However, realizing tunable multicolor emission in single-component materials remains a formidable challenge, particularly when aiming for reproducible and structurally consistent performance. Here, we realized adjustable multicolor emission ranging from blue to cool white and finally warm white light in homophthalic anhydride (HA) crystals through pressure treatment engineering. Detailed structural analyses and theoretical calculations reveal that pressure treatment engineering shortens intermolecular nonbonded interaction distances, enhances orbital coupling, and induces the formation of long-range coupled molecular orbitals. This effect not only enables dimer-based charge transfer (CT) transitions but also modulates the oscillator strengths of multiple CT states, thereby enabling precise control over the photoluminescence (PL) color of HA crystals. This work not only highlights the potential of commercial HA crystals as stimuli-responsive multicolor emitters but also provides new insights for designing smart luminescent materials with multicolor and controllable properties.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e00027"},"PeriodicalIF":3.7,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146206233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their flexible valence states, strong chemical polarity, and tunable local structures enable robust polysulfide adsorption and accelerated sulfur redox kinetics. This review provides a systematic overview of V-based electrocatalysts, including oxides, sulfides, nitrides, carbides, borides, metal-organic frameworks, and single-atom configurations, and establishes activity-structure relationships that link their electronic structures, coordination chemistry, and surface properties to catalytic function. Key strategies for performance regulation, such as heteroatom modulation, defect engineering, ligand-filed manipulation, and hybridization with conductive hosts, are summarized to elucidate effective design principles for enhancing intrinsic and practical catalytic activity. Furthermore, remaining challenges and future research directions are outlined, highlighting the opportunities in atomic-level material designs, mechanistic elucidation, and device-level optimizations under practical conditions. Collectively, these insights are expected to advance V-based sulfur electrocatalysis toward practically viable Li─S battery technology and inspire broader innovations in next-generation energy storage and conversion systems.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e03601"},"PeriodicalIF":3.7,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146199590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three pentapeptides (featuring a common self-assembling FFK (phenylalanine-phenylalanine-lysine) motif were synthesized. Two peptides were functionalized with a common N-terminal tetrafluoroiodophenyl (TFIP) moiety as the XB donor, while the C-terminal carried either a phenylalanine or a histidine moiety, to examine the effect of XB. Histidine-functionalized peptide displayed a significant C-I···N XB between its TFIP donor and imidazole acceptor, whereas phenylalanine-terminated analogue showed negligible XB interaction. Despite the presence of XB, histidine-containing peptide exhibited diminished thermal stability and lower self-assembly propensity because of the weaker hydrophobic effect of its imidazole ring as compared to the phenylalanine residue. To probe the halogen effect, iodine atom was substituted with fluorine to generate another control peptide. Comprehensive studies revealed markedly higher stability and enhanced viscoelastic properties of the iodine-containing peptide over its fluorinated analogue, along with distinct self-assembly mechanisms (cooperative vs. isodesmic), which was attributed to the greater hydrophobicity and polarizability of iodine atom compared to fluorine. Overall, the observed stability order highlights a subtle balance among XB, HB, and hydrophobic interactions in fine-tuning peptide self.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e70789"},"PeriodicalIF":3.7,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146218003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Template-assisted synthesis can be employed to construct hierarchical structures in gas-sensing materials, enabling precise multiscale control over morphology, porosity, and intrinsic electronic properties, thereby paving the way for developing next-generation gas sensors with enhanced sensitivity and selectivity. Continuous innovations in the synthesis of hierarchical materials like metal oxide semiconductors (MOS) and metal-organic frameworks (MOFs) have significantly enhanced gas sensing performance in stability, response speed, sensitivity, and selectivity. However, a systematic analysis linking hierarchical structures built via different templating methods to sensing performance remains lacking. This review systematically summarizes the design principles, control mechanisms, and functional applications of three primary templating approaches. Furthermore, this work examines how tailored templating strategies can balance structural precision, synthetic complexity, and environmental impact. Finally, we offer forward-looking perspectives on future development pathways, as well as the challenges and opportunities for practical applications.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e71084"},"PeriodicalIF":3.7,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These aliphatic cations participate in fundamental cellular processes, and their dysregulation has been linked to several cancers and neurodegenerative disorders. Although conventional detection methods, such as chromatography and mass spectrometry, offer excellent sensitivity, their complexity, cost, and limited portability restrict their use in rapid or point-of-care testing. This work presents a colorimetric nanosensor based on gold nanoparticles (AuNPs) functionalized with a p-tert-butyl-calix[5]arene derivative (Calix[5]), a supramolecular receptor with selectivity for primary alkylammonium ions imparted by intracavity host-guest complexation. The molecular recognition event induces interparticle bridging, triggering nanoparticle aggregation that manifests as a visible color change of the suspension. The system exhibits remarkable chain-length-dependent selectivity: long polyammonium chains, such as 1,12-dodecanediammonium and the biogenic polyamine spermine, induce rapid (< 5 min) nanoparticle aggregation, resulting in a distinct plasmonic shift. In contrast, shorter analogues (spermidine, 1,6-hexadiammonium) show negligible responses. These findings demonstrate a simple, rapid, and cost-effective approach for the selective sensing of structurally defined polyamines, with potential applications in noninvasive biomarker monitoring.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e03596"},"PeriodicalIF":3.7,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146218025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite decades of research, all clinical BNCT trials to date have relied exclusively on the legacy agents boronophenylalanine (BPA) and sodium borocaptate (BSH), reflecting historical precedent and regulatory familiarity rather than optimal pharmacological performance. Recent advances in boron chemistry, nanotechnology, and molecular imaging have generated a new generation of boron delivery agents with improved tumor selectivity, multifunctionality, and theranostic potential, yet none have reached clinical translation. This review covers boron carriers reported since 2018, categorized as small molecules, boronated polymers and liposomes, boron-conjugated biomolecules, and imaging-guided or theranostic systems. Trends derived from bibliometric analysis reveal a shift toward nanoparticle-based carriers, which offer modular architectures for simultaneous drug loading, targeting, and imaging. Among these, multifunctional nanoplatforms appear particularly promising for personalized BNCT, where in vivo imaging via PET, MRI, SPECT, or fluorescence can enable patient-specific treatment planning and real-time dosimetry. However, the translation of these innovative agents remains constrained by economic, regulatory, and logistical barriers. The field's next frontier will require harmonized dosimetry protocols, validated imaging standards, and coordinated industrial and academic investment to bridge the gap between chemistry and clinic. BNCT thus stands at a translational gap: sustained interdisciplinary collaboration could finally expand its clinical repertoire beyond BPA and BSH toward a new generation of targeted and image-guided boron therapeutics.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e03533"},"PeriodicalIF":3.7,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13150059/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146197203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
