The electronic effect of substituents has an important influence on the ESIPT process. In this study, we investigated the effects of substituents on the ESIPT mechanism and the photophysical behavior of single-benzene fluorophore (SBF) derivatives with computational chemistry methods. The ω-B97XD/TZVP level of theory was used to calculate bond lengths, interaction energies, infrared spectra, electron-hole analysis, and the energy barriers of ESIPT in SBFs. Our results confirmed the presence of intramolecular hydrogen bonds in both the ground and excited states in SBFs. Transition state calculation demonstrated that increasing the number of electron-withdrawing groups enhances hydrogen bonding interaction and facilitates ESIPT. However, excessive substitution saturates the electron-withdrawing effect, suppresses C═O basicity, and potentially induces conformational constraints, leading to a higher barrier. Our findings provide some important theoretical basis for the design of ESIPT fluorescent dyes.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e70285"},"PeriodicalIF":3.3,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145022423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we developed a simple strategy to synthesize BODIPY-linked NHC metal complexes involving Ag, Cu, Ni, and Pd. The synthesis began with the preparation of BODIPY-imidazolium salt as a precursor ligand. This ligand was used to obtain BODIPY-imidazolium silver carbene complex, which subsequently facilitated the syntheses of BODIPY-linked NHC transition metal complexes (Cu, Ni, and Pd) via the transmetalation method. This approach offers a versatile pathway for the synthesis of various other fluorescent carbene metal complexes. The applications of these BODIPY-linked NHC metal complexes were also explored. Chemotherapeutic anti-cancer activity of BODIPY-imidazolium silver carbene complex showed high cancer cell killing efficacy as compared to its precursor ligand. This outcome confirmed that the attachment of the silver atom is essential to enhance the cytotoxic activities. Additionally, the fluorescence property of the BODIPY moiety is highly useful for cellular imaging, which establishes the silver complex as a potential chemotheranostic agent for cancer management. Furthermore, BODIPY-imidazolium copper carbene complex was explored as a non-noble metal-based catalyst for ammonia borane (AB) hydrolysis to generate hydrogen. This catalytic system was further applied for chemoselective reduction of the aromatic formyl groups in the presence of other reducible functional groups. Overall, this investigation presents a simple and efficient design strategy for the synthesis of different BODIPY-linked metal carbene complexes with potential applications in catalysis, cellular imaging, and cancer therapy.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e00564"},"PeriodicalIF":3.3,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145022444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polysulfone (PSF) and polyvinylpyrrolidone (PVP) were employed as polymer supports for fabricating the SiC-based mixed matrix membrane, which was tested in a dead-end filtration setup. The synthesized SiC and mixed matrix membrane were characterized using SEM-EDX, XPS, TGA, and Raman spectroscopy to evaluate their chemical and physical properties.

This review systematically elucidates the underlying mechanisms and chemistries enabling self-healing behavior, encompassing both extrinsic strategies such as microcapsules, microvascular networks, and corrosion inhibitor reservoirs and intrinsic approaches based on dynamic covalent (e.g., disulfide exchange, Diels-Alder, imine, transesterification/vitrimer networks) and supramolecular interactions (e.g., hydrogen bonding, metal-ligand coordination, ionic, and host-guest systems). Emphasis is placed on recent advances in external stimuli-responsive systems triggered by heat, light, moisture, pH, electricity, or magnetic fields. The performance of these coatings under extreme conditions, including corrosive media, marine environments, thermal cycling, mechanical fatigue, and high-voltage fields, is critically evaluated. Furthermore, this review highlights industrial translation through commercial exemplars (e.g., NANOMYTE® MEND, BASF Elastocoat, Baydur HC, FEYNLAB), scalable fabrication routes (spray coating, dip-coating, UV-curing, and 3D/4D printing), and alignment with sustainability goals. Challenges such as multifunctional integration, interfacial adhesion, regulatory compliance, and the need for standardized evaluation metrics are discussed. Finally, future directions in predictive molecular design and high-throughput screening are outlined to accelerate the development of next-generation self-healing coatings (SHC) across diverse Asian industrial sectors.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e70290"},"PeriodicalIF":3.3,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144999351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Simultaneously, UOR facilitates wastewater remediation, offering dual environmental and energy benefits. In this work, we report a MnCO3/Ni(OH)2 heterostructured nanoflower array directly grown on conductive carbon cloth that exhibits outstanding UOR catalytic activity and stability. The catalyst achieves remarkably low overpotentials of 90 mV at 10 mA·cm-2 and 167 mV at 200 mA·cm-2, along with excellent long-term durability under continuous operation. Comprehensive characterization and mechanistic analysis reveal that the enhanced performance originates from interfacial electronic redistribution at the MnCO3/Ni(OH)2 junction. This electronic interaction promotes the stabilization of highly-valent Ni active species and improves electrode wettability, thereby facilitating efficient charge transfer and mass transport. This study underscores the critical role of heterointerface engineering and compositional modulation in developing robust and high-performance UOR electrocatalysts, providing valuable insights for their practical deployment in sustainable hydrogen generation and environmental remediation.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e00828"},"PeriodicalIF":3.3,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144999272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results revealed that excited-state intramolecular proton transfer is responsible for the dual emission properties of such molecules. The conclusions are made based on the computed vibrational frequencies, excited state antiaromaticity, potential energy surfaces, absorption and emission spectra, and finally, from the excited state dynamics. The calculations showed that the dual emission property is most effective for primary PAOHBA, followed by secondary PAOHBA, and tertiary PAOHBA.
