摘要：
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. (C) 2016 Elsevier B.V. All rights reserved.
