A novel coumarin-based fluorescent probe LY was designed and synthesized in this work. LY could selectively recognize Cu via fluorescence quenching at 522 nm in a DMSO/HO solution. The recognition process experienced minimal interference from other common cations. The binding ratio of LY to Cu was found to be 1:1, while the detection limit was calculated to be 4.6 × 10 M with the binding constant of 2.42 × 10 M. Additionally, LY was effectively utilized for detecting Cu in real water samples and with test papers, demonstrating its applicability.
在本研究中设计并合成了一种新型的基于香豆素的荧光探针LY。在二甲基亚砜/水体系中，LY可通过522nm处的荧光猝灭选择性识别铜离子。该识别过程受其他常见阳离子的干扰极小。发现LY与铜离子的结合比为1:1，检测限计算为4.6×10⁻⁸M，结合常数为2.42×10⁵M。此外，LY有效地用于实际水样和试纸中铜离子的检测，证明了其适用性。
