摘要

甲醇已成为许多行业非常重要的组成部分,从化工生产和制药到汽车和电子制造,甲醇的使用量近年来激增。但这种指数式的增长需要精确的检测方法,因为甲醇不仅会对环境产生有害影响,而且即使摄入微量甲醇也会对人体健康造成严重危害。本文将探讨甲醇的独特物理和化学特性,这些特性可被各种小分子和纳米颗粒利用,使其成为不同机制的目标,如 H 键、诱导自组装、内部电荷转移 (ICT)、聚集诱导发射 (AIE)、构象灵活性、酮烯醇共聚、吸附等。关于小分子的信息研究涉及官能化的五并蒽醌衍生物、发光剂、配体和荧光探针,它们可以通过颜色或强度的变化来检测甲醇,这种检测可以很容易地进行实时检测,而且便于携带。另一方面,基于纳米粒子的探针揭示了壳聚糖/锌、硫化物复合材料、量子点(QDs)混合体、石墨烯聚氧乙烯醚、Ag-LaFeO3 等材料的使用,这些材料可提供选择性和灵敏的甲醇光学和电导检测。本文感谢为推动甲醇传感领域的发展做出贡献的各种研究和研究人员,他们为未来的发展奠定了基础。

Precision Methanol Sensing: Integrating Chemical Insights of Optical Sensors for Enhanced Detection.

Methanol has become a very important part of many industries, ranging from chemical production and pharmaceuticals to automotive and electronics manufacturing as a result of which methanol usage has spiked in recent years. But this exponential increase asks for precise detection methods as methanol has not only detrimental effects on environment but it is very dangerous to human health even if consumed in a minute amount .This paper will explore the unique physical and chemical properties of methanol which can be exploited to make it a target for different mechanisms such as H-Bonding, induced self-assembly, Internal Charge Transfer (ICT), Aggregation-induced emission (AIE), conformational flexibility, keto-enol tautomerization, adsorption etc. by various small molecule and nano-particles. Informative studies on small molecules involves functionalized pentacenequinone derivatives, luminogens, ligands and fluorescent probes which can be used to detect methanol by change in color or intensity which can be easily detected in real time and is portable. On the other hand, nanoparticle-based probes reveal the use of materials like chitosan/zinc, sulfide composites, Quantum Dots (QDs) hybrids, graphene polyoxides, Ag-LaFeO3 etc. which provides with selective and sensitive methanol optical and conductometric sensing. This paper acknowledges the contributions of various studies and researchers who contributed to advancing the field of methanol sensing, providing a foundation for future developments.

期刊介绍: Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
