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. This study not only provides an innovative approach for the application of La-doped Ag3PO4 in environmental pollutant catalysis but also reveals a novel internal electron transfer pathway and the underlying mechanism for enhanced photocatalytic activity.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 7","pages":" 1189-1204"},"PeriodicalIF":6.0,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688201","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}

In this work, we explored the specific emission regulation of a dual-ESIPT-active molecule, BDIBD (2,5-bis(4,5-diphenyl-1H-imidazol-2-yl)benzene-1,4-diol), by subtly controlling the ground and excited states through different crystallization conformations. Notably, the crystals obtained in dimethylformamide (BDIBD–DMF) and methanol (BDIBD–MeOH) exhibited a single emission band, corresponding to the green and red emission from the keto1st and keto2nd excited states, respectively, while the crystals obtained in acetone (BDIBD–ACE) displayed dual emissions from both states, resulting in an overall yellow color. A comprehensive theoretical study verified that the modified intermolecular interactions, due to different crystallization conformations, regulated emissions by affecting the energy barrier of dual-ESIPT processes. The above results provide a concrete understanding of the regulation of excited-state emissions through ground-state conformational changes in ESIPT processes, as well as unique insights into the design and application of novel ESIPT emission materials.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 7","pages":" 1181-1188"},"PeriodicalIF":6.0,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/qm/d5qm00012b?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688173","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}

To address these limitations, a number of enzyme mimics, particularly nanozymes, have been widely explored as superior candidates to mimic natural enzymes because of their low cost, high stability, flexibility and controllable catalytic activity. Because of their outstanding physicochemical properties, nanozymes demonstrate widespread applications in disease diagnosis and treatment, antibacterial agents, chemical sensing, and environmental pollutant monitoring and remediation. This review summarizes recent progress in the design and fabrication of nanozyme-based materials and their catalytic mechanisms and application in environmental pollutant detection and remediation.

Various approaches have been explored to enhance the morphology of organic films, and one effective method involves using crystalline templates with large domain sizes to promote the growth of the upper active films. However, strategies for obtaining continuous and uniform template layers over large areas are still in high demand. Herein, we employ a “solution epitaxy” method to fabricate a uniform C32H66 crystalline film as the template layer, facilitating the growth of the organic semiconductor 2,8-difluoro-5,11-bis(triethylsilylethynyl)anthradithiophene (diF-TES-ADT) over a large area. Our results demonstrate that the morphology of the epitaxial films strongly depends on the morphology and thickness of the template layer. By optimizing the template layer, we successfully obtain terraced-like organic semiconductor films with excellent crystallinity with large domain sizes. These epitaxially grown films are then employed as carrier transport channels in OPTs, leading to the development of high-performance devices with a sensitivity of 3.74 × 106 and a responsivity of 6.2 × 103 A W−1. Furthermore, the obtained phototransistors show promising potential for emulating synaptic behavior with their dependence on illumination power intensity and UV light addition time. This finding provides a feasible strategy for obtaining high-quality organic films with efficient charge transport and high photoresponse properties.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 7","pages":" 1174-1180"},"PeriodicalIF":6.0,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688107","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}
