A (3 ¡Á 10-5mol / L, water) and metal ions Na +, K +, Mg2 +, Ca2 +, Ba2 +, Fe3 +, Cu2 +, Cd2 + and Pb2 + interaction (metal ions to 9 ¡Á 10-5mol / L), the A's fluorescencehave different degrees of quenching, but when the Zn2 + in the case of the same is introduced into the, a quenched the fluorescence emission peak at 370 nm at the same time, in the 454 nm fluorescence peak at significantly enhanced, showing the ratio of fluorescence characteristics, therefore,compound A has the basic conditions as the ratio of fluorescence detection Zn2 + probe.

When A (3 ¡Á 10-5mol / L, water) interacted with Na+, K+, Mg2+, Ca2+, Ba2+, Fe3+, Cu2+, Cd2+ and Pb2+ (metal ions 9 ¡Á 10-5mol/L), variable fluorescence quenching of A was seen. However, when Zn2+ was introduced in this case, A showed significantly increased intensity of fluorescence emission peak at 454 nm on quenching of the fluorescence emission peak at 370 nm, exhibiting ratiometric fluorescence. Therefore, compound A meets the prerequisite for ratiometric fluorescent probe for detecting Zn2+.
