While historically requiring high synthesis temperatures, some solution-processed routes have recently emerged for synthesizing chalcogenide perovskites, such as BaZrS3 and BaHfS3, at temperatures below 600 °C. This study discusses several experimental challenges associated with the moderate-temperature synthesis of solution-deposited chalcogenide perovskites. Firstly, we identify Ruddlesden–Popper (RP) phases as thermodynamically stable competing secondary phases in perovskite synthesis. High sulfur pressures favor the formation of BaZrS3 or BaHfS3, whereas lower sulfur pressures result in a mixture of perovskite and RP phases. Additionally, we briefly discuss the mechanism of moderate-temperature synthesis of chalcogenide perovskites, including some of the morphological and optoelectronic challenges it presents, such as grain overgrowth, secondary phase contamination entrapment, and the presence of mid-band gap emissions. Finally, we address the importance of substrate selection and the potential presence of Ca- and Na-based impurities originating from cation out-diffusion from glass substrates. Addressing these challenges will be crucial as these unique materials continue to be investigated for applications in optoelectronic devices.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 20","pages":" 3358-3372"},"PeriodicalIF":6.0,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/qm/d4qm00441h?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142202558","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}

Herein, we report a new family of symmetrical dibenzothieno and dibenzothieno[2,3-d]thieno[a]-fused BODIPYs (5a–c and 8a–c) synthesized via a simple four-step route involving regioselective 1,7-bromination to selectively enhance the reactivity specifically at the 1,7 positions.

The symmetrical [a]-fusion of dibenzothieno and dibenzothieno[2,3-d]thieno rings results in NIR absorption and emission with high fluorescence quantum yields (ΦF > 0.8), and effectively narrows the HOMO–LUMO gap by elevating the energy level of the HOMO. The high fluorescence quantum yields and tunable HOMO levels of these aromatic heterocyclic [a]-fused BODIPY dyes make them highly promising as functional chromophores, particularly in the field of bioimaging.

This study outlines in detail the design, synthesis and stimuli-responsive properties of two pure single-component organic RTP molecules (DBF-dAc and DBF-dPh) with rigid chemical structures. Molecular dynamics simulations indicated that these molecules might serve as efficient low-molecular-weight organogelators. The presence of multiple carbonyl groups and aromatic rings in the DBF-dAc and DBF-dPh structures likely promoted intersystem crossing, imparting them phosphorescent properties in the rigid gel state. The experimental results confirmed that DBF-dAc and DBF-dPh were capable of forming stable gels in a mixture of DMSO/H2O, facilitated by balanced intermolecular π–π interactions. In the gel state, both DBF-dAc and DBF-dPh formed nanoneedle structures of approximately 100 μm in length. Remarkably, the DBF-dPh gel demonstrated exceptionally long-lived room-temperature phosphorescence (lifetime of 35.2 ms). In addition, the DBF-dPh gel possessed multi-level anti-counterfeiting capabilities responsive to phosphorescence lifetime, UV light, and thermal stimuli. The successful development of the single-component phosphorescent DBF-dPh gel provides crucial insights and guidance for future initiatives, including the theoretical screening of organogelators and the design of multi-level stimuli-responsive RTP materials for dynamic anti-counterfeiting.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 21","pages":" 3577-3586"},"PeriodicalIF":6.0,"publicationDate":"2024-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142202669","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 sluggish kinetics and high oxidation potential of NiII → NiIII severely limit the activity of Ni-based catalysts in the electrochemical UOR. Herein, composition regulation was adopted to enhance the electrocatalytic activity of a nickel-benzene dicarboxylate framework (Ni-BDC MOF)-derived electrode towards urea oxidation. In 1 M KOH with 0.33 M urea solution, the derived amorphous tri-metallic hydroxide layer on the surface of the NiMnCo MOF, induced by electro-activation, exhibited a low onset potential and a steeply rising current density with increasing applied potential. It achieved a benchmark current density of 10/100 mA cm−2 at an anode potential of 1.28/1.33 V vs. RHE, respectively. In particular, a 500 mA cm−2 current density was reached at an impressively low potential of 1.41 V vs. RHE. This exceptional performance is ascribed to the fact that the open framework provides a large electrochemical active surface, while the multicomponent synergy decreases the NiII → NiIII oxidation potential, enhances electron transfer and promotes the UOR kinetics. This study suggests that rational composition regulation is a promising approach to improving the performance of Ni-based MOF materials towards electrocatalytic urea oxidation.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 20","pages":" 3272-3279"},"PeriodicalIF":6.0,"publicationDate":"2024-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142202647","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}

Using solid-state nuclear magnetic resonance (ssNMR), powder X-ray diffraction (PXRD), and UV-Vis/fluorescence spectroscopy, we demonstrated that AC-TFTA displays sharper photophysical changes than its analog AC-PFBA, attributable to differences in the energies of their non-covalent interactions. Furthermore, the reversibility of the amorphous phase in both cocrystals was explored.
