Title
Fluorescent chemosensor for detection of Zn2+ and Cu2+ and its application in molecular logic gate
Abstract

•A multifunctional fluorescent probe for Zn2+/Cu2+ has been designed and synthesized.•The sensor shows significant fluorescence enhancement in the presence of Zn2+, due to inhibit ESIPT process.•We have successfully utilized the two metal ions (Cu2+ and Zn2+) as chemical inputs for the manufacture of INHIBIT type logic gate.

In this study, a novel naphthalene schiff-base as a dual-analyte fluorescent sensor for Zn2+ and Cu2+ has been designed and synthesized. The sensor shows significant fluorescence enhancement in the presence of Zn2+, which might be attributed to inhibit ESIPT process, in contrast, its fluorescence is quenched by Cu2+ owing to its inherent to the magnetic property. More interestingly, we have successfully utilized the two metal ions (Cu2+ and Zn2+) as chemical inputs for the manufacture of INHIBIT type logic gate.
