Toward this end, 3-hydroxy-2-methylpyridin-4(1H)-one (H), imidazole-4-carboxylate (K), purine-6-carboxylate (P), and 7-deaza-6-pyrazolylpurine (D) were used as artificial metal-binding nucleobases. Cyclic voltammetry and square-wave voltammetry confirmed the immobilization of suitably modified oligonucleotides on Au electrodes. The incorporation of the metal ions into the base mismatches to form metal-mediated base pairs showed a negligible effect on the peak potentials. Ambiguous electrochemical impedance spectroscopy results were obtained for DNA with metal-mediated base pairs, as some duplexes showed no effect of metal ion addition, while others showed variable charge transfer resistance (RCT) with no discernible pattern. Notably, the formation of AgI-mediated base pairs induced larger relative changes in RCT compared to CuII-mediated base pairs. Amongst the latter, only strands containing the artificial nucleobase H showed statistically relevant sequence- and distance-dependent charge transfer changes upon metalation. The data indicate that neither nucleobase charge nor nucleobase size directly correlates with the charge transfer resistance, but suggest that changes in DNA film stiffness and hence permeability outweigh other effects.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500494"},"PeriodicalIF":2.8,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145249083","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}

Porous solid matrices are promising candidates for this purpose, due to their high surface areas and pore volumes. Herein, two coconut shell-derived activated carbons (AC) (CS-CO2 and CS-ZnCl2), obtained through physical and chemical activation, are evaluated and compared with two commercial adsorbents: an AC monolith (ACM) and a metal-organic framework. The adsorption capacities for SF6 and nitrogen (N2) are measured gravimetrically at three temperatures: 283.15, 303.15, and 323.15 K. The experimental data are fitted using the Toth model, and the impact of temperature and pressure on the adsorption performance is analyzed. The order of SF6 adsorption capacity is: ACM > CS-ZnCl2 > Fe-BTC > CS-CO2, reflecting dependence on surface area. Selectivity for SF6/N2 separation is evaluated using Ideal Adsorbed Solution Theory, with ACM exhibiting the highest adsorption capacity due to its selective separation properties. These findings contribute to the understanding and selection of efficient adsorbent materials for SF6 separation and recovery, providing valuable insights for their future implementation in industrial gas treatment and environmental management applications.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500376"},"PeriodicalIF":2.8,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145249067","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 new method to study the reaction intermediates of carbon dioxide reduction reaction (CO2RR) and hydrogen elimination reaction (HER) catalyzed by Cobalt(III) catalysts with high photocatalytic activity in a water/acetonitrile solvent system is proposed. The optimization of the cobalt catalysts ([Co(acac)(bpy)(N3)2].H2O 1, [Co(acac)(en)(N3)2] 2 and [Co(acac)(2-pic)(N3)2] 3) for photocatalytic activities in visible light irradiation (>420 nm) is performed by varying solvents systems (v/v) (CH3COCH3/H2O, CH3CN/H2O, DMF/H2O, EtOH/H2O and H2O), sacrificial electron donors (1-benzyl-1,4-dihydronicotinamide (BNAH), diethanolamine (DEOA), triethylamine (TEA), and triethanolamine (TEOA), photosensitizers (Eosin Y, Erythrosin B, Fluorescein (Fl), Rose Bengal, Rhodamine-B, and Ru(bpy)3 (Ru)), pH (7-12.5) and different catalyst concentrations (0-2 mM). The arrangement around the Cobalt(III) ion is an octahedral coordination geometry. A combination of experimental characterization and density functional theory (DFT) is used to identify the mechanism of the photocatalytic CO2 reduction reaction. DFT calculations and experimental results for the photocatalytic activity of the catalysts 1-3 reveal the involvement of multi-electron metal-ligand exchange coupling in promoting CO2RR and HER, and provide a starting point for the integration of these strategies into catalyst design.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500305"},"PeriodicalIF":2.8,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230953","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}

This interest is attributable to their reversible fluorescence switching behavior, driven by aggregated structural changes associated with phase transitions upon heating and cooling. The research group has developed various PLLCs by incorporating fluorescent π-conjugated mesogens into donor-π-acceptor (D-π-A)-type fluorinated tolanes, functionalized with a range of electron-donating and electron-withdrawing groups (EWGs) at the molecular terminal positions. This article introduces a novel class of D-π-A-type fluorinated tolanes featuring an imidazole ring, which functions as an EWG with both steric and electronic effects. These compounds exhibit distinct phase transition behaviors and photophysical properties depending on the chain length of the flexible alkoxy units. Furthermore, for compounds exhibiting any LC phase, the PL behavior in the mesophase is evaluated. The results reveal that phase transitions lead to changes in both the fluorescence wavelength and intensity. These findings demonstrate that nitrogen-containing heterocycles, such as imidazole, are effective EWG units with both steric and electronic contributions. As such, they hold promise for the design of PLLCs for use in PL sensing materials.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500438"},"PeriodicalIF":2.8,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224725","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}

Representative self-doping groups such as amines, ammonium salts, and other anionic species are introduced and classified. The effects of doping group connecting site selection, including the imide position, aromatic core, and side substitutes, on molecular and electronic properties are then discussed. The application of self-doped PDI/NDI materials in organic electronic devices is also highlighted, covering thin-film solar cells, organic field-effect transistors, and organic thermoelectrics. These materials have shown the ability to improve charge injection, enhance device stability, and regulate interfacial processes. Overall, self-doping is a promising strategy for developing high-performance n-type organic semiconductors. With ongoing improvements in molecular design and device engineering, self-doped PDI/NDI materials are expected to contribute significantly to the advancement of next-generation electronic materials and devices.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500301"},"PeriodicalIF":2.8,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129753","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}
