs.

Here, the film anode (Fe@Fe3O4/CNTs) and cathode (NiCo-NiCo compound/CNTs) were prepared by the vacuum filtration technology. Density functional theory calculations combined with experimental results revealed that oxygen vacancies can induce the formation of dense localized charge aggregation regions at the Fe/Fe3O4 interface, significantly enhancing the charge transfer rate in electrochemical reactions, enabling the anode to achieve a specific capacity of 7.88 F cm-2 (749.1 C g-1) at a high mass loading of 16.7 mg cm-2. Meanwhile, after introducing oxygen vacancies, the adhesion energy at the interface significantly increased, enhancing the binding strength between Fe and Fe3O4, making it less prone to peeling due to current shock during long-term charge and discharge cycles, thereby improving the cycling stability of the Fe-based anode (76% capacitance retention after 20 000 cycles).

Their deployment, however, is limited by sluggish Zn2 + desolvation at the anode/electrolyte interface and sluggish redox kinetics of bromine species at the cathode. In this work, we developed a dual-site catalytic interface that selectively accelerates interfacial kinetics without altering the bulk electrolyte. On the anode-facing side, the indium acetylacetonate molecules provide soft Lewis acid In3 + sites that weakly coordinate with water and interact with solvated Zn2 +, effectively lowering Zn2 + desolvation energy and enabling uniform, dendrite-free zinc deposition. On the cathode-facing side, the copper acetylacetonate molecules offer redox-active Cu2 +/Cu+ sites that catalyze the Br0/Br- conversion, accelerating reaction kinetics and improving reversibility. As a result, the desolvation energy barrier decreases by approximately 21% (from 39.69 to 31.25 kJ·mol-1). The zinc-bromine battery with dual-site interface delivers a high specific capacity exceeding 293.8 mAh·g-1 at 0.2 A·g-1, which reaches approximately 87.5% of the theoretical capacity of pure bromine (335.5 mAh·g-1).

Conjugated polymers, especially the donor-acceptor alternating ones, have been termed as good candidates in phototherapy, since their strong light-harvesting ability and increased intersystem crossing channels from singlet to triplet states could improve the reactive oxygen species (ROS) generation efficiency. Such alternating conjugated polymers are usually prepared though Stille or Suzuki cross-coupling polymerization between two types monomers of donor and acceptor, which in fact usually results in homocoupling defect of donor-donor or acceptor-acceptor structures in obtained polymers. In this contribution, we prepared a series of donor-acceptor-type alternating conjugated polymers photosensitizers through different polymerization processes, and found that all the polymers prepared by direct arylation coupling polymerization (DArP) showed much better ROS generation efficiencies and fluorescence intensities than their similar analogues prepared by Suzuki polymerization. Detailed mechanism studies confirmed that the donor-donor or acceptor-acceptor defects could decrease the exciton lifetimes of the donor-acceptor alternating polymers upon laser irradiation through obstructing exciton diffusion, and the homocoupling-defect-free polymers prepared by DArP therefore demonstrated better performance. In addition, PTD-DArP, constructed by triphenylamine donor and diketopyrrolopyrrole acceptor, demonstrated much better biodegradation capacity than PTD-Suzuki, and it could also match the 660 nm clinical laser, making it good candidate in phototherapy, which has been further confirmed by both in vitro and in vivo results via two models of tumor and diabetes infection. At last, by using two previously reported high performance conjugated polymer photosensitizers as the models, the universality of our strategy was further verified.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e20477"},"PeriodicalIF":26.8,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147830981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
