摘要：
A rhodamine-based fluorescence chemsensor bearing the 8-hydroxyquinoline unit is developed as a reversible turn-on chemosensor for Cu2+. It exhibits a highly sensitive fluorescent response toward Cu2+ in aqueous media with an 80-fold fluorescence intensity enhancement under 10 equiv. of Cu2+ added. This indicates that the synthesized chemosensor effectively avoided the fluorescence quenching for the paramagnetic nature of Cu2+ via its strong binding capability toward Cu2+. The chemosensor Rh-Q exhibits a dynamic response range for Cu2+ from 2 ×10-7 to 5 ×10-5 M, with a detection li...
