A comparative assessment of solution-based crystallization and mechanochemical synthesis via liquid-assisted grinding provides insight into the viability of different synthetic methodologies. The crystallographic analysis reveals isostructurality among the three cocrystals, with lattice stability being modulated by the increasing atomic radius of the halogen substituent. Complementary techniques, including thermogravimetry, differential scanning calorimetry, Fourier transform infrared spectroscopy, and Hirshfeld surface analysis, further elucidate the intermolecular forces driving the formation of these crystalline phases.

Functionalization modifies the carbon structure, introducing nanowindows or causing wall degradation, altering conductivity and surface chemistry without significantly affecting particle size. Catalysts synthesized by the polyol method are characterized structurally, texturally, and electrochemically. The results demonstrate that Re addition enhances ethanol electrooxidation through synergistic effects with Pt, reducing onset potentials and increasing electrochemically active surface areas, particularly at an optimal Re loading of 3 wt%. Functionalized supports, especially MC-HNO3, further improve catalyst dispersion and electrochemical performance.

Cocrystals of octafluorobenzidine with 18-crown-6 of 1:1 stoichiometry belong to the enantiomorphous space groups P65 and P61. The helical self-assembly of these achiral molecules is achieved due to the interplanar angle of the bis-aryl molecule (≈60°), which is fixed by directed N-H···Ocr H-bonds between two Hamino atoms with two Ocr atoms at both ends of the molecule. Cocrystallization of octafluorobiphenol results in the formation of a crystalline hydrate based on the water-mediated H-bond Ar-O-H···O(H)-H···Ocr. Flexible water linker eliminates the effect of the H-donor coformer structure and makes this cocrystal achiral. The hydrogen bonding details between octafluorobenzidine and 18-crown-6 within a unit cell are investigated through a combination of vibrational spectroscopy and quantum mechanical calculations. An oxygen atom in 18-crown-6 is identified as a chiral center, as a result of intermolecular interactions involving this atom and hydrogen atoms bonded to its α and β carbon atoms. The unique interaction patterns of 18-crown-6 with acetone and chloroform, along with scanning electron microscopic images, reveal the role of solvent molecules in determining the chirality of the self-assembly.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500481"},"PeriodicalIF":2.8,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145063035","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}

However, its application is often limited by the poor solubility of biomass-derived substrates. Herein, this challenge is addressed by synthesizing hydrophilic, electron-rich pyridine-based glycopolymers via reversible addition-fragmentation chain transfer polymerization, followed by deacetylation of glucose- and maltose-based segments. The polymers and CdS nanorods are thoroughly characterized using various spectroscopic and thermal analyses. The resulting deacetylated glycopolymers exhibit enhanced aqueous solubility and are employed as biomass replacement for photoreforming. The as-prepared CdS nanorods with P4VP-b-PMDG significantly improve glucose photoreforming, achieving an efficient hydrogen evolution rate of up to 1685 μ mol h-1 g-1 with an apparent quantum yield of 4.10% under alkaline conditions (10 M NaOH). The CdS nanorods' stability is investigated through a photocatalytic recyclability test, representing a regeneration efficiency of 94.36% in the fourth cycle. This work highlights the potential of tailored hydrophilic polymers to overcome solubility limitations and enhance the efficiency of biomass photoreforming systems.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500401"},"PeriodicalIF":2.8,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145022498","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 technical applications, they are typically used as complex mixtures rather than monodisperse systems. These mixtures often include ionic and non-ionic surfactants, with the non-ionic components comprising various monodisperse species. Such complexity influences adsorption behavior significantly. In this study, we therefore investigated how different monodisperse components within a technical surfactant system affect adsorption kinetics, characterized through dynamic interfacial tension measurements. We focused on blends of the anionic biosurfactant di-rhamnolipid and technical alkyl ethoxylates. Our results show that increasing the di-rhamnolipid ratio enhances the adsorption rate at interfaces logarithmically compared to ethoxylates, which is especially relevant for applications requiring rapid adsorption. Moreover, we observed partitioning effects of the ethoxylates' hydrophobic moieties when comparing adsorption at the oil/water and air/water interfaces. These differences explain why more hydrophilic ethoxylates are often preferred in practice. Overall, our findings deepen the understanding of adsorption behavior in mixed surfactant systems and provide a basis for tailoring formulations by adjusting the component ratio for specific application needs.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500259"},"PeriodicalIF":2.8,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145022516","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}

Receptors 1 and 3 combine an electron-poor aromatic scaffold with a cation-binding crown ether unit. Binding studies monitored by 1H NMR titrations in acetonitrile revealed that these receptors exhibit enhanced affinity for bromide anions in the presence of sodium cations, indicating cooperative ion-pair recognition. Receptor 1, incorporating both nitro-substituted aromatic rings and a macrocyclic cation-binding site, demonstrated the most significant anion-π binding enhancement. In contrast, control receptor 2, lacking electron-withdrawing groups, exhibited negligible anion affinity, supporting the role of π-acidity in anion binding. Quantum chemical calculations and electrostatic potential maps further confirmed the contribution of anion-π interactions in receptor function. The incorporation of amide functionalities in receptors 3 and 4 improved binding affinity, highlighting the synergistic effect of multiple binding domains.

Herein, triblock polymers composed of pyropheophorbide a photosensitizer (PPa), polyethylene glycol, and phospholipid are synthesized. These triblock polymers, driven by hydrophilic-hydrophobic interactions, spontaneously fold into an amphiphilic structure and further self-assemble into nanomicelles. This novel nanomicelle, termed nanoPPa, provides a stable, nonpolar microenvironment for photosensitizer molecules, thereby enhancing photodynamic energy efficiency by minimizing energy loss from molecular collisions and self-aggregation. Compared to the photosensitizer PPa alone, nanoPPa exhibits a remarkable fivefold increase in singlet oxygen generation, accompanied by a substantial boost in phototoxicity. Simultaneously, an increased fluorescence emission is observed. These enhancements in phototoxicity and fluorescence signify the potential of nanoPPa for dual applications in photodynamic therapy (PDT) and photodynamic imaging (PDI). The fabrication of this nanostructure is proposed as a versatile strategy to improve the application of photosensitizers and enhance therapeutic outcomes.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500232"},"PeriodicalIF":2.8,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144999383","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}
