Abstract

Abstract: A naphthyl thiourea‐based effective chemosensor HNC, ( E )‐2‐(2‐hydroxy‐3‐methoxybenzylidene)‐ N ‐(naphthalen‐1‐yl)hydrazine‐1‐carbothioamide, was synthesized. HNC showed quick responses toward Ag + and Zn 2+ through marked fluorescence turn‐on in different solvent conditions, respectively. Binding proportions of HNC to Ag + and Zn 2+ were found to be 2:1 and 1:1, respectively. Detection limits of HNC for Ag + and Zn 2+ were calculated as 3.82 and 0.21 μM. Binding processes of HNC for Ag + and Zn 2+ were represented using Job's plot, DFT, 1 H NMR titration, and ESI‐MS.

Detection limits of KKW for Ag + and Zn 2+ were calculated as 3.82 and 0.21 μM, and binding processes of KKW for Ag + and Zn 2+ were illustrated with Job plot, DFT, NMR titration, and ESI‐MS.
