摘要：

An "off-on'' Zn2+ and "on-off'' Cu2+ fluorescent chemosensor C was designed and synthesized. The binding of C and Zn2+/Cu2+ is chemically reversible by the addition of EDTA disodium solution; moreover, the fluorescence emission signal of ZnC decreased with the addition of Cu2+, demonstrating that ZnC could detect Cu2+ via metal displacement.
