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

Abstract

Abstract In this study, a novel naphthalene schiff-base as a dual-analyte fluorescent sensor for Zn 2+ and Cu 2+ has been designed and synthesized. The sensor shows significant fluorescence enhancement in the presence of Zn 2+ , which might be attributed to inhibit ESIPT process, in contrast, its fluorescence is quenched by Cu 2+ owing to its inherent to the magnetic property. More interestingly, we have successfully utilized the two metal ions (Cu 2+ and Zn 2+ ) as chemical inputs for the manufacture of INHIBIT type logic gate.
