摘要

开发潜在的有毒金属离子探针在环境检测领域具有重要意义。本文结合方酸和亚胺基团的特点，构建了两种方酰胺配体（2a、2b）。2a 和 2b 可识别 Cu2+ 和 Cd2+，LOD 分别为 1.26 × 10-8 M 和 2.04 × 10-8 M，具有响应速度快、pH 值范围广等优点。通过约伯图、ESI-MS 和 1H NMR 测定了探针与目标离子的结合率和结合模式。

Two Squaramide-Based Fluorescent Probes for Cu²⁺ and Cd².

The development of potential toxic metal ion probes is of great significance in the field of environmental detection. Herein, two squaramide ligands (2a, 2b) were constructed by combining the characteristics of squaric acid and imine groups. 2a and 2b can recognize Cu²⁺ and Cd²⁺, with LOD of 1.26 × 10^-8 M and 2.04 × 10^-8 M, respectively, and have the advantages of fast response and wide pH range. The binding ratio and binding mode of the probe and the target ion were determined by Job's plot, ESI-MS, and ¹H NMR.

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.
