Different types of nitrene precursors have been exploited and successfully applied in a variety of nitrene-based transformations for the direct construction of nitrogen-containing compounds with structural complexity. Although a few of review articles that focus on the specific nitrene precursors or different type of nitrene reactions have been reported, significant advancements have emerged over the past two decades driven by the introduction and application of novel nitrene precursors, enabling a variety of catalytic transformations for the synthesis of N-heterocyclic frameworks with structural diversity. Thus, a review paper that underscores the progress in nitrene chemistry by focusing on the advancements in nitrene precursors would be timely and highly desirable. In this review article, the advancements in nitrene chemistry, particularly those achieved with newly developed nitrene precursors over the past two decades, have been summarized. The presentation is organized by the type of precursor and further subdivided based on different nitrene reactions by focusing on the key mechanistic aspects, limitation, and synthetic capacity.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202401521"},"PeriodicalIF":3.5,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143363376","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}

Electrochemical energy systems like batteries and supercapacitors have seen notable development to meet this demand. However, conventional polymeric membrane separators in these systems face challenges due to limited porosity and poor mechanical and thermal properties, reducing overall electrochemical performance. Researchers have incorporated nanoparticles into the polymer matrix to address these limitations and enhance separator properties. Carbon-based nanomaterials, in particular, have gained prominence due to their unique features, such as surface-dependent characteristics, size, porosity, morphology, and electrical conductivity. These properties make carbon-based nanomaterials advantageous in improving energy storage compared to conventional materials. Advanced carbon-doped polymeric membrane separators have emerged as a potential solution to the issues faced by conventional separators. Adding carbon nanoparticles, such as graphene-based materials and carbon nanotubes to the polymeric separators of batteries and supercapacitors has helped researchers solve problems and improve the electrochemical performance. This review article provides a state-of-the-art overview of carbon-doped polymeric membrane separators, their properties, fabrication processes, and performance in lithium batteries, as well as supercapacitors. It emphasizes advantages of these novel separator materials and suggests future research directions in this field.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202401618"},"PeriodicalIF":3.5,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143254115","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 imidazole protons, influenced by the Ru2+ centers, facilitate interactions with anions like F- and CN- in acetonitrile, and CN- in water, through hydrogen bonding or via proton abstraction. The spectral properties of the metalloreceptors change in the presence of these anions, and the initial state can be restored with acid, allowing recycling. The complexes exhibit Boolean logic functions (Implication logic gates) using spectral outputs in the presence of specific anions and acids. To address the time and cost constraints of executing comprehensive sensing experiments, an adaptive neuro-fuzzy inference system (ANFIS) with five membership functions (triangular, trapezoidal, generalized bell-shaped, Gaussian, and pi-shaped) was used to predict experimental data and appropriate modeling of the sensing characteristics. Comparison of ANFIS model outputs with experimental data showed a good correlation, with the Gaussian and generalized bell-shaped functions providing high accuracy and close resemblance to experimental data. This neuro-fuzzification approach promises accurate prediction and modeling of sensing data for Ru(II)-based metalloreceptors.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202401346"},"PeriodicalIF":3.5,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143363374","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 investigation, a naphthalimide-rhodamine based dual-chromophore, RNI-P, was synthesized and applied to detect nerve-agent mimic diethyl chlorophosphate (DCP) and real nerve agents. The probe exhibits inherently weak fluorescence due to the PET processes from both piperazine and rhodamine units to the naphthalimide unit. It shows rapid fluorescence enhancement to DCP in aqueous solution, demonstrating exceptional sensitivity and selectivity. Furthermore, the probe-inked paper strip can also rapidly respond to DCP vapor when integrated into a lab-made portable sensing platform. The detection limit to DCP vapor can be as low as 130 ppb. Most notably, the probe is capable of quickly and effectively detecting real nerve agents such as sarin and soman in aqueous solution, highlighting its significant potential for practical use. The turn-on responses are attributed to the prohibition of PET processes through protonation of the probe. This study reveals that not only the usual nucleophilic groups but also a second fluorophore can cause effective PET process to the core chromophore and empowers the probe with strong potential for efficient detection of nerve agents.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202401491"},"PeriodicalIF":3.5,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143363372","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}

Its cheapness, ease of synthesis, high water-solubility, tunable emission, and excellent biocompatibility make it a single-point solution to many problems, and tremendous efforts were invested into understanding the structure-property-function relationship, which eases the engineering of the CD properties suitable for a desired application. From the usual random choice of precursors or carbon materials as a starting point in the early days, more systematic approaches are now available for choosing proper starting materials and appropriate experimental conditions (solvent medium, reaction temperature, reaction duration, pH, etc) to customize its photoluminescence. The presence of impurities has a crucial role in the outcome and applicability of photoluminescence. Recently, a significant focus has been on the long-wavelength emissive CDs, particularly in the red to near-infrared (NIR) regions, for better penetration into live cells and to circumvent autofluorescence problems. Proper design can harvest phosphorescence from CDs. Many excellent reviews are available, focusing on different facets of CD prospects. Hence, we will only highlight the importance of the optical properties of CDs. We will mention some of the new works that have appeared in the last five years.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202401470"},"PeriodicalIF":3.5,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143187622","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}
