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.
