The electrochemical performance of the transition metal organometallic compound can be modified by modifying the functional groups on the ligands surrounding the transition metal. In this work, we synthesized the cobalt-iron-hydroxyquinolinate (CFH) through the solvothermal method. The reduced graphene oxide (RGO) is incorporated into the CFH to enhance the electrical conductivity, which improves the electrochemical performance. The cobalt-iron-hydroxyquinolinate incorporated RGO (CFHR) was electrochemically evaluated by the cyclic voltammetry, charge-discharge analysis, electrochemical impedance spectroscopy analysis, and distribution relaxation time analysis (DRT). It shows the higher specific capacity of CFHR (1076 mF cm-2) than CFH (631 mF cm-2) by adding RGO to the CFH at 1 mA cm-2. The diffusion coefficient is calculated from the EIS analysis. Dunn's analysis was used to study the capacitive and diffusive contributions of the CFH and CFHR. The DRT analysis elaborates the mechanism involved in the electrochemical process. The systematic electrochemical analysis resulted in the CFHR can be a good electrode material for the hybrid supercapacitor applications.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"91 4","pages":"e202500706"},"PeriodicalIF":2.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147687300","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}

Markedly, this method not only eliminates the need for hazardous solvents and expensive catalysts but also works under operationally mild and eco-friendly conditions while affording the anticipated products in good-to-excellent yields. Among the various tested eutectic mixtures, the combination of choline chloride (ChCl) with N, N'-dimethylurea (DMU) showed the best efficiency and reproducibility with aldehydic partners while reacting with 1,8-diaminonapthalene. On the other front, a melt of the DMU and L-(+)-tartaric acid afforded worthy results between ketones and 1,8-diaminonapthalene. Pleasingly, by using this DESs-mediated green methodology, we have assembled a variety of useful functionalized perimidines including four bioactive molecules (5b-e) and an anionic sensor (5a). Thus, the prepared perimidines were characterized by means of standard nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry. The melting points for all compounds besides the IR spectral data for the novel molecules have also been revealed. Additionally, the structures of two novel derivatives (9e-f) were unequivocally ascertained using single crystal X-ray diffraction analysis. Herewith, we have also reported the preliminary absorption (λmax at 234 nm) and emission properties of the synthesized compounds. Remarkably, this method was applied to a large-scale synthesis besides the catalytic efficiency was also checked thrice without much loss in the product yield-making this method attractive from the industrial perspective.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"91 4","pages":"e202500648"},"PeriodicalIF":2.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147687280","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}

In this work, a flexible composite solid polymer electrolyte (CSPE) was developed using MOF-199 and the natural biopolymer phytagel, with NaCl as the Na+ source and glycerol as a plasticizer to enhance ionic mobility. Fourier transform infrared confirmed chemical interactions within the composite, while PXRD verified its crystallinity and structural integrity. Field-emission scanning electron microscopy images showed a uniform dispersion of metal-organic framework particles throughout the polymer matrix. The optimized CSPE achieved an ionic conductivity of 2.31 × 10-4 S cm-1 at room temperature. Electrochemical testing demonstrated excellent performance: cyclic voltammetry yielded specific capacitances of 139 F g-1 at 1 mV s-1 and 69 F g-1 at 5 mV s-1, indicating efficient ion transport and charge storage. Galvanostatic charge-discharge measurements further confirmed a stable capacitance of 38 F g-1 at 0.1 A g-1. The CSPE also exhibited good cycling durability, maintaining ∼89% coulombic efficiency over 1000 cycles, with a low equivalent series resistance (∼70 Ω) even at the final cycle. Overall, these findings highlight the CSPE as a promising, eco-friendly, and scalable electrolyte platform for next-generation energy storage technologies, including batteries, supercapacitors, and fuel cells.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"91 4","pages":"e202500739"},"PeriodicalIF":2.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147715385","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}

No O-(thionic) ester was formed. For this, we wished to clarify the confusion regarding the outcome of such alkylations described in the literature. A few analogous derivatives were also synthesized and characterized for comparison. First in the literature, crystal structures of two thiolic esters were analyzed in detail. The alkylation led to non-centrosymmetric crystal structures. Moreover, the two isostructural thiolic compounds formed chiral crystals, a rather unusual feature of achiral molecules. Weak interactions such as C-H … O bridges and dispersion dominate and tailor the structure of the crystals. As regards the mechanism, three possible pathways were investigated at the B3LYP/6-31G(d,p)/PCM[toluene] level of theory. The activation enthalpy for the rate-determining step was significantly lower for the triethylamine-catalyzed route than for the base-free variation. Moreover, in the base-catalyzed protocol, the difference of 30.8 kJ mol-1 between the enthalpy of activation for the S and O-alkylations justified the S-selectivity. The pathway involving the anion from the thiophosphinic acid was found unfavorable and hence was excluded.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"91 4","pages":"e70142"},"PeriodicalIF":2.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13084976/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147687285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While SCNE has advanced applications in cytoprotection and cell-surface engineering, its full potential remains constrained by the absence of a unifying conceptual framework. In this Concept report, we introduce the term \"metacells\" to define a new class of engineered, living cell-in-shell systems endowed with dynamic functionality, environmental responsiveness, and programmable behavior. We propose that metacells are characterized by three core functional hallmarks-reconfigurability, loadability, and motility-which collectively distinguish them from conventional SCNE platforms. Through selected examples, we illustrate how these features enable metacells to sense and respond to external stimuli, carry and release functional payloads, and exhibit guided or autonomous motion. By establishing a foundational definition and organizing framework for metacells, this report provides a roadmap for future research at the intersection of materials science, synthetic biology, and cellular engineering, with implications for advanced therapeutics, microscale robotics, and interactive biohybrid systems.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"91 4","pages":"e202500586"},"PeriodicalIF":2.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13090806/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147715401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
