1,8-萘酰亚胺基金离子荧光探针的构建及其对环境水样中金离子的测定
Construction of 1,8-Naphthalimide-based Gold Ions Fluorescent Probe and Its Detection of Gold Ions in Environmental Water Samples
摘要
Abstract
The emission of gold ions(Au3+)poses severe threats to human health,the environment,and plant growth.Therefore,rapid and precise detection of Au3+is of great significance.In this work,a 1,8-naphthalimide-based Au3+fluorescent probe A1 was synthesized using(Z)-3-methyl-pent-2-en-4-yn-1-ol as the recognition group.In the presence of Au3+,the(Z)-3-methylpent-2-en-4-yn-1-ol of probe A1 was catalytically converted into a furan structure,leading to the quenching of its cyan fluorescence.The sensing mechanism was confirmed through high-resolution mass spectrometry(HR-MS)and theoretical calculations.Probe A1 exhibits advantages such as good selectivity,high sensitivity(5.27 µmol/L),and a wide pH range of applicability(3.0-10.5)for Au3+response.Rap-id quantitative detection of Au3+in real water samples can be achieved through smartphone-assisted probe A1-based solution colorimetric analysis.关键词
