摘要

硫化物（S2−）和锌（Zn2+）离子的高效检测在工业、生物和环境领域具有重要意义。本文以双醛和二胺为前体，采用模板辅助环缩合反应合成了一种新型的希夫碱大环单核铽配合物Tb-2l，并通过系列表征技术系统地研究了配合物Tb-2l的精确结构。在仔细评估了15个阴离子和19个阳离子在三个发射波段（451,543和632 nm）上的传感信号后，证明了配合物Tb-2l是一种实时、选择性和敏感的S2−和Zn2+荧光增强探针。利用统计分析方法，配合物Tb-2l进一步显示出对13种阴离子和16种阳离子的高通量识别能力，特别是对阴离子和阳离子类似物的几组高通量识别能力。通过应用程序提取RGB值，开发了基于智能手机的分析方法，即使在真实环境水样中，也可以方便地现场检测复杂的Tb-2l对S2−和Zn2+的检测。这项工作不仅有助于加深对镧系材料和发光的理解，而且为检测常见无机离子提供了可靠的分析工具，展示了其在各个领域的应用潜力。

A terbium-macrocycle as fluorescence-enhanced probe for selective and quantitative detection of sulfur and zinc ions

The highly-efficient detection of sulfide (S²⁻) and zinc (Zn²⁺) ions is of significant importance due to their essential roles in industrial, biological and environmental areas. In this paper, a novel Schiff-base macrocyclic mononuclear terbium complex Tb-2_l is synthesized from dialdehyde and diamine precursors upon the template-assisted cyclocondensation reaction, and its precise structure of complex Tb-2_l is systematically studied by serial characterization techniques. After the careful evaluation of these sensing signals for 15 anions and 19 cations on three emission bands (451, 543 and 632 nm), the complex Tb-2_l is proven to be a real-time, selective and sensitive fluorescence-enhanced probe for S²⁻ and Zn²⁺. Using statistical analysis methods, complex Tb-2_l further shows its high-throughput discrimination ability of 13 anions and 16 cations, especially several groups of anionic and cationic analogues. By RGB values extracted by an APP, the smartphone-based analysis method is also developed to provide the convenient and on-site detection of S²⁻ and Zn²⁺ by complex Tb-2_l, even in real environmental water samples. This work not only contributes to a deeper understanding of lanthanide-based material and luminescence but also offers a reliable analytical tool for detecting common inorganic ions, demonstrating its potential for application in various fields.

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
