However, the widely employed organic hole transport layers (HTLs) in PeLEDs suffer from inherent drawbacks, such as thermal instability and low carrier mobility, which severely constrain their commercial viability. Although inorganic HTLs offer a robust solution, a systematic framework linking their physicochemical properties to interfacial dynamics is lacking. This review critically assesses the state-of-the-art inorganic HTLs, comprehensively categorizing them into copper-based compounds, nickel oxides, transition metal oxides, and emerging candidates. Beyond material categorization, we dissect the critical interface regulation mechanisms essential for high-performance devices. These specifically involve mitigating interfacial carrier accumulation to suppress non-radiative recombination, leveraging HTLs as growth templates to modulate perovskite crystallization kinetics, and immobilizing metal ions to inhibit detrimental migration. By elucidating these physicochemical interactions, we provide theoretical insights and design guidelines for engineering stable, high-efficiency inorganic HTLs for PeLEDs.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 20","pages":" 8442-8456"},"PeriodicalIF":5.1,"publicationDate":"2026-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148039712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast to polycrystalline thin films that currently dominate high-efficiency device development, single-crystal perovskites, characterized by their grain-boundary-free bulk structure, exhibit a potential ability superior to polycrystalline perovskites. This review summarizes key advancements in the field, hinging on the successful synthesis of micron-thick single-crystal sheets via several preparation techniques such as the Bridgman growth method. Through evolution from the initial MAPbI3 system to mixed-cation compositions (e.g., FA0.95Cs0.05PbI3), coupled with interface engineering and surface passivation strategies, the power conversion efficiency (PCE) of PSSCs has achieved a remarkable leap from single digits to a record 25.8%, accompanied by enhanced operational stability. However, to realize their commercial viability, several critical challenges must be addressed. As we illustrated in this review, further challenges, for instance, reducing the crystal thickness to below 10 micrometers, ensuring robust mechanical and electrical contact between the single crystal and charge transport layers, and developing scalable fabrication techniques for large-area and uniform single crystals, are worthy of further investigations. Despite these hurdles, the considerable potential demonstrated by PSSCs lays a solid foundation for their emergence as a next-generation photovoltaic technology boasting both high performance and exceptional durability.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 23","pages":" 9901-9922"},"PeriodicalIF":5.1,"publicationDate":"2026-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148261435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The application of these films includes fabrication of memory devices, solar cells, photodetectors, light-emitting diodes (LEDs), light amplification by stimulated emission of radiation (LASER), solid-state sensors, etc. A wide range of functional materials, such as pure metals, metal oxides, transition metal dichalcogenides (TMDCs), their alloys, nanocomposites, nanohybrids and heterostructures, can be deposited with precise control over film thickness, composition, and morphology by PVD. This review explores PVD methods for fabricating thin films tailored for gas sensing applications. It highlights how controlled deposition parameters influence sensor performance metrics such as sensitivity, selectivity, response/recovery times, and stability. Various transduction principles, like resistive, capacitive, optical, acoustic, etc., have been covered to explain and highlight the role of quality films produced by PVD techniques for gas sensing. This review provides an overview of the critical role, challenges, and promising future of PVD in depositing innovative gas-sensing materials and tuning their electrical properties for improved sensing behaviour.

Common methods for detection of Tv include the use of rheology and dynamic mechanical analysis under external force, but external force may affect Tv. Herein, a visual detection method for Tv is proposed based on fluorescein-soaked photonic coatings from lower photonic crystals (PCs) and upper vitrimers. Because PCs have photonic band gaps (or structural colors), by combining different structural colors of PCs and the fluorescence of vitrimers soaked with fluorescein, when the heating temperature is higher than Tv of the vitrimer, the ester (or carboxyl) group of fluorescein undergoes ester exchange with the ester group in vitrimers, and the color and fluorescence intensity of photonic coatings show great changes. Tv of vitrimers is easily obtained according to these obvious changes and it is unaffected by the use of a different fluorescein. Accurate fluorescence spectra can be measured to further identify the Tv of vitrimers. The lower PCs enhance the sensitivity of Tv detection for vitrimers. The visual detection method is simple, non-damaging, and accurate, has good reliability and universality, and does not require expensive equipment.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 23","pages":" 9932-9942"},"PeriodicalIF":5.1,"publicationDate":"2026-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148261437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the limited mechanical strength of PDMS itself and its poor self-healing properties after prolonged use restrict its application in flexible sensors. Here, we propose a novel approach to successfully prepare a self-healing polydimethylsiloxane material (Si-DOPAx-Fey) with enhanced mechanical properties by introducing a metallic coordination network. The obtained Si-DOPAx-Fey exhibited a maximum tensile strength of 652 kPa and an elongation at break of 133%. When fracture damage occurred, Si-DOPA3-Fe0.6 achieved a self-healing efficiency of 90.3% after 8 hours of repair at room temperature. Based on Si-DOPA3-Fe0.6, we combined it with AgNWs to prepare Si-DOPA3-Fe0.6-AgNWs for measuring human physiological activity in real time. According to experimental results, Si-DOPA3-Fe0.6-AgNWs had a sensitivity of 4.6 and a linear response coefficient R2 of 0.999 within the 0–60% strain range, indicating good stability and sensitivity for this flexible sensor.

Endowed with advantages such as high energy conversion efficiency, low energy consumption, and excellent functional expandability, they have been successfully applied in intelligent fields including architectural smart windows, electric vehicles, and space shuttles. Among them, polymer-based electrochromic materials have become a key research and development focus because of their rich color-changing varieties, fast color switching, and feasibility of roll-to-roll processing. According to their color-changing characteristics, polymer-based electrochromic materials are mainly classified into two categories: “colored to other colors (including colorless)” and “colorless to other colors”. These two types of materials not only show distinct contrasts in color-changing features but also form a perfect complementary relationship in practical applications. The “colorless to other colors” electrochromic polymers, as new types of materials that have developed rapidly in the past 20 years, possess significant scientific research interest and practical application value. However, up to now, there has been a lack of detailed analysis and reports on the design, development, and research progress of such materials. Therefore, this review will sort out and introduce the development status of these materials from the perspective of the structure–property relationship between material structure and electrochromic characteristics, summarize the strategies for designing and developing such polymer materials, and discuss the future development trends of these materials.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 20","pages":" 8394-8441"},"PeriodicalIF":5.1,"publicationDate":"2026-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148039711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The obtained sample exhibits a uniform porous spherical architecture with an ultrathin N-doped carbon shell, thereby effectively buffering the volumetric strain of CoSe2 and accelerating the electron/ion transport kinetics. Specifically, the CoSe2@NC anode delivers a high initial discharge specific capacity of 513.7 mAh g−1 and retains 431.3 mAh g−1 after 100 cycles, demonstrating excellent capacity retention.
