摘要

通过 Cu2+ 对希夫碱探针的荧光淬灭,荧光探针提供了一种简单的 Cu2+ 检测方法。然而,偶氮基探针通常在水中的溶解性和分散性较差,而且容易受到其他竞争离子的干扰,这大大降低了其应用潜力。在本研究中,我们合成了一种水溶性高荧光γ-环糊精(γ-CD)/2-羟基苯甲醛偶氮(2-HBA)包合复合物,用于 Cu2+ 检测。在 γ-CD 中加入 2-HBA 可提高其在水中的溶解度,并使其发出荧光。合成的 γ-CD/2-HBA 探针对 Cu2+ 的比色和荧光检测具有很高的灵敏度,检测限分别达到 2.72 和 1.53 nM。其结果超过了大多数文献报道。实验和理论方法对该探针的结构和潜在机制进行了系统分析。

2‐Hydroxybenzaldehyde Azine and γ‐Cyclodextrin Based Colorimetric/Fluorescent Probe for Highly Sensitive and Selective Detection of Cu2+
The fluorescent probe provides a simple for detecting Cu2+ through fluorescence quenching of the Schiff‐base probes by Cu2+. However, the azine‐based probes often suffer from poor solubility and dispersibility in water and are easily interfered with by other competing ions, which significantly reduces their applicable potential. In this study, we synthesized a water‐dissoluble and highly fluorescent γ‐Cyclodextrin (γ‐CD)/2‐hydroxybenzaldehyde azine (2‐HBA) inclusion complex for Cu2+ detection. The inclusion of 2‐HBA into γ‐CD enhances its solubility in water and allows it to emit fluorescence. The as‐synthesized γ‐CD/2‐HBA probe exhibits high sensitivity for colorimetric and fluorescent detection of Cu2+, with detection limits reaching 2.72 and 1.53 nM, respectively. The results exceed most of those reported in the literature. The probe’s structure and potential mechanism were systematically analysed using the experimental and theoretical methods.
