Their compartmentalized structures closely resemble the characteristics of cellular and subcellular systems, enabling the development of biomimetic microreactors that enhance catalytic processes. By enlarging interfacial areas while effectively partitioning reactants into their preferred phases, Pickering emulsion-based microreactors improve kinetic parameters and prevent unwanted interactions. The adaptability of Pickering emulsions is further augmented through modifications to the properties and composition of the particle emulsifiers, rendering them multifunctional and facilitating efficient reactions between immiscible phases, such as oil and water, especially when the emulsifiers themselves act as catalysts. This review summarizes recent advances in Pickering emulsion-based biomimetic microreactors, focusing on the versatile choice of various particles, design principles, and their applications in facilitating biphasic catalysis in a biomimetic way. We also discuss the challenges and future perspectives for further refining these microreactors for enhanced biphasic catalytic processes.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 8","pages":" 1290-1311"},"PeriodicalIF":6.0,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793000","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, achieving precisely organized organic low-dimensional heterostructures is limited by homogeneous nucleation and interface energy mismatch between different molecules. A wrap-around self-assembly strategy is proposed, utilizing multi-faceted alignment to construct interspersed topological organic low-dimensional heterostructures. Interspersed topological heterostructures with precise spatial organization from bottom to top were successfully fabricated by controlling the sequential nucleation and growth of different crystals through stepwise solution self-assembly. Multi-faceted lattice matching promotes effective structural integration between one-dimensional (1D) microgranules and two-dimensional (2D) microsheets with the ultralow lattice mismatch rates η of 0.7% and 0.3%, respectively. Notably, the unique serial arrangement of microrods and microsheets enables photon coupling from 1D to 2D. The dimensional cross-guide coupling process facilitates optical interconnection, leading to more efficient optical signal transmission and processing, thereby enhancing the performance of optical interconnect technologies in information communication and optoelectronic devices.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 8","pages":" 1259-1266"},"PeriodicalIF":6.0,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793004","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}

Usually, plastic deformation can lead to some amount of disruption that can result in new physical phenomena and fascinating structures. However, how to realize efficient plasticization and manipulation to obtain irreversible variation in such materials, especially those presenting quantum material behavior, is a great challenge. Herein, we show that upon plastic deformation induced by supercritical CO2 (SC CO2) on SrZrO3, typically at a pressure of 16 MPa, SrZrO3 experiences a transition from a bulk material to a two-dimensional (2D) structure. More importantly, it can be observed that the octahedral rotation of ZrO6 is suppressed. Furthermore, plastic deformation frequently induces magnetism in SrZrO3. Via polarization characterization, SrZrO3 displays multiferroic characteristics, exhibiting a considerable enhancement in the saturation magnetisation strength and polarization strength. At room temperature, SrZrO3 exhibits a saturated magnetisation of 0.1280 emu g−1, accompanied by a polarization of 0.27 μC cm−2. Therefore, this work demonstrates that plastically deformed SrTiO3 induced by SC CO2 can successfully transition into a quantum multiferroic material. These results establish a new method toward plastic deformation for the manipulation of the electronic properties of quantum materials.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 8","pages":" 1213-1219"},"PeriodicalIF":6.0,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143792987","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}

They have to be dispersed in proper host materials to alleviate these problems, but their electroluminescence (EL) performances are not satisfactory in commonly used host materials without the aid of phosphorescence or TADF sensitizers. Herein, we develop three new host materials by introducing a cyano group on the different positions of the diphenyl moiety of a widely used host 3,3′-di(9H-carbazol-9-yl)-1,1′-biphenyl (mCBP). The generated materials exhibit bipolar charge transport properties, with greatly improved electron-transporting ability relative to mCBP. They can serve as efficient host materials for a series of MR-TADF emitters, providing significantly enhanced EL efficiencies and elongated operational lifetimes than mCBP. The MR-TADF emitters in these new host materials can have higher photoluminescence efficiencies, accounting for the improved EL performances and device stability. These results reveal that the exploration of bipolar host materials could be a promising alternative to maximize EL performance of MR-TADF materials without employing sensitizers.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 8","pages":" 1220-1227"},"PeriodicalIF":6.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143792999","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 this study, La3+ ions were introduced into Ag3PO4via an in situ co-precipitation method, forming p-type doped LaxAg3−xPO4 without altering the original cubic morphology of Ag3PO4. The introduction of La3+ led to a reduction in the band gap, an expansion of the light absorption range, and an increase in electron localization. Density functional theory (DFT) calculations revealed that La doping introduces new states within the band gap, facilitating energy transitions and altering the electronic structure. Time-dependent DFT (TDDFT) calculations confirmed that the introduction of La3+ enables photoexcited electrons to predominantly migrate from Ag 4d and O 2p orbitals to La 4d and P 2p orbitals. This key finding unveiled the anti-photocorrosion mechanism of LaxAg3−xPO4. Free radical capture experiments and electron paramagnetic resonance (EPR) analysis demonstrated that La doping enhances the electron migration efficiency in LaxAg3−xPO4, promoting the conversion of ˙O2− to ˙OH radicals.

Current industrial processes integrating solar energy with fossil fuels for large-scale chemical production remain hindered by several challenges, including dynamic catalytic site restructuring that alters product selectivity and progressive catalyst deactivation that compromises economic viability. Therefore, a reasonable structural design could enormously enhance the mass and energy transfer during catalytic reactions. Considering the complexity of the reaction micro-environment, catalytic site reconstruction plays a crucial role in dynamic photothermal catalysis. Taking into account the spatial and temporal reaction processes, this review is focused on the latest progress of the catalytic sites confined to different three-dimensional (3D) structures. Initially, we provide an introduction to the mechanism of photothermal reaction on 3D structures, focusing on the mass and energy transferring pathways and the corresponding reactions. Subsequently, several typical distribution types of the catalytic sites are discussed, emphasizing that various 3D configurations modified with different types of catalytic sites would drive different reactions, including the biological enzyme site interaction process. We further elucidate the dynamic reconstruction of active sites under varying microenvironmental conditions, primarily induced by small-molecule adsorption and weak interfacial fields. Moreover, the applications of photothermal 3D materials are discussed under realistic reaction conditions, opening a new window for filling the gap between micro-structure and macro-process in catalysis. Finally, we briefly summarized the future challenges in solar-assisted catalytic engineering.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 8","pages":" 1312-1329"},"PeriodicalIF":6.0,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793028","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}

These ICs exhibit photoactivated delayed phosphorescence (PH) from the excited triplet state (T1), which is called prolonged irradiation-induced delayed luminescence (PIDL), after a few minutes of induction time, during which only fluorescence is observed. This result is because oxygen quenching efficiency gradually weakens as the ground-state oxygen decreases via energy transfer from the ICs in the T1 state. As compared with the ICs containing ether linkages (OD-IC, BO-IC), the PHs of the ICs containing thioether linkages (SD-IC and BS-IC) were significantly enhanced by the heavy atom effect, and these showed bathochromic (red) shifts of the PL peaks owing to the extended π-conjugation. Furthermore, the ICs containing five-membered cores (BO-IC and BS-IC) demonstrated longer PIDL lifetimes and shorter induction times than those of the ICs containing flexible linkages (OD-IC and SD-IC), owing to their structural rigidity. In particular, BS-IC exhibited an excellent PIDL properties such as the largest intensity (I = 2480), a long lifetime (τPIDL = 410 ms), and a short induction time (tID = 1.55 min) owing to the rigid core containing a sulfur atom. Based on the results, this study provides a valuable strategy for developing novel PIDL materials.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 7","pages":" 1139-1148"},"PeriodicalIF":6.0,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/qm/d4qm00871e?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
