Crystallographic studies show that in the molecules of compounds 1 and 3, an intramolecular proton transfer O-···H-N+ occurs between the hydroxyl group and the azomethine N-atom, resulting in both compounds adopting a zwitterionic imine form. In contrast, in compound 2, an intramolecular O-H···N hydrogen bond is present, stabilizing this compound in the enol-imine form. A Cambridge Structural Database database survey shows that for both tautomeric forms, there are relationships between the geometric parameters characterizing the hydroxyl and azomethine groups. An analysis of intermolecular interactions in the crystals of the title compounds indicates that the carboxyl and hydroxyl groups can form various supramolecular synthons, depending on the position of the carboxyl group in the aromatic ring, which have different interaction energies. This leads to distinct molecular packing patterns within crystal lattices of title compounds and influences their thermal stability.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e2500309"},"PeriodicalIF":3.0,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144625098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These analogues were synthesized via one-pot reaction of TDHPM-5-carboxanilides with dimethyl acetylenedicarboxylate in methanol as a reusable green solvent at room temperature. Two new C(sp2)-N, C(sp2)-S sigma bonds, and one new C-N π-bond were formed during this transformation, achieving yields of up to 99%. This protocol demonstrates a low E-factor (0.09 to 0.35), high atom economy (94.83%), and carbon efficiency (142.68%), reflecting a significant advancement in green chemistry. Compound 3a was synthesized in 99% yield on a gram scale. Compound 3p proved to be an excellent fluorescent probe for Cd2+ ions, showing a nine-fold increase in fluorescence intensity. The limit of detection (LOD) and limit of quantification (LOQ) for 3p with Cd2+ ions were 7.5 μM and 25 μM, respectively, with an R2 value of 0.9903. DFT calculations revealed that Cd2+ ions bind effectively in the cavity of 3p through a ligand-to-metal charge transfer mechanism.

Cadmium sulfide (CdS), as a typical semiconductor-based photocatalyst, has attracted much attention in various coupled reactions of organic oxidation and hydrogen production due to their suitable band gap (~2.4 eV) and well-matched energy band edge positions. This review summarizes the fundamental principles of CdS-based catalysts in light-driven organic oxidation coupled with hydrogen production. On this basis, the review provides a detailed discussion of the key advancements in CdS-based photocatalysts in coupling reactions for hydrogen production and organic conversion, including organic conversion, organic coupling, and organic degradation. Through the synergistic effect of photoexcited electrons driving proton reduction to produce hydrogen and holes leading the directed oxidation of organic substrates, the solar energy utilization efficiency is significantly enhanced. Finally, the challenges and future prospects of CdS-based catalysts for coupling light-driven organic synthesis with hydrogen production are also presented.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500382"},"PeriodicalIF":3.0,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although traditional electrolyte engineering strategies employ oxidation-resistant substances like fluorinated compounds or ionic liquids to optimize the high-voltage performance of supercapacitor, they fail to effectively suppress the aggressive AN interfacial decomposition. Herein, we introduce ethylene carbonate (EC) into AN-based electrolyte (AN-EC electrolyte), significantly enhancing the systematic electrochemical stability. Theoretical calculations and experimental characterizations reveal that EC molecules, with superior electrochemical stability, preferentially adsorb onto electrode interfaces and simultaneously reduce AN diffusion rates through strong intermolecular interactions, leading to the suppression of AN-electrode contact and associated decomposition risks. Benefiting from this dual-protective mechanism, the supercapacitor based on AN-EC electrolyte achieves a high voltage window of 3.2 V, enhanced cycling stability (70% capacity retention after 30,000 cycles at 3.2 V), and superior energy & power densities (33.3 W h kg-1@749 W kg-1 and 17.6 W h kg-1@9,883 W kg-1, respectively).

After a few years, some spots and stains have appeared on the greenish areas of the panels. The common factor was that the panels were produced using the same green enamel. The present work reports on the studies of the observed alterations on green enamels to propose possible degradation mechanisms. These studies are based on using different analytical techniques such as optical microscopy (OM), scanning electron microscopy - energy dispersive X-ray spectroscopy (SEM-EDS), inductively coupled plasma mass spectrometry (ICP-MS), laser-induced breakdown spectroscopy (LIBS), X-ray diffraction (XRD), µ-Raman spectroscopy and UV-Vis-IR spectroscopy. The characterization of the fragments from the original panels showed that a brown layer of dark lead compounds was formed on the green enamel. The alteration occurred in a 3-step alteration mechanism divided into Pb2+ lixiviation from the enamel, formation of hydrocerussite (2PbCO3·Pb(OH)2) and transformation into scrutinyite (α-PbO2) and plattnerite (β-PbO2).","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500205"},"PeriodicalIF":3.0,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144558621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Theoretically, mixing more than one component in solution can lead to different architectures, such as narcissistic, social, blocky, and random. However, controlling the formation of a specific copolymer structure during supramolecular copolymerization remains elusive, owing to the dynamic and reversible nature of non-covalent interactions between the constituent monomers, which facilitate rapid monomer exchange and reorganization in solution. Recent breakthroughs in the synthesis of supramolecular polymers have provided detailed mechanistic insights into supramolecular polymerization, enabling precise control over the size and morphology of the resulting assemblies. Leveraging these mechanistic insights, several attempts have been made to control supramolecular copolymerization. Rational molecular design strategies have been employed to achieve the exclusive synthesis of social and narcissistic copolymers. Conversely, tuning the subtle interplay between homo- and hetero-recognition of structurally matched monomers enabled the selective formation of block copolymers. In this review, we provide an overview of rational design principles and synthetic strategies enabling the precision synthesis of supramolecular copolymers.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500409"},"PeriodicalIF":3.0,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144551510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
