A new simple and efficient fluorescent sensor L based on 1,8‑diaminonaphthalene Schiff-base for highly sensitive and selective determination of Cu in drink and water has been developed. This Cu-selective detection over other tested metal ions displayed an obvious color change from blue to colorless easily detected by naked eye. The detection limit is determined to be as low as 13.2 nM and the response time is very fast within 30 s. The 1:1 binding mechanism was well confirmed by fluorescence measurements, IR analysis and DFT calculations. Importantly, this sensor L was employed for quick detection of Cu in drink and environmental water samples with satisfactory results, providing a simple, rapid, reliable and feasible Cu-sensing method.
一种基于 1,8-二氨基萘席夫碱的新型简单高效荧光传感器 L 已被开发出来，用于高度灵敏和选择性地测定饮料和水中的 Cu。与其他测试的金属离子相比，这种 Cu 选择性检测显示出明显的颜色变化，从蓝色变为无色，肉眼很容易检测到。检测限低至 13.2 nM，响应时间非常快，在 30 s 内。荧光测量、IR 分析和 DFT 计算很好地证实了 1:1 的结合机制。重要的是，该传感器 L 被用于快速检测饮料和环境水样中的 Cu，结果令人满意，为 Cu 传感提供了一种简单、快速、可靠和可行的方法。
