A Colorimetric and Fluorescent Chemosensor for Cu2+ Detection in Aqueous Solution

A novel fluorescent chemosensor, 10-(benzo[d]thiazol-2-yl)-2,3,6,7-tetrahydro- 1H-pyrano[2,3-f]pyrido[3,2,1-ij]quinolin-11(5H)-imine(L), was been successfully developed and well characterized. Sensor L exhibits high selectivity for Cu 2+ over other ions (Ag + , Pb 2+ , Cu 2+ , Ni 2+ , Fe 3+ , Co 2+...

Summary:A novel fluorescent chemosensor, 10-(benzo[d]thiazol-2-yl)-2,3,6,7-tetrahydro- 1H-pyrano[2,3-f]pyrido[3,2,1-ij]quinolin-11(5H)-imine(L), was been successfully developed and well characterized. Sensor L exhibits high selectivity for Cu 2+ over other ions (Ag + , Pb 2+ , Cu 2+ , Ni 2+ , Fe 3+ , Co 2+ , Zn 2+ , Hg 2+ , and Cd 2+ ) with colorimetric and fluorescence turn-off properties in aqueous solutions. Furthermore, the reversible recognition process was confirmed by EDTA experiment and sensor L showed practical application in detection Cu 2+ in tap water.
