A colorimetric and fluorescent chemosensor for detection of Hg2+ using counterion exchange of cationic polydiacetylene
Tetrahedron Letters（2017）
摘要
•A chemosensor for Hg2+ was developed using counterion exchange of cationic PDA.•It shows colorimetric and fluorescence response toward Hg2+ and allows naked-eye detection.•It is applied to determine Hg2+ concentrations in tap water samples.
