In this study, we have devised and synthesized four types of intramolecular heterojunctions (POM@MOFs), constructed by integrating polyoxometalates (POMs) with metal–organic frameworks (MOFs). Specifically, we utilized an organic linker featuring a photosensitive phenothiazine core with incrementally oxidized sulfur sites, and employed Zn/Cd as the metal nodes to create four analogous POM@MOF composites, designated as <b>SO_x-M</b> (<b>x</b> = 1, 2; <b>M</b> = Zn, Cd). Through strategic heterointerface engineering, we have achieved a synergistic improvement in both the generation and separation efficiency of charge carriers within these materials. Our results demonstrate that the <b>SO₂-M</b> series, which incorporates phenothiazine in a more oxidized state (-SO₂-), surpasses the <b>SO-M</b> series (-SO-) in terms of charge carrier generation and separation efficiency. Furthermore, within the <b>SO₂-Cd</b>, the covalent bonds connecting the MOF and POM components significantly facilitate the separation and migration of photogenerated electrons. This collaborative regulatory mechanism enables <b>SO₂-Cd</b> to exhibit outstanding photocatalytic performance. This research introduces a pioneering approach for the cooperative modulation of oxidation states and heterointerface interactions, offering a promising pathway for the development of highly efficient photocatalysts.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"19 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147736025","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}

An elaborated design of support materials is crucial to address the key issues posed by the low concentration of hydrogen intermediates (^*H) and their weak adsorption on the Pt single atoms in high-valence states. Herein, a cation-π interaction engineering strategy was proposed to immobilize Pt single atoms onto N‑heterocyclic conjugated polymers, generating moderate cation-π interactions that stabilize Pt single atoms in low-valence states with favorably-elevated Pt 5d-band centers for enhanced ^*H adsorption on them. Furthermore, this design can create a favorable local chemical environment with a high ^*H coverage near Pt single atoms owing to the sufficient ^*H supply rate, stemming from the facilitated water dissociation on the N atoms of N‑heterocyclic conjugated polymers. The resulting catalyst with a low Pt loading (1.41 wt.%) achieves a low overpotential of 14 mV at 10 mA cm⁻² and an outstanding stability for 1500 h of continuous operation at 100 mA cm⁻² toward acidic HER catalysis.

In contrast, ordered racemic monolayers induce no notable change, suggesting a critical role of net chiral symmetry in altering the phonon spectrum.

The solidification of electrolytes offers a viable approach to addressing these issues, but is often hindered by insufficient salt dissociation, sluggish Zn²⁺ transport, and unstable Zn-electrolyte interfaces. Herein, a piezoelectric-field-coupled composite solid electrolyte is developed by integrating ZnO into the poly(vinylidene fluoride-hexafluoropropylene) matrix. ZnO synergistically triggers electroactive β-phase enrichment and amplifies polarization, establishing a persistent interfacial electric field. This field-driven regulation facilitates salt dissociation and accelerates Zn²⁺ transport while homogenizing interfacial flux to lower nucleation overpotential and steer Zn deposition toward the thermodynamically stable Zn(002) plane. Simultaneously, the stabilized interface promotes the formation of a thin, continuous solid electrolyte interphase rich in inorganic ZnF₂/ZnS inner layer, which further passivates the anode against parasitic reactions. Consequently, Zn|Zn symmetric cell displays an exceptional lifespan of 2750 h at 0.1 mA cm⁻², with ultra-high critical current density of 7.0 mA cm⁻².

Ada-ICzBN obtains narrowband emission at 526 nm with full width at half maximum (FWHM) of 26 nm in toluene, which could be maintained in highly doped films (16 wt%) due to the 3D steric hindrance of adamantane.

This material uniquely integrates an ultrawide bandgap (≈4.03 eV), high-Z constituents for efficient X-ray attenuation, and a pronounced anisotropic structure. The resulting photodetector exhibits exceptional dual-functional performance. For ultraviolet-B detection, it achieves a high responsivity (0.29 A/W), ultrafast speed (42.4/54 µs).

This phenomenon is harnessed for proof-of-concept demonstrations in dual-wavelength information encoding and image contrast enhancement using a convolutional neural network (Recognition accuracy &gt;97%). Concurrently, the device serves as a high-sensitivity X-ray detector, demonstrating a superior sensitivity of 5.3 × 10⁴ µC Gy_air⁻¹ cm⁻², an ultralow detection limit of 27 nGy_air s⁻¹, and exceptional operational stability, validated by high-resolution biological imaging.

However, the complex ionic environment of seawater-based electrolytes, which leads to chloride pitting corrosion, zinc (Zn) dendrite growth, and hydrogen evolution reactions (HER), impedes their practical applications. Herein, we design a multi-functional binary additive electrolyte incorporating carboxymethyl cellulose (CMC) and magnesium sulphate (MS) into seawater-based electrolytes to tackle these challenges. The addition of CMC with strong Zn/Zn²⁺ affinity can significantly modify the solvation structures within the seawater-based electrolyte and facilitate the reversible deposition behaviour of Zn²⁺ ions. Moreover, the cation-binding properties of CMC²⁻ enable it to effectively induce Mg²⁺ ions and seawater cations toward the Zn anode. Simultaneously, Mg²⁺ ions, possessing the highest charge density among seawater ions, show strong electrostatic forces toward free-water. Thus, it can induce the multiple seawater cations to form a water-poor layer on the Zn anode surface, thereby inhibiting the HER and the corrosion reactions. Notably, the intercalation reactions of multiple cations effectively suppress the structural collapse of cathode materials. Equally important, we innovatively introduced a unidirectional gas valve to resolve gas generation issues of the pouch cell, effectively resolving the key issue of gas accumulation in practical applications. Benefiting from the superior modification effect of the binary additive, the Zn//Zn symmetric cells in seawater-based electrolyte exhibit a long-term stability of over 5197 h at 5 mA cm⁻². Furthermore, the Zn//Cu asymmetric cells possess an average CE of 99.74% over stable cycling for 4000 cycles at 5.0 mA cm⁻². The Zn//NVO full cells retain 150 mAh g⁻¹ after 1000 cycles at 2 A g⁻¹.
